Charging
■ The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 5 (page E-15). Keep the watch exposed to light until
it recharges suffi ciently.
■ RECOVER is fl ashing on the digital display.
The watch is in the charge recovery mode. Wait until the recovery process is complete (about 15 minutes).
The watch will recover more quickly if you place it in a brightly lit location.
Note
•
Performing repeated illumination and/or sensor reading operations over a short time period can cause
a sudden drop in watch’s charge. This will cause the watch to enter the charge recover mode. The
watch is in the charge recovery mode when RECOVER is fl ashing on the digital display. The charge
recovery mode is the same as a low battery charge state, access to some functions is limited while the
watch charge is recovering. Normal operation will resume after recovery is complete. For more
information, refer to “Power Recovery Mode” (page E-17).
•
A fl ashing CHARGE indicator means that the charge level of the watch has suddenly dropped.
Immediately expose the watch to light to charge it.
Time Calibration Signal
The information in this section applies only when LON, PAR, ATH, HKG, HNL, ANC, LAX, DEN, CHI,
NYC, or TYO is selected as the Home City. You need to adjust the current time manually when any other
city is selected as the Home City.
E-105
■ The display shows the ERR indicator when I check the result of the latest receive operation.
Possible Cause
Remedy
Page
•
You are wearing or moving the
watch, or performing a button
operation during the signal
receive operation.
•
The watch is in an area with
poor reception conditions.
Keep the watch in an area where reception conditions are good
while the signal receive operation is performed.
E-22
You are in an area where signal
reception is not possible for
some reason.
See “Approximate Reception Ranges”.
E-21
The calibration signal is not
being transmitted for some
reason.
•
Check the website of the organization that maintains the time
calibration signal in your area for information about its down times.
•
Try again later.
–
■ 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-23), 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-34).
E-106
■ The current time setting is off by one hour.
Possible Cause
Remedy
Page
Signal reception on a day for
switching between standard
time/daylight saving time (DST)
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.
E-22
If you are unable to receive the time calibration signal, change the
standard time/daylight saving time (DST) setting manually.
E-36
■ Auto receive is not performed or you cannot perform manual receive.
Possible Cause
Remedy
Page
The watch is not in the
Timekeeping Mode.
Auto receive is performed only while the watch is in the Timekeeping
Mode. Enter the Timekeeping Mode.
E-31
Your Home City setting is wrong. Check your Home City setting and correct it, if necessary.
E-34
There is not enough power for
signal reception.
Expose the watch to light to charge it.
E-14
E-107
■ Signal reception is being performed successfully, but the time and/or day is wrong.
Possible Cause
Remedy
Page
Your Home City setting is wrong. Check your Home City setting and correct it, if necessary.
E-34
The DST setting may be
incorrect.
Change the DST setting to Auto DST.
E-34
Calibration signal interference
caused the time and/or date
setting to be adjusted
incorrectly.
Perform manual calibration signal receive.
