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.

•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.
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 in the top dial, and the following operations become disabled as battery power recovers.

• | Time calibration signal reception | Indicator |
Normal operation will return after the battery recovers.

4 | timekeeping, disabled. |
•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 to 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 battery level indicator shows Level 3.
Point the solar panel (face) of the watch at a light source.
•Remember that even a partial blockage of the solar cell reduces charging efficiency.

• You can use the procedure under “Specifying the Illumination Duration” to configure the illumination duration as approximately 1.5 seconds or 2.5 seconds.
• Pressing the L button illuminates the display regardless of whether the auto light switch is on or off.
Illuminating the Display with the Auto Light Switch
The auto light switch automatically illuminates the display whenever you angle the watch towards your face for reading, but only when it is dark.
You can use the procedure under “Specifying the Illumination Duration” to configure the illumination duration as approximately 1.5 seconds or 2.5 seconds.
