You can record a bearing to a destination. Enter Compass Mode, point towards the objective, and press E. This records the bearing, which can be useful in poor visibility.

Calibrating Compass Readings:

Perform 2-point calibration if readings are inaccurate or before critical activities. This involves rotating the watch 180 degrees at specific points as guided by the display. Magnetic declination (for True North readings) can also be calibrated using geographic maps for reference.

Digital Compass Reading Precautions: Avoid strong magnetism sources (magnets, metal objects, electrical appliances) as they can cause errors. Readings may also be inaccurate indoors or in moving vehicles.

Altitude Measurement

The watch measures altitude based on barometric pressure. Readings are relative and can be affected by weather changes and temperature. Regular calibration with local altitude data is recommended.

Checking the Current Altitude:

Enter the Altimeter Mode. The watch displays the current altitude. You can choose between an Altitude Graph Screen or an Altitude Differential Screen. The watch takes readings every second for the first three minutes, then at set intervals.

Calibrating Altitude Readings (Offset):

To improve accuracy, update the reference altitude value (offset) using known local altitude data. This helps minimize differences between the watch's readings and actual elevation.

Setting a Reference Altitude and Taking Altitude Differential Readings:

You can set your current location as a reference altitude (differential becomes ±0 m). This is useful for tracking altitude changes between two points while climbing or trekking.

Setting the Measurement Interval:

You can select an auto measurement interval of 5 seconds or 2 minutes for data recording.

Recording Altitude Readings:

Altitude data can be recorded manually, automatically, or as climb records. Manual records store altitude, date, and time (up to 30 records). Auto records store high/low altitude and cumulative ascent/descent. Climb records are similar but continue even if you exit the Altimeter Mode (up to 14 records).

Specifying the Altitude Measurement Unit: You can select meters (m) or feet (ft) for altitude display, unless Tokyo is set as the Home City, which fixes it to meters.

Altitude Reading Precautions: Maintain stable temperature for readings. Avoid activities with sudden altitude changes. Aircraft cabin pressure differs from outside altitude.

Barometric Pressure and Temperature Measurement

This feature allows you to take barometric pressure and temperature readings.

Measuring Barometric Pressure and Temperature:

Enter the Barometer/Temperature Mode. The watch displays current pressure, temperature, and a pressure graph. It takes readings every five seconds for three minutes, then every two minutes.

Checking Changes in Barometric Pressure Over Time:

View a graph of barometric pressure readings taken at two-hour intervals for the past 42 hours to predict weather trends.

Checking the Change Between Two Barometric Pressure Readings (Barometric Pressure Differential):

The display shows the current pressure and the differential from the last reading. This can indicate weather changes.

Sudden Barometric Pressure Change Indications:

The watch alerts you with beeps and an arrow indicator for significant pressure changes, potentially indicating weather shifts or altitude changes.

Correcting Measured Barometric Pressure and Temperature Values (Offset):

You can adjust pressure and temperature readings if major errors are noticed. Ensure the watch is at a stable temperature before adjusting the temperature sensor.

Specifying the Barometric Pressure Unit: Choose between hectopascals (hPa) or inches of mercury (inHg).

Specifying the Temperature Measurement Unit: Choose between Celsius (°C) or Fahrenheit (°F).

Barometric Pressure and Temperature Reading Precautions: Use as a weather trend indicator, not a precision instrument. Temperature readings can be affected by body heat, sunlight, and humidity; remove the watch for accurate readings. Pressure readings can be affected by temperature changes.
