Timekeeping (Current Time and Day Adjustment)
●
For information about how to adjust time using a phone, refer to the Operation Guide available
at the website below.
http://world.casio.com/manual/wat/
●
After purchasing the watch, perform the procedure under "Acquiring GPS Position Information"
(page E-14).
●
To set the current time and day, normally use the procedure under "Time Calibration Signal Auto
Receive" (page E-18). 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-16).
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-15).
●
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.

Using the Watch in an Aircraft (Airplane Mode)
Switch to the Airplane Mode whenever you are on an aircraft, or in any other location where signal
reception or connection with a phone is limited.
Entering the Airplane Mode disables GPS signal and time calibration signal reception, and connection
with a phone.
Before using the crown, be sure to first read the "Crown Operations and Configuring Settings" (page E-19).
While in the Timekeeping Mode, press B once and then pull out the crown to the first click. The
second hand will move to Y (YES) (receive enabled) or N (NO) (receive disabled). To enter the Airplane
Mode (receive disabled), rotate the crown to align the second hand with N (NO). To exit the Airplane
Mode (receive enabled), align the second hand with Y (YES). After the setting is the way you want,
push the crown back in to its normal position.

Performing a GPS Signal Receive Operation Manually
◆ Acquiring GPS Position Information
When position information is acquired successfully, the watch is able to determine its current location
and adjust its time and day setting accordingly.
Important!
Perform this operation in the Timekeeping Mode (not in the Airplane Mode). See "Mode Reference
Guide" (page E-10).
1. Move to a location appropriate for signal reception and orient the watch so its face is pointing straight
upwards.
See "Appropriate Signal Reception Location (GPS Signal)" (page E-13).
2. Hold down B until the second hand moves to T (TIME). Release
B after the second hand reaches T (TIME). Pressing B again will
cause the second hand to move to T+P and start location information
acquisition.
Position information reception takes anywhere from about
30 seconds to 80 seconds. It can take as long as 13 minutes.
Successful acquisition of position information will automatically
display the time and day for the resulting location.
Position information acquisition requires large amounts of power.
Perform the acquisition operation only when it is required.

Hold down for about 1.5 seconds to
start time information acquisition from
the GPS. Press again while reception
is in progress to acquire location
information from the GPS.
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.

Timekeeping (Based on GPS Signals)
Appropriate Signal Reception Location (GPS Signal)
When performing GPS signal reception, move the watch outside where there is a clear view of the sky
above, with no obstructing buildings, trees, or other objects.
GPS signal reception is not possible in the areas described below.
- Where the sky is not visible
- Underground or in a tunnel
- Indoors (Reception may be possible near a window.)
- Near wireless communication equipment or other devices that generate magnetism
◆ Receiving GPS Time Information
Perform this operation when you suspect that the time normally indicated by the watch is not correct.
If the GPS signal time information receive operation is successful, the watch will automatically adjust
the current time and day settings of the Home City (time zone).
Important!
Perform this operation in the Timekeeping Mode (not in the Airplane Mode). See "Mode Reference
Guide" (page E-10).

Note
If you experience signal reception problems, keep the
watch still and point its display straight up at the sky.
While a receive operation is being performed, take care
to avoid covering the watch face with your sleeve.
You may experience GPS signal reception problems in
the areas described below.
- Where the view of the sky above is narrow
- Near trees or buildings
- Near a train station, airport, or other congested areas
1. Move to a location appropriate for signal reception and orient the
watch so its display is pointed straight up at the sky. See "Appropriate
Signal Reception Location (GPS Signal)" (page E-13).
2. Hold down B until the second hand moves to T (TIME). Release
B after the second hand reaches T (TIME). This will start time info
reception.
Reception normally takes anywhere from six seconds to 60 seconds.
It can take as long as 13 minutes.
When the receive operation is successful, the watch will adjust its
current time and day settings automatically.
This operation requires large amounts of power. Perform it only
when necessary.
