charging. Take care to guard against burn injury
after charging.
Example: Positioning the watch
■ 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.
■ 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.
■ Flashing Recover Indicator
If you use the light or alarm a number of times during a short
period, a recover (R) indicator flashes on the display and the

Power Supply
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.
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.
■ Checking the Battery Level
Use the Battery Level Screen to check the current level of the
watch’s rechargeable battery.
