Operation Guide 2514/2645

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 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.

Important!

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.

Charging Precautions

Avoid charging the watch in the following locations, and anywhere else the watch may become very hot.

•On the dashboard of an automobile parked in the sun

•Very close to an incandescent light source or other sources of heat

•In a location exposed to direct sunlight for long periods

Note that the display panel may become black under very high temperatures. This is temporary, and the display will appear normal again at lower temperatures.

❚Charging Guide

Starting from a full charge, it should take approximately six months of operation without further charging under the conditions described below before battery drops to Level 3.

Battery Indicator

•Even after the battery drops to Level 4, watch operation will resume as soon as charging starts. However, you should wait until the battery reaches Level 2 before setting the time and date.

❚Start charging at Level 3!

If the Level 3 indicator starts to flash, it means that battery power is very low. Be sure to expose the watch to light for recharging as soon as possible after the Level 3 indicator starts to flash.

Depending on the light source you are using, the case of the watch may become quite hot during charging. Take care to guard against burn injury after charging.

❚To charge the battery

Point the solar panel (face) of the watch at a light source.

•Exposing the watch to direct sunlight or other strong light may cause the battery level indicator to momentarily indicate a level that is higher than the actual battery level. Because of this, you should wait for a short while after charging to check the battery level indicator.

❚RECOVER Indicator

If you use the light or alarms a number of times during a short period, the RECOVER indicator may appear on the display to indicate that the following operations are disabled in order to allow battery power to recover.

• Alarm and hourly time signal

• Time calibration signal reception

Normal operation will return after the battery recovers.

•Remember that even a partial blockage of the solar cell reduced charging efficiency.
