Module No. 5658

Charging

This watch runs on power supplied from a rechargeable (secondary) battery that is charged by a solar panel. The solar panel is integrated into the face of the watch, and power is generated whenever the face is exposed to light.

Charging the Watch

When you are not wearing the watch, put it in a location where it is exposed to bright light.

WAT_SOLAR_01

While you are wearing the watch, make sure that its face (solar panel) is not blocked from light by the sleeve of your clothing. Power generation efficiency is reduced even when the face of the watch is blocked only partially.

Important!

Depending on light intensity and local conditions, the watch may become hot to the touch when exposed to light for charging. Take care to avoid burn injury after charging. Also, avoid charging the watch under high-temperature conditions like the ones described below.

Dead Battery

The digital display will go blank if the battery goes dead. Memory data is lost, and watch settings are returned to their initial factory defaults.

Important!

Should the battery go low or go dead, expose the face (solar panel) to light as soon as possible.

Exposing the watch to light while its battery is dead will cause [CHG] to start flashing. Expose the watch to light to charge it until the Timekeeping Mode screen re-appears.

Note

If [R] is flashing, it means that all functions, except for timekeeping, are disabled due to high momentary battery power consumption.
