IMPORTANT

Before using

When the watch does not operate according to the instruction manual, it is insufficiently charged.

Charge the secondary battery of the watch for more than 6 hours, approximately 20cm (8in.) away from the fluorescent or incandescent lamp (30W) as light sources. When charging the secondary battery, do not put it too close to the light source.

*When charging the watch under direct rays of the sun, charge for more than an hour.

■ FEATURES

This watch is a multi-hands analog solar watch with alarm and chronograph functions, and a solar power function as its base which provides the power source for the watch's hands movement and alarm sound by converting solar energy into electrical power with the solar cell fitted on its face.

English

■ BEFORE USING

A secondary battery is used in this watch to store electrical energy. This secondary battery is a clean energy battery which doesn't use any toxic substances such as mercury. Once fully charged, the watch will continue to run for about 80 days (using the alarm sound for 15 seconds/day and the chronograph timer for 60 minutes/day) without further charging.

How to use this watch properly

For the comfortable use of this watch and its additional alarm and chronograph functions, take care to keep it sufficiently recharged.

There is no concern for overcharging this watch. (Overcharge Prevention
Function is included)
We recommend that you recharge the watch everyday.	1

Insufficient Charge Warning Function

If the watch is put in the undercharged state during any display mode, it switches to the time display when in other display modes, then the second hand moves to the ▲ CHARGE position, indicating the shortage of electricity. (Electric power shortage warning display) Even then, the time (hour, minute and 24-hour hands) runs accurately.

*The alarm does not ring even if it is set.

*If the chronograph is being used, measurement stops and it is reset.

*The push button does not function.

Refer to page 25, “■ In These Cases”.

Stop Warning Function

If the watch is left intact in the undercharged state, about 5 days later the second hand will move to the ▲ STOP position, indicating that the watch has stopped due to electric power shortage. (Stop warning display)

The other hands (hour, minute and 24-hour hands) also stop. * In this condition, all functions stop.

Refer to page 25, “■ In These Cases”.

Time Setting Warning Function

When the watch is recharged by exposing it to light after once stopped, the second hand moves to the ▲ SET position, indicating that the watch does not keep correct time. (Time setting warning display)

* The hour, minute and 24-hour hands run at the incorrect time.

Refer to page 25, “■ In These Cases”.

Overcharge Prevention Function

You can recharge without worry.

When the secondary battery is fully recharged, the overcharging prevention function works so that the secondary battery is not overcharged.
