GPS Signal Auto Receive
Important!
Perform the signal receive operation in the Timekeeping Mode (not in the Airplane Mode). See "Mode
Reference Guide" (page E-10).
●
GPS signal time information is received automatically whenever all of the conditions described
below are satisfied.
- The current time is between 6:00 a.m. and 10:00 p.m.
- The face of the watch has been exposed continuously for about one or two minutes to light
equivalent to the brightness near a window on a clear day.
- All time calibration signal receive operations performed during the previous night were unsuccessful.

Time Calibration Signal Auto Receive
Important!
To perform time calibration signal auto receive, the watch must be in the Timekeeping Mode (not in the
Airplane Mode). See "Mode Reference Guide" (page E-10).
●
Leave the watch in a location that is appropriate for time calibration signal reception between
the hours of midnight and 5:00 a.m. See "Appropriate Signal Reception Location (Time
Calibration Signal)" (page E-17).
The second hand will point to RC while time calibration signal reception is in progress.
Reception normally takes anywhere from about two to ten minutes, but it can take as long as
20 minutes.
When the receive operation is successful, the time and day settings will be adjusted automatically.

Timekeeping (Based on a Time Calibration Signal)
Appropriate Signal Reception Location (Time Calibration Signal)
Keep 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
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.
Crown Operations and Configuring Settings
Before performing a crown operation, rotate it towards you to unlock (unscrew) it.
You can change the following settings by operating the watch's crown: World Time City (time zone),
Home City (time zone), summer time (DST), Timer, Alarms, and current time.
For details about crown operations, see the Operation Guide available at the CASIO website.

Important!
In order to prevent loss of water resistance and damage due to impact, make sure that the crown is
fully pushed in to its normal position when using the watch.
