MO1007-EC
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.
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.
About This Manual
Button operations are indicated using the letters shown in the
illustration.
Note that the product illustrations in this manual are intended for
reference only, and so the actual product may appear somewhat
different than depicted by an illustration.

Things to check before using the watch
1. Check the battery power level.
Is "H" or "M" displayed for the battery power indicator?
NO
Does any one of the following conditions exist?
Battery power indicator shows "L" and "LOW" is displayed in the
upper left corner of the screen.
"C" is displayed in the lower left corner of the screen.
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".
2. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under "To confi gure Home City settings" to confi gure your Home City and daylight
saving time settings.
Important!
Proper time calibration signal reception, and World Time Mode and Sunrise/Sunset 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".
To set the time manually
See "Confi guring Current Time and Date Settings Manually".
The watch is now ready for use.
For details about the watch's radio controlled timekeeping feature, see "Radio Controlled Atomic
Timekeeping".
Charging the Watch
The face of the watch is a solar cell that generates power from light. The generated power charges a
built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed
to light.
Charging Guide
Whenever you are not wearing the
watch, leave it in a location where it
is exposed to light.
Best charging performance is
achieved by exposing the watch to
the strongest light available.
Warning!
Leaving the watch in bright light for charging can cause it to become quite hot.
Take care when handling the watch to avoid burn injury. The watch can become particularly hot
when exposed to the following conditions for long periods.
On the dashboard of a car parked in direct sunlight
Too close to an incandescent lamp
Under direct sunlight
Important!
Allowing the watch to become very hot can cause its liquid crystal display to black out. The
appearance of the LCD should become normal again when the watch returns to a lower temperature.
Turn on the watch's Power Saving function and keep it in an area normally exposed to bright light when
storing it for long periods. This helps to ensure that power does not run down.
Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is
blocked from exposure to light can cause power to run down. Expose the watch to bright light
whenever possible.

Warning !

The watch is charged
sufficiently.
For details about
charging, see
"Charging the Watch".
Go to step 2.
When wearing the watch, make sure
that its face is not blocked from light
by the sleeve of your clothing.
The watch may enter a sleep state
if its face is blocked by your sleeve
even only partially.
Power Levels
You can get an idea of the watch's power level by observing the battery power indicator on the display.
Battery power
Battery power
indicator
indicator
The fl ashing LOW indicator at Level 3 (L) tells you that battery power is very low, and that exposure to
bright light for charging is required as soon as possible.
At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery
reaches Level 2 (M) after falling to Level 5, reconfi gure the current time, date, and other settings.
Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (M).
Leaving the watch exposed to direct sunlight or some other very strong light source can cause the
battery power indicator to show a reading temporarily that is higher than the actual battery level. The
correct battery level should be indicated after a few minutes.
All data stored in memory is deleted, and the current time and all other settings return to their initial
factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.
Power Recovery Mode
Performing multiple sensor, illumination, or beeper operations during a short period may cause all of
the battery power indicators (H, M, and L) to start fl ashing on the display. This indicates that the watch
is in the power recovery mode. Illumination, alarm, countdown timer alarm, hourly time signal, and
sensor operations will be disabled until battery power recovers.
Battery power will recover in about 15 minutes. At this time, the battery power indicators (H, M, L) will
stop fl ashing. This indicates that the functions listed above are enabled again.
If all of the battery power indicators (H, M, L) are fl ashing and the C (charge) indicator also is fl ashing,
it means the battery level is very low. Expose the watch to bright light as soon as possible.
Even if battery power is at Level 1 (H) or Level 2 (M), the Digital Compass Mode, Barometer/
Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available
to power it suffi ciently. This is indicated when all of the battery power indicators (H, M, L) are fl ashing.
Frequent fl ashing of all of the battery power indicators (H, M, L) probably means that remaining battery
power is low. Leave the watch in bright light to allow it to charge.

*1 Approximate amount of exposure time required each day to generate enough power for normal daily
operation.
*2 Approximate amount of exposure time (in hours) required to take power from one level to the next.
The above exposure times all are for reference only. Actual exposure times depend on lighting
conditions.
For details about the operating time and daily operating conditions, see the "Power Supply" section of
the Specifi cations.
Power Saving
When turned on, Power Saving enters a sleep state automatically whenever the watch is left for a certain
period in an area where it is dark. The table below shows how watch functions are affected by Power
Saving.
There actually are two sleep state levels: "display sleep" and "function sleep".
Elapsed Time in Dark
60 to 70 minutes (display sleep)
6 or 7 days (function sleep)
The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep
state when 6:00 AM arrives, however, it will remain in the sleep state.
The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode.
To recover from the sleep state
Move the watch to a well-lit area, press any button, or angle the watch towards your face for reading.
