Normal operation enabled.
Signal reception, tones (alarms, hourly
time signal) display illumination, digital
display, and button operations disabled.
All functions, including digital
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, watch operation will
resume as soon as charging starts. However, you should wait until
the battery reaches Level 2 before setting the time and date.
❚
Start charging at Level 3!
If the Level 3 indicator starts to flash, it means that 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.
❚
RECOVER Indicator
If you use the light or alarms a number of times during a short
period, the RECOVER indicator may appear on the display to
indicate that the following operations are disabled in order to allow
battery power to recover.
• Display illumination
• Alarm and hourly time signal
• Time calibration signal reception
Normal operation will return after the
battery recovers.
Charging Precautions
Avoid charging the watch in the following locations, and anywhere
else 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 reduced
charging efficiency.
Example: Positioning the watch

• Note that the above charging times are for reference only. Actual
charging time depends on a variety of environmental factors.
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 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.
Important!
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.
