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

3. BEFORE USING
When the watch does not operate according to the handling instruction, it is
insufficiently charged. Charge the secondary battery of the watch for more than 6
hours, approximately 20 cm away from the fluorescent lamp or incandescent lamp as
light sources.
When charging the secondary battery, do not pull it too close to the light source.
* When charging the watch under direct rays of the sun, charge more than an hour.
An Eco Drive Rechargeable battery is used in this watch to store electrical energy.
This rechargeable 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
measurement 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 over-charging this watch. (Over-Charging Prevention
Functions is included) We recommend that you recharge the watch everyday.
4. SPECIAL FUNCTIONS OF THE SOLAR POWER WATCH
If this watch becomes insufficiently charged, a warning function comes into
operation and the display changes, as below.

Insufficient Recharging Warning Function (Refer to section "Insufficient
Charge and Time Setting Warnings")
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 A 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.
Stop Warning Function (Refer to section "Insufficient Charge and Time
Setting Warnings")
If the watch is left intact in the undercharged state, about 5 days later the second
hand will move to the A 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 function stop.
Hands Setting Warning Function (Refer to section "Insufficient Charge and
Time Setting Warnings")
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.
(Hands setting warning display)
* The hours, minute and 24-hour hands run at the incorrect time.
Over-Charging Prevention Function
You can recharge without worry. When the rechargeable battery is fully
recharged, the over-charging prevention function works so that the rechargeable
battery is not overcharged.
5. NOTES ON USE
/!\ Warning
Never use a battery other than the Eco Drive Rechargeable battery.
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 oxide battery, there is a
danger that the watch will be overcharged to burst, causing damage to the
watch and even to the human body.

* The watch will be damaged during recharging if it gets too hot (Over
60'C/140'F).
Avoid recharging at high temperatures (Over 60oC/140oF).
(eg)Charging the watch near a light source that easily become hot, such as
an incandescent lamp or a halogen lamp.
Charging in a place that easily becomes hot, such as a dashboard.
7. TIME REQUIRED FOR RECHARGE

5) TIME SETTING AND RECHARGE WARNINGS
When shown the insufficient charge warning display
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 modes to the ^CHARGE position,
indicating insufficiently charged. In
such a case, expose the watch to
sufficient light for the warning state
to be cancelled. (The second hand
return to 1 second movement)
It takes about 30 minutes from starting
to expose the watch to light until this
warning state is cancelled. The
charging time varies depending on the
light (light source) that radiates over
the watch.
When shown the stop warning display If the watch is left intact in the
undercharged state, about 5 days later
the second hand move to the ^STOP
position, indicating that the watch has
stopped due to insufficient recharge.
* All function are stopped in this state.
In such a case, expose the watch to
sufficient light for the warning state to
be cancelled.
After carrying out sufficient
charging, it is necessary to reset
the alarm time.
When shown the hands setting warning display
If you expose a watch which has stopped
once to light and recharge it, the second
hand will move to the ^SET position to let
you know that the time is incorrect.
In such a case, readjust the hour, minute
and 24- hour hands to keep correct time.
Without adjusting the time hands after the
watch is fully recharged, you cannot use
such function as alarm, chronograph, etc.
properly.
Be careful because if the watch is not
sufficiently charged during the Hands
Setting Warning Display State, and if
light is blocked from it, the second hand
will change to the ^STOP position and the
watch will stop running.
