You can set five independent Daily Alarms. When an alarm is turned on, the alarm tone sounds when the alarm time is reached.
You can turn on an Hourly Time Signal that causes the watch to beep twice every hour on the hour.
ξThere are six screens in the Alarm Mode. Five are for
daily alarms (indicated by numbers from through | ), |
and one is for the Hourly Time Signal (indicated by | ). |

Mode indicator
The countdown timer can be set within a range of one minute to 24 hours. An alarm sounds when the countdown reaches zero.
ξThe countdown operation continues even if you exit the Countdown Timer Mode.
ξAll of the operations in this section are performed in the Countdown Timer Mode, which you enter by pressing B (page
To use the countdown timer
Press Cwhile in the Countdown Timer Mode to start the countdown timer.
ξWhen the end of the countdown is reached, the alarm sounds for 10 seconds or until you stop it by pressing any button. The countdown time is reset to its starting value automatically after the alarm stops.

ξTo stop a countdown operation completely, first pause it (by pressing C), and then press A. This returns the countdown time to its starting value.
Power Supply
This watch works by light energy, so no battery is necessary. Light energy is converted into electric energy by the solar cell and stored by the capacitor. The illustration shown below shows how you should position the watch for charging.
To set the countdown start time
1.In the Countdown Timer Mode, press Auntil the hours of the countdown start time start to flash. This is the
setting screen.
2. After the hour setting is the way you want, press Ato move the flashing to the minutes.
3. While a setting is flashing, use C(+) to change it. ξ To set the starting value of the countdown time to
24hours, set.
4.Press Ato exit the setting screen.
Example: Orient the watch so its face is pointing at a light source.
ξThe illustration shows how to position a watch with a resin band.
ξNote that charging efficiency drops when any part of the solar cell is blocked by clothing, etc.
ξYou should try to keep the watch outside of your sleeve as much as possible. Charging is reduced significantly if the face is only partially covered.
Solar cell
Charge indicator
Important!
ξStoring 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 capacitor power to run down. Make sure that the watch is exposed to bright light whenever possible.
ξThis watch uses a special capacitor to store power produced by the solar cell, so regular capacitor replacement is not required. However, after very long use, the capacitor may lose its ability to achieve a full charge. If you experience problems getting the capacitor to charge fully, contact your dealer or CASIO distributor about having it replaced.
ξNever try to remove or replace the watch’s capacitor yourself. Use of the wrong type of capacitor can damage the watch.
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 capacitor. 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 capacitor 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.
ξOn the dashboard of a car parked in direct sunlight
ξToo close to an incandescent lamp
ξUnder direct sunlight
Charging light
ξThe watch will start to work within about three seconds after it is exposed to light (such as indoor fluorescent lighting). Set the time and calendar at this time.
ξCharge indicator “” appears on the display when the capacitor charge level is low.
ξIf you continue to use the watch without exposing it to light after “” appear, the watch will stop functioning after about three days.
ξTake steps to charge the watch’s capacitor as soon as possible after “” appears. See “Recovery Times” (page
ξThe daily alarm, Hourly Time Signal, and other tones will not sound while “” is on the display. Also, display figures may become dim.
