Introduction

Congratulations upon your selection of this CASIO watch.

Important!

• This manual provides a brief overview of your watch.
• If you are going to a location where Internet access is not available, download the Operation Guide PDF from the website below to a device that you will be taking along with you.

Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss suffered by you or any third party arising through the use of your watch or its malfunction.

Important Altimeter and Compass Information

• The Altimeter Mode displays relative altitude based on barometric pressure readings. Readings taken at different times at the same location may produce different values due to changes in pressure. The value displayed by the watch may be different from the actual elevation and/or sea level elevation of your location.
• When using the Altimeter Mode for mountain climbing or other activities, it is highly recommended that you check a map, local altitude indications, or some other source for your current correct altitude, and that you regularly calibrate the Altimeter Mode.
• When using the watch compass for serious trekking or climbing, always take along another compass to confirm readings. If watch readings are different from the other compass, perform bidirectional calibration of the watch compass.
• Direction readings and calibration will not be possible if the watch is near a permanent magnet (magnetic accessory, etc.), metal objects, high-voltage wires, aerial wires, or electrical appliances (TV, computer, cellphone, etc.).
• Calibration: Operation Guide available at the CASIO website.

Charging the Watch

Remove the watch from your wrist and place it in a brightly lit area.

The watch may become hot when exposed to light for charging. Take care to avoid burn injury.

Avoid charging in locations where it is very hot.

Power Saving

• Leaving the watch in a dark location for about one hour between the hours of 10 p.m. and 6 a.m. will cause PS to flash on the display. All functions will continue operation.
• Leaving the watch in a dark location for about one week will cause PS to remain on the display without flashing. Only the timekeeping function will continue operation.

Battery Alerts

When battery power goes low, a warning message (LOW or CHG) appears on the display and certain functions become disabled. When a warning message appears, charge the watch as soon as possible.

Using the Watch

Navigating Between the Timekeeping, Compass, Barometer/Thermometer and Altimeter Modes

To return directly to the Timekeeping Mode from any other mode, hold down [Button D] for at least two seconds.

To enter the Compass, Barometer/Thermometer or Altimeter Mode from any mode not shown in the diagram below, first return to the Timekeeping Mode.

Timekeeping Mode

Changing the Current Time and Date Settings

1. In the Timekeeping Mode, hold down [Button E] for at least two seconds until the city code and city name starts to scroll.
2. Press [Button D] to move the flashing selection through the settings: City Code, DST (Daylight Saving Time), 12/24-Hour Format, Second, Hour, Minute, Year, Month, Day, Thermometer/Barometer/Altitude display unit, Power Saving, Illumination Duration, Button Operation Tone.
3. When the desired setting is flashing, use [Button A] (East) and [Button C] (West) or [Button A] (+) and [Button C] (-) to change the value as described:
   • Change City Code: Use [Button A] (East) and [Button C] (West).
   • Toggle DST: Press [Button A].
   • Toggle 12/24-Hour Format: Press [Button A].
   • Reset Second to 00: Press [Button A]. (If current seconds are 30-59, minute increments by one).
   • Change Hour or Minute: Use [Button A] (+) and [Button C] (-).
   • Change Year, Month, or Day: Use [Button A] (+) and [Button C] (-).
4. After all settings are correct, press [Button E] twice to exit the setting screen.
