MA0410-EA

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.

❚

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

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.

•

Even after the battery drops to the level that timekeeping becomes disabled, you will be able to
resume normal operation by charging the battery.

•

After timekeeping becomes disabled, the hands will move to the current time after the battery is
recharged sufficiently.

•

Keep the watch exposed to light until normal operation returns.

❚

Point the solar cell (face) of the watch at a light source to
charge the battery.

•

Remember that even a partial blockage of the solar cell
reduces charging efficiency.

 The following is the daily amount 

of charging required each day to 
support the operations under 
“Daily Use”. 

Power Saving puts the watch into a sleep state, which will cause the second hand to stop moving
whenever the watch is left in the dark.

•

Note that hand movement may stop if the watch is blocked from light by your sleeve.

❚

The second hand stops whenever the watch is left in the dark for about 60 or 70 minutes between the
hours of 10:00 p.m. and 6:00 a.m. Time calibration reception continues to be performed at this time.
If the watch is left in the dark for an additional seven or eight days, the hour and minute hand also
stop. Time calibration is not performed while the hour and minute hands are not moving.

•

Timekeeping continues internally even when the hands are stopped.

❚

Move the watch to a brightly lit location or press any button, and the hands will move to the current
time setting and resume timekeeping from there.
