Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to read this manual carefully.

Expose the watch to bright light to charge its capacitor before using it.

You can use this watch even as its capacitor is being charged by exposure to bright light.

x Be sure to read “Power Supply” on page E-17 of this manual for important information you need to know when exposing the watch to bright light.

E-1

Keep the watch exposed to bright light

Bright Light

Solar cell

E-2

The electricity generated by the solar cell of the watch is stored by a built-in capacitor. Leaving or using the watch where it is not exposed to light causes the capacitor to run down. Make sure the watch is exposed to light as much as possible.

When you are not wearing the watch on your wrist, position x the face so it is pointed at a source of bright light. You should try to keep the watch outside of your sleeve as x much as possible. Charging is reduced signiﬁ cantly if the face is only partially covered.

To set the time and date

In the Timekeeping Mode, press C to switch between the 12-hour and 24-hour formats.

When the 12-hour format is selected, the indicator x PM appears on the display to indicate “p.m.” times. There is no indicator for “a.m.” times.

While the seconds setting is selected (ﬂ ashing), press 3. C to reset it to 00. If you press C while the seconds setting is in the range of 30 to 59, the seconds are reset to 00 and 1 is added to the minutes. If the seconds setting is in the range of 00 to 29, the minutes count is unchanged. While any other setting is selected (ﬂ ashing), press 4. C to increase the number.

Holding down x C changes the setting at high speed.

After you set the time and date, press 5. B to return to the Timekeeping Mode.

Important!

Storing the watch for long periods in an area where there is no light or wearing it in x 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. This watch uses a special capacitor to store power produced by the solar cell, so x 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. Never try to remove or replace the watch’s capacitor yourself. Use of the wrong type x 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.

In the Countdown Timer Mode, press 1. A until the hours of the countdown start time start to ﬂ ash. This is the setting screen. After the hour setting is the way you want, press 2. A to move the ﬂ ashing to the minutes. While a setting is ﬂ ashing, use 3. C (+) to change it.

To set the starting value of the countdown time to x 24 hours, set

Press 4. A to exit the setting screen.

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.

Example: Orient the watch so its face

is pointing at a light source. The illustration shows how to position x a watch with a resin band. Note that charging efﬁ ciency drops x when any part of the solar cell is blocked by clothing, etc. You should try to keep the watch x outside of your sleeve as much as possible. Charging is reduced signiﬁ cantly if the face is only partially covered.

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.

On the dashboard of a car parked in direct sunlight x Too close to an incandescent lamp x Under direct sunlight x

Charging light

The watch will start to work within about three seconds after it is exposed to light x (such as indoor ﬂ uorescent lighting). Set the time and calendar at this time.
