Power Supply

The power supply of this watch uses a solar cell to generate
electrical power, which is stored by a rechargeable battery. Using
or storing the watch where it is not regularly exposed to light, or
allowing it to be blocked from light by your sleeve for long periods
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 when you
are wearing or storing it.
Important!
Note that all data in memory and all settings are cleared whenever
you allow the level of the rechargeable battery to drop to Level 4.
❚ Checking the Battery Level
Use the Battery Level Screen to check the current level of the
watch's rechargeable battery.
• In the Timekeeping Mode, press the C button once to change to
the Battery Level Screen.

• Exposing the watch to direct sunlight or other strong light may
cause the battery level indicator to momentarily indicate a level
that is higher than the actual battery level. Because of this, you
should wait for a short while after charging to check the battery
level indicator.
• Alarms and the hourly time signal cannot be turned on, and signal
reception is disabled while the battery is at Level 3.
• Signal reception will become enabled again when the battery is
recharged up to Level 2.
• Even after the battery drops to Level 4, watch operation will
resume as soon as charging starts. However, you should wait until
the digital display operation resumes before setting the time and
date.
• The display will automatically revert to the Timekeeping screen if you leave the Battery Level, Alarm, or Hand Setting screen displayed
without performing any operation for about two or three minutes.

❚ Charging Precautions

Avoid charging the watch in the following locations, and anywhere
else where the watch may become very hot.
• On the dashboard of an automobile parked in the sun
• Very close to an incandescent light source or other sources of
heat
• In 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 during
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.
• Remember that even a partial blockage of the solar cell reduces
charging efficiency.
Example: Positioning the watch
