Solar 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.

While you are wearing the watch, make sure that its face (solar panel) is not blocked from the 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.

• On the dashboard of a vehicle parked in the sun
  Near an incandescent light bulb or other source of heat
  Under direct sunlight or in other hot areas for long periods

● Low Battery

A low battery will cause [LOW] to flash and will disable the functions below.

• Time signal reception
- Illumination
- Sounds (alarms, etc.)
- Connection with a phone

If the charge level drops even further, [CHG] will flash. If this happens, all functions are disabled.

- 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. Keep the watch exposed to light until the current time appears on the display.

Note

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