Congratulations upon your selection of this CASIO watch.
Applications
The built-in sensors of this watch measure direction, barometric pressure, temperature, and water depth.
Measured values are then shown on the display. Such features make this watch useful when diving or
when engaging in other such outdoor activities.
The measurement functions built into this watch are not intended for taking measurements that
require professional or industrial precision. Values produced by this watch should be considered
as reasonable representations only.
When engaging in diving or other activities in which losing your way can create a dangerous or
life-threatening situation, always use a second underwater compass to confi rm direction readings.
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.

2. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under "To confi gure Home City and summer time settings" (page E-30) to confi gure your
Home City and daylight saving time settings.
Important!
Proper time calibration signal reception, and World Time Mode data depend on correct Home City,
time, and date settings in the Timekeeping Mode. Make sure you confi gure these settings correctly.
3. Set the current time.
To set the time using a time calibration signal
See "To get ready for a receive operation" (page E-16).
To set the time manually
See "Confi guring Current Time and Date Settings Manually" (page E-32).
The watch is now ready for use.
For details about the watch's radio controlled timekeeping feature, see "Radio Controlled Atomic
Timekeeping" (page E-14).

Operation Guide 3445
Warning !
Important!
The watch's water depth measurement function is intended to be used as a backup depth gauge.
Whenever you use the digital compass of this watch for serious diving or other activities, be sure to
always take along another underwater compass to confi rm readings. If the readings produced by the
digital compass of this watch are different from those of the other compass, perform directional
calibration of the digital compass to ensure more accurate readings.
Direction readings and digital compass calibration will not be possible if the watch is in the vicinity of a
permanent magnet (magnetic accessory, etc.), metal objects, high-voltage wires, aerial wires, or
electrical household appliances (TV, computer, cellphone, etc.)
Things to check before using the watch
1. Check the battery power level.
Is "H" or "M" displayed for the battery power indicator (page E-10)?
NO
Does any one of the following conditions exist?
Battery power indicator shows "L" and "LOW" is fl ashing on the
display.
"CHG" is fl ashing on the display.
The face is blank.
YES
Power is low. Charge the watch by placing it in a location
where it is exposed to light. For details, see "Charging the
Watch" (page E-9).
