The power supply of this watch uses a solar cell to generate
electrical power, which is stored by a rechargeable battery. Using
or storing the watch where it is not regularly exposed to light, or
allowing it to be blocked from light by your sleeve for long periods
as you are wearing it can cause the power of the rechargeable
battery to run down. To ensure stable operation, be sure to allow
the watch to be exposed to light as much as possible when you
are wearing or storing it.
Note that all data in memory and all settings are cleared
whenever you allow the level of the rechargeable battery
to drop to Level 4.
❚ Flashing RECOVER Indicator
If you use the light or alarms a number of times during a short
period, a RECOVER indicator flashes on the display and the
following operations become disabled as battery power recovers.
• Face illumination
• Alarm and hourly time signal
• Time calibration signal reception
Normal operation will return after the
battery recovers.
❚ Battery Level Screen

Digital display, face illumination,
alarms, tones (alarms, hourly time
signal), signal reception, and
analog timekeeping disabled.
All functions, including timekeeping,
disabled.
• Exposing the watch to direct sunlight or other strong light may cause
the battery level indicator to momentarily indicate a level that is higher
than the actual battery level. Because of this, you should wait for a
short while after charging to check the battery level indicator.
• Even after the battery drops to Level 4, you will be able to resume
normal operation by charging the battery.
• When charging from Level 4, the display will start operating when
the battery reaches Level 3. At this time you will be able to
configure digital time and date settings, but you should keep the
watch exposed to light until the battery reaches Level 2 or Level 1.
❚ Start charging at Level 3!
Battery Level 3 indicates that remaining battery power is very low.
Be sure to expose the watch to light for recharging as soon as
possible after the Level 3 indicator starts to flash.

Power Supply
An LED light is used to illuminate the face of the watch for easy
reading in the dark. An auto light switch automatically illuminates
the face when you angle the watch towards your eyes for reading.
❚ To illuminate the face manually
Press the L L L L L button in any
mode to illuminate the face of
the watch.
• You can use the procedure under
“To specify the illumination
duration” to configure the
illumination duration as
approximately 1.5 seconds or
2.5 seconds.
• Pressing the L button
illuminates the face regardless of
whether the auto light switch is
on or off.
You may hear a faint rattling sound when you move the watch
around. This sound is caused by the movement of a metal
bulb that controls operation of the auto light switch, and does
not indicate malfunction.
❚ To illuminate the face with the auto light
switch
The auto light switch automatically illuminates the face
whenever you angle the watch towards your eyes for reading,
but only when it is dark.
• The auto light switch does not illuminate the face when
surrounding light is bright.
You can use the procedure under “To specify the illumination
duration” to configure the illumination duration as
approximately 1.5 seconds or 2.5 seconds.
❚ To turn the auto light switch on and off
In any mode, hold down the L button for about two seconds to
toggle the auto light switch on (auto light switch on indicator
displayed) and off (no indicator displayed).

On Indicator
❚ Positioning Your Arm Correctly
• You should be wearing the watch on the outside of your wrist
when using the auto light switch.
• Make sure that the left (9 o’clock)
and right (3 o’clock) sides of the
watch are within
± 15 degrees of
being parallel with the ground.
The auto light switch may not
operate properly if the angle is
greater.
Important!
• The light may be difficult to see if you turn it on under bright
sunlight.
• If you press the L button or if an alarm operation starts while the
face is illuminated, illumination will turn off.
Auto Light Precautions
• Frequent use of the auto light can run down the battery.
• The auto light switch may cause the face to illuminate when your
sleeve covers the face of the watch.
• The face may not illuminate immediately when you angle the
watch towards your face. This does not indicate malfunction.
• The face remains illuminated for the currently set duration (1.5 or
2.5 seconds) only, even if you leave the watch angled towards
your face.
• The auto light switch is automatically disabled whenever battery
power is at Level 3 or lower.
• The face may illuminate unintentionally when you wear the watch
on the inside of your wrist, when you shake your arm, or when
you raise your arm. Be sure to turn off the auto light switch
whenever you do not need illumination.
• Keep the auto light switch turned off whenever you are wearing
the watch on the inside of your wrist.
• Electro-static charge and magnetism can interfere with auto light
operation and even make operation impossible. If this happens
lower your arm to the starting position and then raise it again. If
you still have trouble with illumination, try lowering your arm down
to your side and then raise it to your face for reading.
Rotate your arm so the watch
is angled at about 40 degrees,
so you can read its face. With the watch on
your wrist, position it
level with the ground.

❚ Charging Precautions
Avoid charging the watch in the following locations, and anywhere
else where the watch may become very hot.
• On the dashboard of an automobile parked in the sun
• Very close to an incandescent light source or other sources of
heat
• In a location exposed to direct sunlight for long periods
Note that the display panel may become black under very high
temperatures. This is temporary, and the display will appear
normal again at lower temperatures.
Depending on the light source you are using, the case
of the watch may become quite hot during charging.
Take care to guard against burn injury after charging.
❚ To charge the battery
Point the solar panel (face) of the watch at a light source.
• Remember that even a partial blockage of the solar cell reduces
charging efficiency.
