Canon PowerShot A70 PowerShot A70/A60 Camera User Guide - Page 25

Preparing the Camera, Basic Functions When the camera's indicator blinks green, do not turn off the power or open the battery cover. The camera is writing, reading, erasing or transmitting an image to or from the CF card. • We recommend that you use the optional AC Adapter Kit ACK600 to power the camera during long usage sessions (p. 195). • The optional battery charger kit lets you use rechargeable NiMH batteries to power the camera (p. 193). • For important information, see Battery Performance (p. 214). • For information about the Battery and Charger Kit and AA-size rechargeable NiMH batteries, see the System Map (separate from this guide). Proper Battery Handling • Use AA-size alkaline or Canon AA-size NiMH batteries only. For information on handling the AA-size rechargeable NiMH batteries, see Using the Optional Battery Kits (p. 193). • Never use manganese or lithium batteries, as these battery types may overheat in the camera. • Since the performance of alkaline batteries may differ according to brand, the operating time of the batteries you purchase may not be as long as the batteries that came with the camera. • Camera operating time may shorten at low temperatures when alkaline batteries are used. Also due to their specifications, alkaline batteries may expire faster than NiMH batteries. If you are using the camera in cold areas or for a long time, we recommend using Canon AA-size NiMH Battery Kit (a fourpiece set). • While it is possible to use AA-size nickel-cadmium batteries, performance is unreliable and their use is not recommended. • Never mix unused and partially used batteries. Always load four fresh (or fully recharged) batteries at the same time. 21
