150 Handling Precautions Camera Avoid Strong Magnetic Fields z Never place the camera in close proximity to electric motors or other equipment generating strong electromagnetic fields. Exposure to strong magnetic fields may cause malfunctions or corrupt image data. Avoid Condensation Related Problems z When moving the equipment rapidly from cold to hot temperatures, you can avoid condensation by placing the equipment in an airtight, resealable plastic bag and letting it adjust to temperature changes slowly before removing it from the bag. Moving the equipment rapidly from cold to hot temperatures may cause condensation (water droplets) to form on its external and internal surfaces. Battery z This camera uses AA-size alkaline batteries or Canon AA-size NiMH batteries (sold separately). While it is possible to use AA-size nickel-cadmium batteries, performance is unreliable and their use is not recommended. z 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. z When using the camera under low temperature conditions or over long periods, you are recommend to use Canon AA-size NiMH batteries (sold separately). 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. z Never mix unused and partially used batteries. The partially used batteries may leak.
