Power Supply

The power supply of this watch uses a solar cell to generate electric power, which is stored by a rechargeable battery.

Using or storing the watch where it is not exposed to light regularly or allowing it to be blocked from light by your sleeve as you are wearing it can cause the power of the rechargeable battery to run down.

To ensure stable operation, be sure to allow the watch to be exposed to light as much as possible while you are wearing or storing it.

●Checking the Battery Level

Use the Battery Mode to check the current level of the watch’s rechargeable battery. ξIn the Timekeeping Mode, press C once to change to the Battery Mode.

ξThe battery level hand indicates the current battery level in all modes.

ξIndicators described to the left appear in the Timekeeping Mode at Level 3 and Level 4.

ξExposing the watch to direct sunlight or other strong light may cause the battery level hand to indicate a level that is momentarily higher than the actual battery level. Because of this, you should wait for a short while after charging to check the battery level.

ξEven if the battery level drops all the way to Level 5, you still will be able to recharge the battery and use the watch again.

ξIf you start charging from Level 5, the display of the watch will appear when the battery reaches Level 2. At this time you should continue to expose the watch to light until it charges up to Level 2 or Level 1.

ξThe Home City will revert to TYO (Tokyo) whenever the battery drops down to Level 5. If you are using a Home City setting that is not TYO (Tokyo), select the Home City you want after the battery is charged suffi ciently.

●Charging Precautions

Avoid charging the watch in the following locations, and anywhere else where the watch may become very hot.

ξOn the dashboard of an automobile parked in the sun

ξVery close to an incandescent light source or other sources of heat ξIn a location exposed to direct sunlight for long periods

Note that the display panel may become black under very high temperatures. This is temporary, and the display will appear normal again at lower temperatures.

Depending on the light source you are using, the case of the watch may become quite hot when charging. Take care to guard against burn injury after charging.

●To charge the battery

Point the solar panel (face) of the watch at a light source.

ξRemember that even partial blockage of the solar cell reduces charging effi ciency.
