Timekeeping (Current Time and Day Adjustment)
● After purchasing the watch, perform the procedure under “Acquiring GPS Position Information”
(page E-9).
● To set the current time and day, normally use the procedure under “Time Calibration Signal Auto
Receive” (page E-13). 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-11).
xLate night (between midnight and 5:00 a.m.): The receive operation starts at regular intervals until
receive is successful (Time Calibration signal).
xDaytime (between 6:00 a.m. and 10:00 p.m.): The receive operation will start automatically when
the watch is continually expose to light (GPS).
xOnce 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-10).
● 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.
xGPS 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).
E-5
xIf timekeeping stops, you will need to expose the watch to light for anumber of hours before it will
restart.
xThe watch will not charge if its temperature is –10°C (14°F ) or lower, or around 60°C (140°F ) or
higher.
xIf 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.
E-4
Charging the Watch
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.
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 week to charge it.
Caution
xThe case of the watch may become extremely hot when charging. Guard against burn injury.
Important!
xIf the watch is not exposed to light for long periods, it will disable some functions and eventually stop
timekeeping.
xThe second hand will jump at two-second or five-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.
