E-18
If the time and date settings are incorrect
If the watch’s time and date settings are not correct after you fi nish performing the procedure above, it
could mean that the watch’s hands and/or date indicator positions are out of alignment. If this happens,
perform the home position adjustment procedure (page E-67).
x Note that an internal decoding process the watch performs after it receives a signal may cause the
time setting to be slightly off (by less than one second). Performing the home position adjustment
procedure does not correct this condition.
If time and date settings still are not correct, try performing the steps below.
Confi gure the Home City (Time Zone) setting (page E-59) and the summer time setting (page E-60).
Refer to the “City/Time Zone Indicators and Time Offset Table” (page L-2) to select your Home City
(Time Zone).
Use one of the procedures below.

Charging the Watch
The face of the watch is a solar panel that generates power from light. The generated power charges a
built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed
to light.
Important!
x This watch uses a special secondary battery.
− Charging will not be possible if the watch’s temperature is outside the approximate range of
approximately –10°C to 60°C (14°F to 140°F).
− Over-discharge will occur if the watch is not charged within approximately three months after it stops
operation due to low battery power. Charging may not be possible after over-discharge occurs. See
“Power Levels” (page E-24).
Charging Guide
Whenever you are not
wearing the watch, be sure
to leave it in a location where
it is exposed to light.
x Best charging
performance is achieved
by exposing the watch to
light that is as strong as
possible.
When wearing the watch, make
sure that its face is not blocked
from light by the sleeve of your
clothing.
x The watch may enter a sleep
state (page E-27) if its face is
blocked by your sleeve even
only partially.
Perform the GPS position information
acquisition operation again.
Note
x If the time and/or date setting is not correct even after you try performing the operations below, use
button and crown operations to confi gure time and date settings manually (page E-63).
− Change to another location and try performing a GPS signal and/or time calibration signal receive
operation again.
− Adjust the hand and day indicator home positions.
x Even in the above case, it is recommended that you move to a location that is appropriate for GPS
signal reception and perform a position information receive operation to confi gure time and date
settings.
x 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.
Warning!
Leaving the watch in bright light for charging can cause it to become quite hot. Take care when
handling the watch to avoid burn injury. The watch can become particularly hot when exposed to
the following conditions for long periods.
x On the dashboard of a car parked in direct sunlight
x Too close to an incandescent lamp
x Under direct sunlight
Important!
x Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps
to ensure that power does not run down.
x Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is
blocked from exposure to light can cause power to run down. Make sure that the watch is exposed to
bright light whenever possible.

■ The hands of the watch suddenly start moving at high speed, even when I do not perform any
operation.
This could be due to any one of the following causes. In all cases, the hand movement does not indicate
malfunction, and should stop shortly.
x The watch is recovering from a sleep state (page E-27).
x The time setting is being adjusted following a successful auto signal receive operation (page E-28).
■ Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode (page E-25). Do not perform any operation until the hands
return to their normal positions (in about 15 minutes). The hands should return to their correct positions when
normal operation returns. To help power recover, leave the watch in a location where it is exposed to light.
■ The current time setting is off by hours.
x Your Home City (Time Zone) setting may be wrong. Check your Home City (Time Zone) setting and
