Operation Guide 5088
■ 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,
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
Signal reception on a day for switching
between STD (standard time)/DST (daylight
saving time) may have failed for some
reason.
■ Auto Receive is not performed or I cannot perform Manual Receive.
Possible Cause
The watch is in the Stopwatch Mode.
Your Home City setting is wrong.
There is not enough power for signal
reception.
■ Signal reception is being performed successfully, but the time and/or day is
wrong.
Possible Cause
Your Home City setting is wrong.
The watch may have been exposed to
magnetism or strong impact, which has
caused problems with proper hand and day
alignment.
