C. FUNCTIONS OF SOLAR POWERED WATCH
■ Insufficient Charge Warning Function
The second hand changes to a
two second interval movement to
indicate insufficient charging.
Even in such a case, the watch
keeps correct time, but about 20
days after the two second
movement begins, the watch will
stop. After exposing the watch to
light, recharging takes place and the
watch returns to one second interval movement.
■ Quick Start Function
The watch will stop if it is completely discharged.
It will begin to operate soon after it is exposed
to light. (However, the time to start may vary
according to the brightness of the light.)
■ Time Setting Warning Function
If the watch stops, subsequent
exposure to light allows the Quick
Start Function to start again, and the
second hand moves with a hitch to
indicate that the time is incorrect.
■ Overcharge Prevention Function
You can recharge without worry.
Once the secondary battery is fully recharged, the
overcharging prevention feature comes into
operation and prevents over-recharging.
D. CARE AND HANDLING DURING CHARGING
■ Notes on use
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 the watch off, place it in as bright
a place as possible, and it will always continue to
run properly.
■ Notes on recharging
• Avoid recharging at high temperatures (over
about 60˚C/140˚F), otherwise the watch will be
damaged during recharging.
(eg) Charging the watch near a light source that
easily becomes hot, such as an incandescent
lamp or halogen lamp.
Charging in a place that easily becomes hot,
such as a dashboard.
When you charge the watch by an incandescent
lamp, take a distance about 50cm (20in.) from the
light source to prevent extremely high temperature,
E. REPLACING THE SECONDARY BATTERY
Unlike ordinary batteries, the secondary battery
used in this watch doesn’t have to be periodically
replaced due to repeated charging and discharging.
CAUTION
Never use another battery different from the
secondary battery used in this watch.
The watch structure is so designed that a different
kind of battery other than that specified cannot be
used to operate it. In case a different kind of battery
such as a silver battery is used by some chance,
there is a danger that it will be overcharged to
burst, causing damage to the watch and even to
the human body.
F. TIME REQUIRED FOR CHARGING
The time required for charging may vary according
to the caliber number, design (colour of the dial,
etc) and operating environment. The following table
will serve as a rough reference.
*The recharging time is the time when the watch is
continuously exposed to radiation.
Please check the caliber number on the caseback
Full recharging time (Empty to full)...
The time for fully recharge from stopped.
One day usage...
The time required for the watch to run for one day
with one second interval movement.
