Module No. 5682

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!

Some light sources and environments can cause the watch to become extremely hot during charging, which creates the risk of burn injury and damage to internal watch components.
Avoid charging the watch under conditions like the ones described below, where the temperatures may exceed 60 °C (140 °F).

On the dashboard of a vehicle parked in the sun

Near incandescent lamps, camera lights, halogen lamps, or other sources of heat

In locations exposed to direct sunlight for long periods and other hot locations

The display panel may become black (or white, depending on the LCD type) under very high temperatures. This is temporary, and the display will return to normal at lower temperatures.

Checking the Charge Level

A display indicator shows the watch’s charge level when you enter the Timekeeping Mode.

Charge Level 5: Dead

All hands are stopped and digital displays are blank. 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.

Note

If [RECOVER] is flashing on the display, it means that all functions are disabled due to momentary battery power consumption.

Exposing the watch face to light after the battery goes dead causes the [CHARGE] indicator to appear. This indicates charging has started.

Power Saving Function

Leaving the watch in a dark location for about one hour between the hours of 10 p.m. and 6 a.m. will cause the display to go blank, and the watch to enter Level 1 power saving. If the watch is left in this condition for six or seven days, the watch will enter Level 2 power saving.

Power Saving Level 1:

The second hand stops at 12 o’clock and the digital display goes blank to save power.

Power Saving Level 2:

All hands stop and the digital display goes blank to save power. All functions are disabled.
