Appendix A:
Managing Batteries
Your camera uses two AA batteries. Do not use ordinary
alkaline batteries. For best results, use Energizer Lithium AA or
rechargeable Nickel Metal Hydride (NiMH) AA batteries.
Top Points About Batteries
z
The first time that you use a set of NiMH batteries, be sure
that you fully charge them before using them in the camera.
z
If you do not intend to use your camera for extended
periods of time (more than two months), HP recommends
that you remove the batteries unless you are using
rechargeable batteries and are leaving the camera docked
or connected to an optional HP AC power adapter.
z
When inserting the batteries in the camera, always be sure
to orient the batteries as directed by the markings in the
battery compartment. If the batteries are inserted
improperly, the compartment door may close but the
camera will not operate.
z
Never use batteries of different chemistries (Lithium and
NiMH), brands, or ages. This can cause erratic camera
behavior, as well as battery leakage. Always use two
identical batteries of the same chemistry, brand, and age.
