Inserting Batteries and Attaching the Optional AC Adapter The following five types of batteries can be used with this camera, or you can use the optional AC adapter to connect the camera to a household power outlet. Battery Type Lithium battery pack CR-V3 (provided with camera) AA (R6) Ni-MH batteries (sold separately) AA (R6) Ni-Cd batteries Lithium polymer batteries (sold separately) (battery holder required) AA (R6) Alkaline batteries Battery Set 2 4 4 1 4 Rechargeable NO YES YES YES NO Caution To avoid damaging the camera from overheated batteries, never use AA (R6) zinc-carbon (manganese) or AA (R6) lithium batteries with this camera. Always use the identical batteries as a set, and never mix battery types. • The lithium battery pack CR-V3 cannot be recharged. • Performance of AA (R6) alkaline batteries varies considerably according to brand, battery age, and temperature. (Performance is particularly erratic at low temperatures.) In some cases these batteries may run down very quickly. We therefore recommend the use of Ni-MH batteries, lithium battery packs, or the lithium polymer battery in preference to AA (R6) alkaline batteries. Battery service life The service life of batteries is affected by many factors: battery type, manufacturer, how and where the camera is used, and so on. Note The following conditions listed below could cause the batteries to discharge quickly, even without taking pictures: • Repeatedly half-pressing the shutter button or turning the manual focus ring • Repeatedly zooming on a subject • Leaving the monitor on • Leaving the camera connected to a computer 16
