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.
IMPORTANT

■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.
■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

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.
7
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”.

■NOTES ON CHARGING
NOTE
•The watch will be damaged during recharging if it gets too hot (over
60°C/140°F). Avoid recharging at high temperatures.
(eg) Charging the watch near a light source that easily becomes hot, such
as an incandescent lamp or a halogen lamp.
Charging in a place that easily becomes hot, such as a dashboard.
•Note that full charging is difficult in a place irradiated by only weak light.
•When you charge the watch by an incandescent lamp, take a distance
about 50cm (20in.) from the light source to prevent extremely high
temperature.
9
■NOTES ON USE
Please take care to charge your watch during use.
Please note that if you wear long sleeves, the watch can easily become
insufficiently charged because it is hidden and not exposed to light.
•When you take off the watch, try to place it in as bright a place as
possible, and it will always continue to run properly.
CAUTION
Never use another battery apart from the secondary battery (Titanium
Lithium Ion Battery) used in this watch.
The watch structure is so designed that a different kind of battery other than
the specified cannot be used to operate it. However, in case a different kind
of battery such as a silver battery is used by some chance, there is a danger
that the watch will be overcharged to burst, causing damage to the watch
and even to the human body.
When you replace the secondary battery, be sure to use a designated
secondary battery.
