Important!

• Keep the watch’s face exposed to light as much as possible (page E-4).
• This manual provides a brief overview of your watch.

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 ue of 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 is available on the CASIO website.

WAVE CEPTOR Important!

Before using the watch for the first time, use the steps below for signal reception, which sets the current time. See the Operation Guide available on the CASIO website for details.

1. Specify your Home City code (time zone where you normally use the watch).
2. Perform manual signal receive.

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 the second hand to stop.
• Leaving the watch in a dark location for about one week will cause all hands to stop.

Battery Alerts

• Low Battery
  Second-hand jumps every two seconds (Low Battery Alert).

• Dead Battery
  All hands stopped.

Using the Watch

Navigating Between the Timekeeping, Compass, and Altimeter Modes

• To return directly to the Timekeeping Mode from any other mode, hold down B for at least two seconds.
• To enter the Compass Mode or Altimeter Mode from any mode not shown in the diagram below, first, return to the Timekeeping Mode.

Navigating to Other Modes

Configuring Current Time and Date Settings Automatically

Date and time settings are kept accurate using the information provided by a time calibration signal.

• Time calibration signals can be received using Auto Receive (page E-11) or Manual Receive. Normally, you should set up the watch for Auto Receive of the current time and date.
• If you are in an area where a time calibration signal cannot be received, you need to adjust time and date settings manually (page E-13).
• For information about manual receive and time calibration signal reception ranges, refer to the Operation Guide available on the CASIO website.

Important!

• For the watch to be able to receive a time calibration signal, its Home City setting must be one where time calibration signal reception is normally supported (pages E-11 and E-12).

Cities where Time Calibration Signal Reception is Supported
TOKYO (TYO): Japan
HONG KONG (HKG): China
NEW YORK (NYC), CHICAGO (CHI), DENVER (DEN), LOS ANGELES (LAX), ANCHORAGE (ANC),
HONOLULU (HNL): United States
LONDON (LON), PARIS (PAR), ATHENS (ATH): United Kingdom, Germany

• The areas covered by ANCHORAGE (ANC) and HONOLULU (HNL) are quite far from the calibration signal transmitters, so certain conditions may cause reception problems.
  Auto Receive
  Important!

  • Perform the signal receive operation in the Timekeeping Mode.
    See “Using the Watch” (page E-6).

● Leave the watch near a window between midnight and 5:00 a.m.

• When the receive operation is successful, the time and date settings will be adjusted automatically.
• If you are unable to receive a signal, check the Operation Guide available on the CASIO website to ensure the watch is in a suitable location.

Mode Settings

• Before performing a crown operation, rotate it towards you to unlock (unscrew) it.
• You can change the following settings by operating the watch’s crown: Home City, Start time (Timer), Alarm time, and World Time City.
• For full details about mode operations and calibrating measurements (direction, altitude, barometric pressure, temperature), refer to the Operation Guide available on the CASIO website.

Important!

• When not using the crown, be sure to rotate it away from you to relock it (screw it back in). This protects against damage due to impact and loss of water resistance.

Changing the Current Time and Date Settings Manually

1. Timekeeping Mode: Unscrew crown. → Pull it out.
2. Press D. → Press B to cycle between settings.
   • Push the crown back in when done.

• Operation details: Operation Guide is available on the CASIO website.
