Charging the Watch
While wearing the watch, take care so your sleeve does not block its face
(solar panel) from light. Charging effi ciency may be reduced if the face (solar
panel) is blocked from light, even partially.
When you are not wearing the watch, leave it where its face (solar panel) is
exposed to bright light for charging.
To help ensure stable operation, expose the face of the watch to about a half
day of direct sunlight each week to charge it.
Caution
The case of the watch may become extremely hot when charging. Guard against burn injury.
Important!
If the watch is not exposed to light for long periods, it will disable some functions and eventually stop
timekeeping.
The second hand will jump at two-second or fi ve-second intervals to indicate that battery power is low,
and stop completely when the battery is dead. Note that the watch also has a power saving function.
For details, see the Operation Guide available at the CASIO website.

Timekeeping (Current Time and Day Adjustment)
●
After purchasing the watch, perform the procedure under "Acquiring GPS Position Information"
(page E-12).
●
To set the current time and day, normally use the procedure under "Time Calibration Signal Auto
Receive" (page E-16). In areas where a time calibration signal cannot be received for some reason,
set the current time and day using the procedure under "GPS Signal Auto Receive" (page E-14).
Late night (between midnight and 5:00 a.m.): The receive operation starts at regular intervals until
Daytime (between 6:00 a.m. and 10:00 p.m.): The receive operation will start automatically when
Once a time calibration or GPS signal receive operation is successful, no more Auto Receive
operations are performed that day.
● ●
If the current time setting is not correct, perform the procedure under "Receiving GPS Time
Information" (page E-13).
●
If you move into another time zone, perform the procedure under "Acquiring GPS Position
Information". Next, perform one of the procedures under "Time Calibration Signal Auto
Receive", "GPS Signal Auto Receive", or "Receiving GPS Time Information" to set the current
time and day.
GPS and time calibration signal reception is not possible when the watch's temperature is less
than approximately –10°C (14°F) or greater than approximately 60°C (140°F).

the watch is continually expose to light (GPS).
Congratulations upon your selection of this CASIO watch.
Keep the watch's face exposed to light as much as possible (page E-4).
Do not try to remove the rechargeable battery from this watch. Always be sure to request rechargeable
battery replacement from your retailer. Use of a non-specifi ed battery type and/or incorrect
replacement creates the risk of burn injury and fi re due to explosion, overheating, combustion, etc.
Important!
For details about how to adjust the current time zone, time, and day settings, see "Timekeeping
(Current Time and Day Adjustment)" (Page E-6).

If timekeeping stops, you will need to expose the watch to light for a number of hours before it will
restart.
The watch will not charge if its temperature is –10°C (14°F ) or lower, or around 60°C (140°F ) or
higher.
If the watch is not charged for more than about three months after it stops running due to low power,
over-discharge will occur, which may make recharging impossible.
Even if you are unable to perform a GPS signal and/or time calibration signal receive operation for
some reason, the watch will keep time with average monthly accuracy of ±15 seconds.
Important!
If the current time and day setting is wrong after you perform one of the procedures under "Time
Calibration Signal Auto Receive", "GPS Signal Auto Receive", or "Receiving GPS Time Information", try
acquiring position information (GPS) and then perform the time/day setting procedure again.
If you feel that the current time and/or day indicator are not in the correct positions, you can adjust
their alignment. For details, see the Operation Guide available at the CASIO website.
Time calibration signal reception is normally possible in the areas below.
Japan, China, North America, Europe
For details, see the Operation Guide available at the CASIO website.
