Congratulations upon your selection of this CASIO watch.
Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss suffered by you or any third party arising through the use of this product or its malfunction.
Important!
••Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down.
••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 power to run down. Make sure that the watch is exposed to bright light whenever possible.

Power Levels
You can get an idea of the watch’s power level by observing the movement of the x Second Hand in the regular timekeeping.

••When power drops to Level 3, all functions will be disabled but the watch will continue to keep time internally for about one week. If you recharge the battery sufficiently during this period, the analog hands will move automatically to the correct setting and regular timekeeping will resume. After one week, all settings (including timekeeping) will be cleared. Recharging the battery will reset all settings to their initial factory defaults.
Things to check before using the watch
1. During regular timekeeping, observe the movement of the x Second Hand.
••It can take as long as 14 minutes for the watch to resume normal operation when recovering from the sleep state. See “Power Saving”.

2. Check the current location setting.
Use the procedure under “Specifying Your Current Location and Setting the Time” to configure your location setting.
Important!
Proper time calibration signal reception and time settings depend on correct location setting. Make sure you configure these settings correctly.
3. Set the current time.
••To set the time using a time calibration signal See “To get ready for a receive operation”.
••To set the time manually
See “Specifying Your Current Location and Setting the Time”.
The watch is now ready for use.
••For details about the watch’s radio controlled timekeeping feature, see “Radio Controlled Atomic Timekeeping”.
Charging the Watch
The face of the watch is a solar cell that generates power from light. The generated power charges a

Power Saving
Power Saving enters a sleep state automatically whenever the watch is left for one week in an area where it is dark.
What happens when the watch is in the sleep state
••All hands move to 12 o’clock and stop.
••Auto Receive becomes disabled.

••It can take as long as 14 minutes for the watch to resume normal operation when recovering from the sleep state. Do not perform any watch operation during that time.
Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly. However, when using the watch outside of areas covered by time calibration signals, you will have to adjust the settings manually as required. See “Specifying Your Current Location and Setting the Time” for more information.
This section explains how the watch updates its time settings when the city name selected as the current location is in Japan or China, and is one that supports time calibration signal reception.
Charging Guide
Whenever you are not wearing the watch, leave it in a location where it is exposed to light.
••Best charging performance is achieved by exposing the watch to light that is as strong as possible.
Warning!
When wearing the watch, make sure that its face is not blocked from light by the sleeve of your clothing.
••The watch may enter a sleep state if its face is blocked by your sleeve even only partially.
