The camera and monitor can be powered by batteries or by the
included adapter. We recommend saving batteries by using the
power adapters whenever possible. The batteries are disengaged
automatically if adapters are connected.
•Do not mix old and new batteries.
•Do not mix alkaline, standard (carbon zinc), or rechargeable
(nickel cadmium) batteries.
Batteries may leak or explode if recharged, inserted improperly,
inserted in the wrong direction, disposed of in a fire or mixed
with different battery types.
Battery compartments are located on the rear of both units. Use
the edge of a coin to unscrew the camera battery door lock.
