Congratulations upon your selection of this CASIO watch.
Applications
The built-in sensors of this watch measure direction, barometric pressure, temperature and altitude.
Measurement results are indicated by the second hand of the watch and on the digital 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.
• 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. Hold down
D
for about two seconds to enter the Timekeeping Mode, and then observe the
movement of the second hand.
Is the second hand moving smoothly at one-second intervals?
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
Is the second hand moving at two-second
intervals or is it stopped completely?
The watch is charged sufficiently. For details
about charging, see “Charging the Watch”
(page E-9).
NEXT
2. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under “To confi gure Home City settings” (page E-20) to confi gure your Home City and
daylight saving time settings.
Important!
Proper World Time Mode data depends on a correct Home City selection, and time and date settings in
the Timekeeping Mode. Take care that these settings are confi gured correctly.

3. Set the current time.
See “Confi guring Current Time and Date Settings” (page E-22).
The watch is now ready for use.
