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.
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.
