Timekeeping (Current Time and Day Adjustment)
● Timekeeping is kept accurate using information provided by a time calibration signal and by
communication with a mobile phone.
xTime calibration signals can be received using Auto Receive or Manual Receive (page E-11).
xTo set the current time and day, normally use the procedure under “Time Calibration Signal Auto
Receive” (page E-12).
xFor information about how to adjust time using a phone, refer to the Operation Guide available at
the website below.
https://world.casio.com/manual/wat/
xTime calibration signal auto receive is not performed while the watch is able to connect with a
phone to adjust the watch time setting. Signal reception is performed whenever the watch is
unable to connect with a phone for time adjustment for more than one day.
xIf you are in an area where a time calibration signal cannot be received or if you cannot connect
with a phone for some reason, adjust time and date settings manually (page E-16).
Important!
xFor the watch to be able to receive a time calibration signal, its Home City setting must be one where
time calibration signal reception is normally supported (pages E-14 and L-2).
xIf 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.
xTime 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.
E-6
Charge Level Indication
xThe current charge level is temporarily indicated right after you enter the Timekeeping Mode.
See “Mode Reference Guide” (page E-8).
M: Good (medium)
H: Good (high)
L: Insufficient (low)
Battery Alerts
xLow Battery
Second hand jumps every two seconds (Low Battery Alert).
xDead Battery
All hands stopped.
E-5
Charging the Watch
xWhen you are not wearing the watch, leave it where its face (solar panel) is
exposed to bright light for charging.
xTo help ensure stable operation, expose the face of the watch to about a
half day of direct sunlight each month to charge it.
xWhile wearing the watch, take care so your sleeve does not block its face
(solar panel) from light. Charging efficiency may be reduced if the face (solar
panel) is blocked from light, even partially.
Caution
xThe case of the watch may become extremely hot when charging. Guard against burn injury.
Power Saving
xLeaving the watch in a dark location for about one hour between the hours of 10:00p.m. and
5:50a.m. will cause the second hand to stop at 12o’clock.
xLeaving the watch in a dark location for about one week will cause all hands to stop.

Appropriate Signal Reception Location (Time Calibration Signal)
xKeep the watch away from metal and position it so its 6 o’clock side is
facing a window. Avoid moving the watch as much as possible and do
not perform any watch operations while a signal receive operation is in
progress.
● You may experience time calibration signal reception problems in
the areas described below.
-Among or near buildings
-While riding in a vehicle
-Near household appliances, office machines, mobile phones, etc.
-On a construction site, in an airport, or any other location where radio
wave interference occurs
-Near high-voltage lines
-In mountainous areas or behind a mountain
xAlways check the time setting on the day there should be a switch
between standard time and summer time (DST). If the setting is not
correct (due to signal reception failure), turn DST on or off manually as
required.

Using the Watch in a Medical Facility or Aircraft
xDisable auto time adjustment whenever you are in a medical facility, and aircraft, in any other area
where radio wave reception and connection with a phone are prohibited or restricted.
