Battery Life The values noted below indicate the number of hours before battery failure under normal

operating temperature (25°C). These values are for reference only, and do not guarantee that any particular set of batteries actually will provide the service life indicated. Low temperatures shorten battery life.

Type of Operation

Continuous Playback

Continuous Recording

•The above guidelines are based on the following battery types:

•Battery life varies with brand Continuous recording values show the number of shots without using the flash. The number of

shots depends on use of the flash and whether flash is turned on or off.

Power Consumption Approximately 7.3W Dimensions 131(W) x 69(H) x 43(D) mm Weight Approximately 250g (excluding batteries) Standard Accessories 8MB COMPACTFLASH memory card; strap; soft case; lens cap; video cable; data transfer

cable; PC Link CD-ROM; four LR6 alkaline batteries; Owner’s manual

*The camera also has a lithium battery that powers its built-in clock. When the power of this battery becomes weak, take the

camera to your CASIO Service Provider to have it replaced.

*The liquid crystal panel built into this camera is the product of precision engineering, with an effective pixel rate of 99.99%. This

also means, however that 0.01% of the pixels can be expected to fail to light or to remain lit at all times.

*U.S.A model can see a VIDEO OUT picture at the time of REC MODE.

( Other models cannot be carried out.)
