7. Using ALTI & BARO mode

In the ALTI & BARO mode you can view the current altitude, barometric pressure or snorkeling depth. It offers four profiles: AUTOMATIC, ALTIMETER, BAROMETER and DEPTH METER (see 7.2.2. Setting profiles). You can access different views depending on which profile is activated when you are in the ALTI & BARO mode.

[Visual: Diagrams showing ALTI & BARO mode displays for altitude, pressure, and depth.]

7.1. How Alti & Baro works

To get the right readings from ALTI & BARO, it is important to understand how Suunto Core calculates altitude and sea level air pressure. Suunto Core constantly measures absolute air pressure. Based on this measurement and reference values, it calculates altitude or sea level air pressure.

⚠️ CAUTION: Keep area around sensor free of dirt and sand. Never insert any objects into the sensor openings.

7.1.1. Getting correct readings

If you are engaged in an outdoor activity that requires you to know the air pressure, you need to enter the altitude reference value for your location. This is found on most topographic maps. Your Suunto Core will now give you the correct readings.

To get the correct altitude readings, you need to enter the sea level air pressure reference value. The sea level air pressure reference value relevant to your location can be found in the weather section of the local newspaper or on the websites of national weather services.

Absolute air pressure is measured constantly Absolute air pressure + altitude reference = Sea level air pressure

* Absolute air pressure + sea level air pressure reference = Altitude *

Changes in local weather conditions will affect altitude readings. If local weather changes often, it is advisable to reset the current altitude reference value frequently, preferably before starting your journey when the reference values are available. If local weather is stable, you do not need to set reference values.

7.1.2. Getting incorrect readings

altimeterAltimeter profile + standing still + weather change

If your ALTIMETER profile is on for an extended period of time with the device in a fixed location while the local weather changes, the device will give incorrect altitude readings.

altimeterAltimeter profile + altitude moving + weather change

If your ALTIMETER profile is on and the weather changes frequently while you climb in altitude or go down in altitude, the device will give you incorrect readings.

BarometerBarometer profile + altitude moving

If the BAROMETER profile is on for an extended period of time as you climb in altitude or go down in altitude, the device assumes that you are standing still and interprets your changes in altitude as changes in sea level air pressure. It will therefore give you incorrect sea level air pressure readings.

You're on the second day of your two-day hike. You realize that you forgot to switch from the BarometerBarometer profile to the altimeterAltimeter profile when you started moving in the morning. You know that the current altitude readings given by your are wrong. So, you hike to the nearest location shown on your topographic map for which a altitude reference value is provided. You correct your altitude reference value accordingly. Your altitude readings are correct again.

7.2. Setting profiles and reference values

7.2.1. Matching profile to activity

The ALTIMETER profile should be selected when your outdoor activity involves changes in altitude (e.g. hiking in hilly terrain). The BAROMETER profile should be selected when your outdoor activity does not involve changes in altitude (e.g. surfing, sailing). To get the correct readings, you need to match the profile to the activity. You can either let Suunto Core decide which profile is most suitable for you at the moment, or you can choose a suitable profile yourself.

7.2.2. Setting profiles

To set the profile:

1. In MENU, select ALTI-BARO.
2. Select PROFILE.
3. Choose a suitable profile.

Alternatively you can set the profile in the ALTI & BARO mode by keeping [View] pressed down.

7.2.3. Setting reference values

To set the reference value:

1. In MENU, select ALTI-BARO.
2. Select REFERENCE and choose between the ALTIMETER and SEA LEVEL.
3. Set the known reference value using [+] and [- Light] .

[Visual: Diagram showing altitude reference (80 ft) and sea level reference (1020 hPa).]

You're hiking and take a break when you see a sign with the current altitude. You check your altitude reading and discover a small difference between the two numbers. You set the altitude reference value on your to match that of the sign.

7.3. Using weather trend indicator

The weather trend indicator is located on the upper side of the display. It is displayed in the TIME and ALTI & BARO modes, providing you with quick reference to check upcoming weather conditions. The weather trend indicator is comprised of two lines forming an arrow. Each line represents a 3-hour period. The right line represents the last 3 hours. The left line represents the 3 hours prior to the last 3 hours. So the line can indicate 9 different patterns in the barometric trend.

TIP: If the weather trend indicator shows that the air pressure is constantly rising, there is a higher possibility of sunny weather upcoming. Again, if the air pressure is constantly dropping, there is a higher possibility of rainy weather.

7.4. Activating storm alarm

The storm alarm notifies you that a pressure drop of 4 hPa / 0.12 inHg or more has occurred during a 3-hour period. Suunto Core will activate an alarm and flash an alarm symbol on the display for 20 seconds. The storm alarm only works when you have activated the BAROMETER profile in the ALTI & BARO mode.

To activate the storm alarm:

1. In MENU, select ALTI-BARO.
2. Select STORM ALARM.
3. Switch the storm alarm on or off with [+] and [- Light] .

TIP: You can stop the storm alarm by pressing any button.

You are hiking in a dense forest when your activates the storm alarm. The weather has taken a turn for the worse in the last 3 hours - the sky is getting dark. Good thing your warned you, because you need to find shelter from the hard rain that may soon fall.

7.5. Using altimeter profile

The ALTIMETER profile calculates altitude based on the reference values. The reference values can either be sea level air pressure or a previous point of altitude reference value. When the ALTIMETER profile is activated, the word ALTI is underlined on the display.

When the ALTIMETER profile is activated, you can access the following views with [View] :

• Log recorder: records the altitude changes into logs
• Altitude difference measurer: measures the altitude difference from a set point
• Temperature: measures the current temperature
• Empty: no supplementary information

[Visual: Diagram of the ALTI mode display showing altitude and temperature.]

7.5.1. Using altitude difference measurer

The altitude difference measurer shows the difference in altitude between a set point and your current position. This feature is especially useful for mountain climbing, for example when you want to track your progress in terms of altitude climbed.

To use the altitude difference measurer:

1. In the ALTI & BARO mode, select the altitude difference measurer view.
2. Start, stop and restart it with [Start Stop] .
3. Keep [+] pressed to reset.

You are about to start climbing a mountain that is 3, 280 feet (1000 m) high. You want to be able to check your progress as you climb, so you activate the altitude difference measurer on your . You start climbing, checking your altitude occasionally to see how far you are from the next check point. At some point you start to get tired. You check your altitude, and see that there's still a lot of climbing ahead. Maybe you need to rethink your next check point.

7.5.2. Recording logs

The log recorder stores all your movements in altitude between the start and stop times. If you are engaged in an activity in which your altitude changes, you can record the altitude changes and view the stored information later.

You can also set altitude marks (laps), allowing you to view the duration and ascent/descent height between your previous mark and current mark. Your marks are stored in memory and you can access them later.

To record a log:

1. In the ALTI & BARO mode, select the log recorder view.
2. Start, stop and restart it with [Start Stop] .
3. When you are recording a log, set laps with [+] .
4. Keep [+] pressed to reset (this can only be done when the recorder is stopped).

Log height difference: shows the measured altitude difference between a log starting point and a log finishing point with the following icons:

Altitude points are recorded according to the recording interval you have chosen (see 9.3. Choosing recording interval).

To change the recording rate:

1. In MENU, select MEMORY.
2. Select REC INTERVAL.
3. Change the recording rate with [+] and [- Light] .

? NOTE: An estimation of how much time you can record is shown in the lower part of the display when you browse between the recording rates. The actual recording durations may vary slightly depending on your activity during the recording period.

You can access your history of recorded logs, including log details, from LOGBOOK in MENU (see 9.2. Viewing and locking logs).

TIP: When you have stopped the log recorder, you can enter the logbook and view your current recordings before you reset the recorder.

You're going on another mountain hike. This time you want to record how much you ascend and descend so as to compare the figures with previous hikes. You set your to the altimeterAltimeter profile and start the log recorder when you begin the hike. After the hike you stop your log recorder and reset it . Now you can compare it with your previous logs.

7.6. Using barometer profile

The BAROMETER profile shows the current sea level air pressure. This is based on the reference values given and the constantly measured absolute air pressure. Changes in sea level air pressure are presented graphically in the middle of the display. The display shows the recording of the last 24 hours with a recording interval of 30 minutes.

When the BAROMETER profile is activated, the word BARO is underlined on the display. When the BAROMETER profile is activated, you can access the following views with [View] :

• Temperature: measures the current temperature
• Log recorder: records the altitude changes in logs
• Altitude reference: shows the altitude reference value
• Time: shows the current time
• Empty: no additional view

[Visual: Diagram of the BARO mode display showing pressure and temperature.]

? NOTE: If you are wearing your Suunto Core on your wrist, you will need to take it off in order to get an accurate temperature reading because your body temperature will affect the initial reading.

A 7-day log of changes in sea level air pressure can be viewed in ALTI-BARO memory in MENU (see 9.1. Alti-baro memory).

You're still hiking and you're getting tired. You decide to take a nap and you set up your tent. Since your altitude will stay the same for a while, you activate the BarometerBarometer profile. When you wake up, you will be able to check changes in sea level air pressure with an eye on the weather.

7.6.1. Recording logs

When you are recording logs in the ALTIMETER profile, you can switch to the BAROMETER profile when you for example take a break during a hike. The log recorder will continue recording the log, but it will not record changes in air pressure. When the barometer profile is activated, the device assumes you are not moving in altitude, and it will therefore not record any altitude changes. The altitude log will therefore be flat during this period. For information on using the log recorder, see 7.5.2. Recording logs. You can start, stop and reset the altitude measurement while in the BAROMETER profile.

You are recording your altitude changes during a hike and decide to take a longer break. You switch to the BarometerBarometer profile. Since the altitude recording continues but no altitude changes are occurring, you go to the log recorder view in the BarometerBarometer profile and stop the altitude recording.

7.7. Using automatic profile

The AUTOMATIC profile switches between the ALTIMETER and BAROMETER profiles according to your movements. When the AUTOMATIC profile is activated, [auto icon] appears on the upper right part of the display. Depending on which profile is activated, you can access the ALTIMETER or BAROMETER profile views with [View] .

When the device is moving 5 meters in altitude within 3 minutes, the ALTIMETER profile is activated. When the device does not move in altitude for 12 minutes, the BAROMETER profile is activated.

? NOTE: The AUTOMATIC profile should not be activated all the time. Some activities require the BAROMETER profile to be constantly activated even though you might be moving (e.g. surfing). In other words, in certain situations you need to choose a suitable profile manually.

7.8. Using depth meter profile

You use the DEPTH METER profile when snorkeling. It shows your current depth and the maximum depth you reached during a snorkeling dive. The maximum depth of the device is 32.8 ft (10m). When the DEPTH METER profile is activated, a wave icon ? appears on the upper left part of the display.

When the DEPTH METER profile is activated, you can access the following views with [View] :

• Log recorder: records your snorkeling dives
• Temperature: measures the current temperature
• Time: shows the current time

[Visual: Diagram of the DEPTH METER profile display showing depth and time.]

7.8.1. Recording logs in depth meter profile

The log recorder in the DEPTH METER profile works similarly to the log recorder in the ALTIMETER profile, but instead of recording altitude it records the depth of your snorkeling dives.

To record logs in the DEPTH METER profile:

1. In the ALTI & BARO mode, select the log recorder view.
2. Start, stop and restart it with [Start Stop] . Begin a snorkeling dive.
3. When you return to the surface, reset by holding [+] pressed.

⚠️ CAUTION: Do not push buttons while the device is under water.

? NOTE: You need to reset your log recorder in the ALTIMETER profile before using the log recorder in the DEPTH METER profile. Otherwise, your maximum depth will stay the same as your current altitude above the surface.

TIP: When you have stopped your log recorder, before resetting it, you can enter the logbook and view your current recordings!

8. Using compass mode

The COMPASS mode allows you to orient yourself in relation to magnetic North. In COMPASS mode you can access the following views with [View] :

• Time: shows the current time
• Cardinals: shows the current heading in cardinal directions
• Bearing tracking:shows the direction between the heading and set bearing.

The compass will switch itself to power saving mode after a minute. Reactivate it with [Start Stop] .

8.1. Getting correct readings

To ensure correct compass readings while in COMPASS mode: COMPASS

• calibrate the compass correctly when prompted (see 8.1.1. Calibrating compass)
• set the correct declination value
• keep the device level
• keep away from metal (e.g. jewelry) and magnetic fields (e.g. power lines)

8.1.1. Calibrating compass

The device needs to be carefully calibrated during first time use and when the battery is replaced. The device will always prompt you about it when it is needed.

To calibrate the compass:

1. Keep the device level, do not tilt it in any directions.
2. Slowly rotate the device clockwise (around 15 seconds per round) until the compass is activated.

? NOTE: If you notice deviations in the compass, you can recalibrate it by keeping it level and rotating it slowly clockwise 5-10 times while in compass mode.

TIP: Re-calibrate the compass before each use for best possible accuracy.

8.1.2. Setting declination value

Paper maps point to true North. Compasses, however, point to magnetic North – a region above the Earth where the Earth's magnetic fields pull. Because magnetic North and true North are not at the same location, you must set the declination on your compass. The angle in between magnetic and true north is your declination.

[Visual: Diagram showing declination angle.]

The declination value appears on most maps. The location of magnetic North changes yearly, so the most accurate and up-to-date declination value can be obtained from the internet (for example the National Geophysical Data Center for the USA).

Orienteering maps, however, are drawn in relation to magnetic North. This means that when you are using orienteering maps you need to turn the declination correction off by setting the declination value to 0 degrees.

To set the declination value:

1. In MENU, select COMPASS.
2. Turn the declination off or choose W (west) or E (east).
3. Set the declination value with [+] and [- Light] .

8.2. Using compass

When you are in the COMPASS mode, you see two moving segments on the rim of the display. These point towards North. The hairline at 12 o'clock shows your heading and functions as a compass direction arrow. The numerical value of your heading is shown in the center of the display.

In COMPASS mode you can access the following views with [View]:

• Time: shows the current time
• Cardinals: shows the current heading in cardinal directions
• Bearing tracking: shows the direction between the heading and the set bearing

The compass will switch itself to power saving mode after a minute if no buttons are pressed. Reactivate it with [Start Stop] .

You can use the compass in two ways: you can use the bezel or the bearing tracking.

[Visual: Diagram of compass display with bearing.]

8.2.1. Using bearing tracking

In bearing tracking you can lock a bearing (direction) and your Suunto Core compass will guide you along it.

To use the bearing tracking:

1. Point the compass direction arrow in the direction you want to travel and press [Start Stop] . The bearing is now locked. Your current heading is shown in the middle of the display, and it will change according to your movements.
2. The arrows in the top row of the display point you in the direction you need to take in order to keep to your desired bearing. The symbol confirms that you are aiming towards the right direction.

? NOTE: Pressing [- Light] also activates the backlight.

You're hiking and you've just climbed a steep hill. Looking out over the valley below, you see a cabin on another hill. You decide to hike to the cabin through the valley. You point the direction arrow of your compass towards the cabin and lock the bearing. Once you're in the valley, the arrows in the display's top row show you where to go. Because the compass is active for only 40 seconds at a time to conserve battery life, now and then you need to re-start the compass to check your heading. Keep an eye on it and you'll get there soon.

9. Using memory

9.1. Alti-baro memory

ALTI-BARO automatically records changes in altitude or sea level air pressure for the last 7 days. Information will be stored depending on which profile is active at the moment of the recording. Records are stored every 30 minutes.

To view the records of the last 7 days:

1. In MEMORY, select ALTI-BARO.
2. Use [+] and [- Light] to browse through the records.

You are camping in the mountains. You want to predict tomorrow's weather, so you switch your to the BarometerBarometer profile for the night. In the morning you check the alti-baroalti-baro memory and note that the air pressure remained stable for the whole night. Hopefully this will continue during the day.

9.2. Viewing and locking logs

Logs recorded by the log recorder in the ALTIMETER, BAROMETER or DEPTH METER profile are stored in LOGBOOK. You can store up to 10 logs. A new log always replaces the oldest log in LOGBOOK. To save logs, you can lock them. A ? is shown when a log is locked. You can only lock up to 9 logs.

When entering LOGBOOK, you are shown the number of unlocked logs. You can then choose to either view or lock logs.

When you view logs, you are first shown a list of available logs complete with times and dates. You can scroll and then enter each log to view its summary information and details.

9.2.1. Viewing logs

• A summary graph, time of recording and highest point
• Total descent, duration of descent, average descent speed
• Total ascent, duration of ascent and average ascent speed
• Altimeter split time (total log duration from start) and lap times (duration since last lap time)

When viewing log details, you are shown:

• A graph of the changes in altitude
• Time of recording
• Altitude/depth at the time of recording

To view the logs:

1. In MEMORY, select LOGBOOK.
2. Choose a log from the list.
3. Select VIEW.
4. Switch between log summaries with [+] and [- Light] .
5. View log details with [Mode] .

6. Increase and decrease scrolling speed and change direction with [+] and [- Light] . Stop with [Mode] .

9.3. Choosing recording interval

You can choose the recording interval in REC INTERVAL in MENU.

You can choose between five recording intervals:

• 1 second
• 5 seconds
• 10 seconds
• 30 seconds
• 60 seconds

When browsing through the intervals, the available recording time is shown in the lower part of the display.

To choose a recording interval:

1. In MEMORY, select REC INTERVAL.
2. Choose a recording interval using [+] and [- Light] .

10. Care and support

10.1. Handling guidelines

Handle your Suunto Core with care. The sensitive internal electronic components may be damaged if the device is dropped or otherwise mishandled.

Do not try to open or repair your Suunto Core by yourself. If you are experiencing problems with the device, please contact your nearest authorized Suunto Service Center.

TIP: Remember to register your product at www.suunto.com/support to get personalized support.

Leather straps

Suunto Core leather straps are made from high quality natural hides. The performance and lifespan of these straps can differ from one strap to the next given the natural variation in the materials.

Usage also has a significant impact on the performance and lifespan of leather straps, much like belts, wallets and other items made from leather. Contact with fresh water, salt water, and perspiration may change the color and odor of the strap, as well as shorten its lifespan.

If you intend to swim, snorkel or participate in strenuous activities with yourSuunto Core, we recommend using a synthetic strap.

Cleaning

Regularly clean and dry your Suunto Core with fresh water and a soft cloth, particularly after heavy perspiration or swimming. Avoid getting leather straps wet.

10.2. Replacing battery

? NOTE: To reduce the risk of fire or burns, do not crush, puncture or dispose of used batteries in fire or water. Recycle or dispose of used batteries properly.

? NOTE: If the threads of the battery compartment cover are damaged, send your device to an authorized Suunto representative for service.

? NOTE: Suunto original battery replacement and strap kits must be used if available for your product. Kits are available at Suunto webshop and some authorized Suunto dealers. Not using these kits and careless battery replacement may void warranty.
