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.
Keep the watch exposed to bright light
The electricity generated by the solar cell of the watch is
stored by a built-in battery. Leaving or using the watch
where it is not exposed to light causes the battery 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 the face so it is pointed at a source of bright
light.
• You should try to keep the watch outside of your sleeve
as much as possible. Charging is reduced significantly if
the face is even only partially covered.

• The watch continues to operate, even when it is not exposed to light. Leaving the
watch in the dark can cause the battery to run down, which will result in some watch
functions to be disabled. If the battery goes dead, you will have to re-configure watch
settings after recharging. To ensure normal watch operation, be sure to keep it
exposed to light as much as possible.

Read This Before You Set the Time and Date!
This watch is preset with a number of city codes, each of which represents the time
zone where that city is located. When setting the time, it is important that you first
select the correct city code for your Home City (the city where you normally use the
watch). If your location is not included in the preset city codes, select the preset city
code that is in the same time zone as your location.
• Note that all of the times for the World Time City codes and Dual Time City are
displayed in accordance with the time and date settings you configure for the
Timekeeping Mode.
To set the time and date
1. In the Timekeeping Mode, hold down A for about five
seconds until the left dial hand points to T1 and the city
code flashes on the upper display. This is the setting
mode.
2. Use D and B to select the city code you want.

changing any other setting.
