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.
x Time calibration signals can be received using Auto Receive or Manual Receive (page E-11).x To set the current time and day, normally use the procedure under “Time Calibration Signal Auto
Receive” (page E-12).
x For 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/
x Time 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.
x If 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!
x In order to make it possible for the current time setting to be adjusted correctly based on time
calibration signal reception, you need to specify the time zone where you are using the watch (pages
E-14 and L-2).
x 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.
x 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.

Charging the Watch
x When you are not wearing the watch, leave it where its face (solar panel) is
exposed to bright light for charging.
x To help ensure stable operation, expose the face of the watch to about a half
day of direct sunlight each month to charge it.
x While 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
x The case of the watch may become extremely hot when charging. Guard against burn injury.
Power Saving
x Leaving the watch in a dark location for about one hour between the hours of 9p.m. and 6a.m. will
cause the second hand to stop at 12o’clock.
x Leaving the watch in a dark location for about one week will cause all hands to stop.

Using the Watch in a Medical Facility or Aircraft
x Disable 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.
x Disabling auto time adjustment disables time calibration signal auto receive and auto connection with
a phone.
x Before using the crown, be sure to first read the “Crown Operations and Configuring Settings” (page
E-14).
x In the Calendar Mode, press B once and then pull out the crown to the first click. The second hand
will move to Y (YES) (auto receive enabled) or N (NO) (auto receive disabled). To disable auto time
adjustment, rotate the crown to move the second hand to N (NO). To enable auto time adjustment,
rotate the crown to move the second hand to Y (YES). After the setting is the way you want, push the
crown back in to its normal position.

Timekeeping (Based on a Time Calibration Signal)
Appropriate Signal Reception Location (Time Calibration Signal)
x Keep the watch away from metal and position it so its 12 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
x Always 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.
