● Insert NiMH batteries in the correct orientation.
● Use the camera, dock, or quick recharger in a dry location only.
● Do not charge NiMH batteries in a hot location, such as in direct sunlight or near a fire.
● When recharging NiMH batteries, do not cover the camera, dock, or quick recharger.
● Do not operate the camera, dock, or quick recharger if NiMH batteries appear damaged.
● Do not disassemble the camera, dock, or quick recharger.
