■ 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.
The watch is recovering from a sleep state (page E-16).
The time setting is being adjusted following a successful auto time calibration
signal receive operation (page E-17).
The watch is returning to the Timekeeping Mode automatically from the Alarm Mode
(page E-54).
■ Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode (page E-13). 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.

World Time Mode
■ The World Time indicated by the b Left Dial Hands in the World Time Mode is
one hour off from the actual time in the selected time zone.
The STD (standard time)/DST (daylight saving time) setting of the selected World
Time City may be wrong. Select the correct STD (standard time)/DST (daylight saving
time) setting (page E-49).
■ The World Time indicated by the b Left Dial Hands in the World Time Mode
is off.
Your Home City setting may be wrong. Check your Home City setting and correct it, if
necessary (page E-33).
Charging
■ The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 3 (page E-12). Continue
exposing the watch to light until the x Second Hand starts moving normally (at one-
second intervals).
E-66
■ The x Second Hand indicates N (NO) when I check the result of the latest
receive operation.

Troubleshooting

Hand Movement and Position
■ I lost track of what mode the watch is in.
Refer to "To select a mode" (page E-31). To return directly to the Timekeeping Mode
from any other mode, hold down C for about two seconds.
■ The x Second Hand is moving at two-second intervals.
■ All the watch's hands are stopped at 12 o'clock and none of the buttons work.
Power may be low. Expose the watch to light until the x Second Hand starts moving
normally, at one-second intervals (page E-11).
■ The current time setting is off by hours.
Your Home City setting may be wrong. Check your Home City setting and correct it, if
necessary (page E-33).
■ The current time setting is off by one hour.
If you are using the watch in an area where time calibration signal reception is
possible, see "To confi gure Home City settings" (page E-33).
If you are using in the watch in an area where time calibration signal reception is
not possible, you may need to change your Home City's STD (standard time)/DST
(daylight saving time) setting manually. Use the procedure under "To toggle the Home
City time between standard time and daylight saving time" (page E-35) to change the
STD/DST setting.
■ The hands and/or day indications are off.
This could indicate that the watch has been exposed to magnetism or strong impact,
which has caused problems with proper hand and day alignment. Adjust the watch's
hand and day home position alignment (page E-55).
■ The x Second Hand starts to move at one-second intervals, but then suddenly
returns to moving at two-second intervals.
The watch probably is not suffi ciently charged yet. Continue keeping it exposed to
light.
Time Calibration Signal
The information in this section applies only when LON (LONDON), PAR (PARIS),
ATH (ATHENS), HNL (HONOLULU), ANC (ANCHORAGE), LAX (LOS ANGELES),
DEN (DENVER), CHI (CHICAGO), NYC (NEW YORK), HKG (HONG KONG), or TYO
(TOKYO) is selected as the Home City. You need to adjust the current time manually
when any other city is selected as the Home City.
■ The current time setting changes after I set it manually.
You may have the watch confi gured for Auto Receive of the time calibration signal
(page E-24), which will cause the time to be adjusted automatically according to your
currently selected Home City. If this results in the wrong time setting, check your
Home City setting and correct it, if necessary (page E-33).
■ The current time setting is off by one hour.
Possible Cause Remedy
Perform the operation under "To get ready
for a receive operation". The time setting
will be adjusted automatically as soon as
