Operation Guide 5089
 ■ ■ The current time setting changes after I set it manually.
You may have the watch configured for Auto Receive of the time calibration signal,
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.
 ■ ■ The current time setting is off by one hour.
Possible Cause Remedy
Signal reception on a day for switching
between STD (standard time)/DST
(daylight saving/summer time) may have
failed for some reason.
Perform the operation under “To get ready
for a receive operation”. The time setting will
be adjusted automatically as soon as signal
reception is successful.
If you are unable to receive the time calibration
signal, change the STD (standard time)/DST
(daylight saving/summer time) setting manually.
 ■ ■ Auto Receive is not performed or I cannot perform Manual Receive.
Possible Cause Remedy
The watch is in the Stopwatch Mode.
Auto Receive is not performed while the watch
is in the Stopwatch Mode. Hold down C for
about two seconds to enter the Timekeeping
Mode.
Your Home City setting is wrong.
Check your Home City setting and correct it,
if necessary.
There is not enough power for signal
reception.
Expose the watch to light to charge it.
 ■ ■ Signal reception is being performed successfully, but the time and/or day is
wrong.
Possible Cause Remedy
Your Home City setting is wrong.
Check your Home City setting and correct it,
if necessary.
The watch may have 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
positions.
