■ Signal reception is being performed successfully, but the time is wrong.
Possible Cause Remedy Page
Your location setting is wrong.
Check your location setting and correct
it, if necessary.
E-27
The watch may have been exposed
to magnetism or strong impact, which
has caused problems with proper hand
alignment.
Adjust the watch’s hand home positions. E-34
E-44
■ 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-21), which will cause the time to be adjusted automatically according to your
currently selected location. If this results in the wrong time setting, check your location
setting and correct it, if necessary (page E-27).
■ Auto Receive is not performed or I cannot perform Manual Receive.
Possible Cause Remedy Page
Your location setting is wrong.
Check your location setting and correct
it, if necessary.
E-27
There is not enough power for signal
reception.
Expose the watch to light to charge it. E-9
E-43
■ The
x
Second Hand indicates NO (N) when I check the result of the latest
receive operation.
Possible Cause Remedy Page
You are wearing or moving the watch, x
or performing a button operation
during the signal receive operation.
The watch is in an area with poor
x
reception conditions.
Keep the watch in an area where
reception conditions are good while
the signal receive operation is being
performed.
E-19
You are in an area where signal
reception is not possible for some
reason.
See “Approximate Reception Ranges”. E-17
The calibration signal is not being
transmitted for some reason.
Check the website of the organization x
that maintains the time calibration
signal in your area for information
about its down times.
Try again later.

■ 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 HONG KONG (HKG) or TOKYO
(TYO) is selected as the current location. You need to adjust the current time
manually when OFF is selected as the current location.
E-41
■ The current time setting is off by hours.
Your location setting may be wrong. Check your location setting and correct it, if
necessary (page E-27).
■ The hands are off.
This could indicate that the watch has been exposed to magnetism or strong impact,
which has caused problems with proper hand alignment. Adjust the watch’s hand
home position alignment (page E-34).
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).

Troubleshooting
Hand Movement and Position
■ The
x
Second Hand is moving at two second intervals.
■ All regular timekeeping hands are stopped at 12 o’clock, the
n
Minute Hand
(elapsed time) is at its home position (0), 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-12).
■ 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-15).
x
The time setting is being adjusted following a successful auto time calibration x
signal receive operation (page E-16).
