All functions disabled

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.
A short while after exposing the watch to light after its battery charge has run down

x

will cause the xx Second Hand to move counterclockwise until it stops at second 57
on the face. This indicates that charging has started. See page E-21 for information
about required charging times.

Power Levels

You can get an idea of the watch’s power level by
observing the movement of the

x

Second Hand in the

Timekeeping Mode.

If the

xx Second Hand is moving normally at one-second

intervals, power is at Level 1.
If the

xx 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.

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.

On the dashboard of a car parked in direct sunlight

x

Too close to an incandescent lamp x
Under direct sunlight x

Important!

Keep the watch in an area normally exposed to bright light when storing it for long

x

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.

E-16

Charging the Watch

The face of the watch is a solar panel 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

Whenever you are not
wearing the watch, be sure
to 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,
makes 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-22) if
its face is blocked by your
sleeve even only partially.

Split Pointer

The split pointer is marked on the

v

Mode Disk. Whenever you enter the Stopwatch

Split Mode (page E-46), it indicates the current status of the stopwatch operation.
While a normal stopwatch elapsed time measurement operation is in progress, the
split pointer will point to RUN. When a split time is indicated by the hands (which are
temporarily stopped), the split pointer will point to SPL. Stopping the elapsed time
measurement operation will cause the split pointer to move to STP (stop).

Lap Pointer

The lap pointer is marked on the

v

Mode Disk. Whenever you press B to perform

lap time measurement in the Stopwatch Mode, the

v

Mode Disk will rotate so the

lap pointer points at the current lap number (1 through 5). If the current lap number is
greater than 5, the lap pointer will point at

The vv Mode Disk uses three different pointers to indicate a variety of different
information: a mode pointer, a split pointer, and a lap pointer.

Mode Pointer

The mode pointer is in a fi xed position. Whenever you enter a mode, the v

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.
