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.
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.

•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.
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.

❚Flashing Recover Indicator
If you use the light or alarms a number of times during a short period, a RECOVER indicator flashes on the display and the following operations become disabled as battery power recovers.
• Display illumination, | RECOVER Indicator |
•Alarm and hourly time signal
•Time calibration signal reception
Normal operation will return after the battery recovers.
•“2696” and “2832” indicate module numbers.
•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.
•Even if the battery level drops all the way to Level 4, you will still be able to recharge the battery and use the watch again.
•When recharging from Level 4, set the current time and date after the battery level recharges to Level 3. At this time you should continue to expose the watch to light so it can charge up the Level 2 or Level 1.
❚Start charging at Level 3!
Battery Level 3 indicates that remaining 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.
Point the solar panel (display) of the watch at a light source.
•Remember that even a partial blockage of the solar cell reduces charging efficiency.

An EL (electro luminescent) panel is used to illuminate the display of the watch for easy reading in the dark. An auto light switch automatically illuminates the display when you angle the watch towards your face for reading.
❚To illuminate the display manually
When any screen besides a setting screen (one with a flashing setting), press the Bbutton to illuminate the display of the watch.
•The display remains illuminated for about 1.5 seconds.
•Pressing the Bbutton illuminates the display regardless of whether the auto light switch is on or off.
You may hear a faint rattling sound when you move the watch around. This sound is caused by the movement of a metal bulb that controls operation of the auto light switch, and does not indicate malfunction.
Illuminating the Display with the Auto Light Switch
The full auto light switch automatically illuminates the display whenever you angle the watch towards your face for reading, but only when it is dark.
•The full auto light switch does not illuminate the display
when surrounding light is bright.
The auto light switch is very handy for reading the display in the dark. The auto light switch illuminates the display for 1.5 seconds in all modes when you angle the watch towards your face.
❚To turn on the auto light switch
In any mode (except when a settings screen is on the display), hold down the D button for about two seconds to toggle the auto light switch on (auto light switch on indicator displayed) and off (no indicator displayed).

•Make sure that the left (9 o’clock) and right (3 o’clock) sides of the watch are within ±15 degrees of being parallel with the ground.
The auto light switch may not operate properly if the angle is greater.
Display Illumination Precautions•The light may be difficult to see if you turn it on under bright sunlight.
•If you press the Bbutton or if an alarm operation starts while the display is illuminated, illumination will turn off.
