Congratulations upon your selection of this CASIO watch.
Applications
The built-in sensors of this watch measure direction, barometric pressure, temperature and altitude.
Measured values are then shown on the display. Such features make this watch useful when hiking,
mountain climbing, or when engaging in other such outdoor activities.
Warning !
• 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.
• The Moon phase indicator and tide graph data that appear on the display of this watch are not
intended for navigation purposes. Always use proper instruments and resources to obtain data for
navigation purposes.
• This watch is not an instrument for calculating low tide and high tide times. The tide graph of this
watch is intended to provide a reasonable approximation of tidal movements only.
• When engaging in mountain climbing or other activities in which losing your way can create a
dangerous or life-threatening situation, always use a second 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 this product or its malfunction.

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)?
Go to step 2.
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).
NO YES
YES
Does any one of the following conditions exist?
• Battery power indicator shows “
L
” and “
LOW
” is flashing on the
display.
• “
C
” is flashing on the display.
• The face is blank.
The watch is charged
sufficiently.
For details about

2. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under “To confi gure Home City settings” (page E-28) to confi gure your Home City and
daylight saving time settings.
Important!
Proper time calibration signal reception, and World Time Mode and Tide/Moon Data 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-31).
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).
