Charging the Watch

The face of the watch is a solar cell that generates power from light. The generated
power charges a built-in rechargeable battery, which powers watch operations. The
watch charges whenever it is exposed to light.

Charging Guide

E-8

Whenever you are not
wearing the watch, leave
it in a location where it is
exposed to light.

Best charging

x

performance is achieved
by exposing the watch to
light that is as strong as
possible.

When wearing the watch,
make sure that its face is
not blocked from light by the
sleeve of your clothing.

The watch may enter a

x

sleep state (page E-14) if
its face is blocked by your
sleeve even only partially.

E-54 Troubleshooting

E-58 Specifi cations

Warning!
Leaving the watch in bright light for charging can cause it to become quite hot.
Take care when handling the watch to avoid burn injury. The watch can become
particularly hot when exposed to the following conditions for long periods.

x

On the dashboard of a car parked in direct sunlight
Too close to an incandescent lamp x
Under direct sunlight x

Important!

x

Keep the watch in an area normally exposed to bright light when storing it for long
periods. This helps to ensure that power does not run down.
Storing the watch for long periods in an area where there is no light or wearing it in x
such a way that it is blocked from exposure to light can cause power to run down.
Make sure that the watch is exposed to bright light whenever possible.

Power Levels

You can get an idea of the watch’s power level by
observing the movement of the x
Timekeeping Mode.

x

Second Hand is moving normally at one-second

If the
intervals, power is at Level 1.



If the

x

Second Hand is moving at two-second intervals,

power is at Level 2, which is quite low. Expose the watch
to light as soon as possible so it can charge.

Moves at two-second
intervals.

E-10

Power Recovery Mode

The watch is designed to go into a power recovery mode that stops hand operation
temporarily whenever power suddenly drops below a certain level due to overuse
of the alarm tone over a short period. Note that all operations are disabled while the
watch is in the power recovery mode.
The hands will move to the correct positions and the watch will resume normal
operation after power recovers (in about 15 minutes). Putting the watch in a location
where it is exposed to light will help power to recover sooner.

E-12

Power Saving

Power Saving enters a sleep state automatically whenever the watch is left for a
certain period in an area where it is dark. The table below shows how watch functions
are affected by Power Saving.

There actually are two sleep state levels: “second hand sleep” and “function sleep”.

x

Elapsed Time in Dark Operation

60 to 70 minutes (second hand sleep)

6 or 7 days (function sleep)

The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch x
is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep
state.
The watch will not enter a sleep state while it is in the Stopwatch Mode.

When power drops to Level 3, all functions will be disabled but the watch will x
continue to keep time internally for about one week. If you recharge the battery
suffi ciently during this period, the analog hands will move automatically to the
correct setting and regular timekeeping will resume. After one week, all settings
(including timekeeping) will be cleared. Recharging the battery will reset all settings
to their initial factory defaults.
