To set an alarm time
You can set three independent Daily Alarms. When an alarm is turned on, the alarm tone sounds when the alarm time is reached. You can also turn on an Hourly Time Signal that causes the watch to beep twice every hour on the hour.
•The alarm and Hourly Time Signal operate in accordance with the current digital time.
•The alarm number (AL1 though AL3) indicates an alarm screen. SIG appears in place of the alarm number when the Hourly Time Signal screen is shown.
•All of the operations in this section are performed in the Alarm Mode, which you enter by pressing C.
1.In the Alarm Mode, press Dto select the alarm whose time you want to set.

2.Hold down Auntil the hour setting of the alarm time
starts to flash, which indicates the setting screen.
• This automatically turns on the alarm.
This watch is equipped with a solar cell and a rechargeable battery (secondary battery) that is charged by the electrical power produced by the solar cell. The illustration shown below shows how you should position the watch for charging.
Example: Orient the watch so its face
is pointing at a light source. | Solar cell |
• The illustration shows how to position |
|
a watch with a resin band. |
|
• Note that charging efficiency drops |
|
when any part of the solar cell is |
|
blocked by clothing, etc. |
|
•Normally, you should try to keep the watch outside of your sleeve as much as possible. Charging is significantly
reduced if the face is only partially covered.
Important!
• Storing the watch for long periods in an area where there is no light or wearing it in |
such a way that it is blocked from exposure to light can cause rechargeable battery |
power to run down. Make sure that the watch is normally exposed to bright light |
whenever possible. |
• Normally, the rechargeable battery should not need replacement, but after very long |
use over a number of years, the rechargeable battery may lose its ability to achieve |
a full charge. Should you notice problems with getting the rechargeable battery to a |
full charge, contact your dealer or CASIO distributor about having it replaced. |
• The rechargeable battery should be replaced with a |
battery only. Other rechargeable batteries can cause damage to the watch. |

Stopwatch
• All data stored in memory is deleted, and the current time and all other settings |
return to their initial factory defaults whenever battery level drops to Level 4 and |
when you have the battery replaced. |
• Turn on the watch’s Power Saving function and keep it in an area normally exposed |
to bright light when storing it for long periods. This helps to keep the rechargeable |
battery from going dead. |
To check the current battery level
In the Timekeeping Mode, press Conce to display the battery level indicator.
•The battery level indicator shows the battery level either as HI (Level 1) or MID (Level 2).
•If the battery level drops below Level 2 (MID), a charge soon alert (Level 3) is displayed in all modes.

Illumination
An LED
• See “Illumination Precautions” for other important information.
To illuminate the display
In any mode, press Bto illuminate the display.
• You can specify 1.5 seconds or 2.5 seconds as the illumination duration. See “To set the current digital time and date manually” for more information.
• The flashing charge indicator ( C ) at Level 3 tells you that battery power is very low, and that exposure to bright light for charging is required as soon as possible.
• At Level 4, all functions are disabled and settings return to their initial factory defaults. Functions are enabled once again after the rechargeable battery is charged, but you need to set the time and date, after the battery reaches Level 2 from Level 4.
• Leaving the watch in direct sunlight or some other very strong light source can cause the battery level indicator to temporarily show a reading that is higher than the actual battery level. The correct battery level indicator should appear after a few minutes.
• If you use the light or alarms a number of times during a short period, the recover indicator ( R ) appears on the display and the following operations become disabled until battery power recovers.

After some time, battery power will recover and the recover indicator will disappear, indicating that the above functions are enabled again.
Charging Precautions
Certain charging conditions can cause the watch to become very hot. Avoid leaving the watch in the areas described below whenever charging its rechargeable battery. Also note that allowing the watch to become very hot can cause its liquid crystal display to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature.
Warning!
Leaving the watch in bright light to charge its rechargeable battery can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.
•On the dashboard of a car parked in direct sunlight
•Too close to an incandescent lamp
•Under direct sunlight
