PREPARATION
CONNECTING TO POWER
You can power your Listener from either an internal battery or AC power.
Using Battery Power
To power the Listener from an internal battery, you need one 9-volt battery (not
supplied). For the best performance and longest life, we recommend Ra-
dioShack alkaline batteries.
Caution:
Always use a fresh battery of the required size and recommended
type.
