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

Bright Light

Solar panel

The electricity generated by the solar panel of the watch is stored by a rechargeable 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 signiﬁ cantly if the face is covered only partially.

E-1

• 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-conﬁ gure watch settings after recharging. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

shown at the top of the display, and the lap time and split time are shown in the middle and at the bottom. You can change the positions of the lap time and split time by pressing A while a stopwatch operation is in progress or stopped. For details, refer to “To position the lap time and split time on the display” (page E-20).

Dual timers can be set with two different starting times. The watch can be conﬁ gured so the two timers alternate, so when one reaches the end of its countdown, the other timer starts. You can specify a “number of repeats” value, which controls how many times the two-timer countdown operation is performed (1 = once, 2 = twice, etc.). The starting time of each timer can be set in ﬁ ve-second steps up to 99 minutes, 55 seconds. You can specify up to 10 repeats. The watch emits a short beep whenever either of the timers reaches the end of its countdown during an ongoing timer operation. The watch
