Shifting the Hands

Hand shift moves the hands out of the way for easy viewing of display information.

1.While holding down (L), press (D).

●This will shift the analog hands to allow easy viewing of display information.

2.To return the hands to their normal timekeeping positions, hold down (L) as you press (D) again, or press (D) to change to another mode.

Note

●If you leave the watch with its hands shifted and do not perform any operation for about one hour, the hands will resume normal timekeeping automatically.

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 light by the sleeve of your clothing. Power generation efficiency is reduced even when the face of the watch is blocked only partially.

YES NO

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 hightemperature 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

● Checking the Charge Level

In the Timekeeping Mode, the current charge level is indicated by the mode hand.

A Good (high charge)

B Good (medium charge)

C Low Battery

● Remaining Charge and Dead Battery

You can determine if the charge level is low by checking the hand movement. Functions become disabled as battery power goes low.

Important!

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

Note

●Exposing the watch face to light after the battery goes dead will cause the [CHARGE] indicator to appear and the second hand to rotate counterclockwise until it stops at second 57. This indicates charging has started.

Low Battery Power

The second hand jumps at two-second intervals.

Second hand

Dead Battery

All hands are stopped.
