INSTALLING BATTERIES
The MA002 Amplifier operates with two 9-volt alkaline batteries. Two battery compartments can be found
on the back of the amp, on either side of the speaker.
Replace both batteries by following these steps:
Open the battery compartment door, pinch the tab, and pull the door to open.
To install a new battery, snap the +/- terminals of the battery into place on the connector pad.
Place the attached battery into the compartment.
Close the compartment door.
Do not mix old and new batteries. Do not mix alkaline standard (carbon-zinc) and rechargeable (nickel-
cadmium) batteries.
