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-13). Continue exposing
the watch to light until the battery power indicator shows H or M.
Time Calibration Signal
The information in this section applies only when LIS, LON, MAD, PAR, ROM,
BER, STO, ATH, MOW, HKG, BJS, HNL, ANC, YVR, LAX, YEA, DEN, MEX, CHI,
NYC, YHZ, YYT, SEL, or TYO is selected at the Home City. You need to adjust the
current time manually when any other city is selected as the Home City.
E-80
■ The current time setting changes after I set it manually.
You may have the watch configured for Auto Receive of the time calibration signal
(page E-26), 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-40).
■ The current time setting is off by one hour.
Possible Cause Remedy

Watches that do not have WATER RESIST or WATER RESISTANT marked on the
back cover are not protected against the effects of sweat. Avoid using such a watch
under conditions where it will be exposed to large amounts of sweat or moisture, or
to direct splashing with water.
Even if a watch is water resistant, note the usage precautions described below.
Such types of use reduce water resistance performance and can cause fogging of
the glass.
− Do not operate the crown or buttons while your watch is submersed in water or
wet.
− Avoid wearing your watch while in the bath.
− Do not wear your watch while in a heated swimming pool, sauna, or any other high
temperature/high humidity environment.
− Do not wear your watch while washing your hands or face, while doing housework,
or while performing any other task that involves soaps or detergents.
After submersion in seawater, use plain water to rinse all salt and dirt from your
watch.
To maintain water resistance, have the gaskets of your watch replaced periodically
(about once every two or three years).
