Speaker Attachment/Detachment:

Attaching Speakers: Position the speaker next to the main unit, ensuring the top of the speaker rises one inch above the main unit's top and the four hooks on the main unit sit flush inside the rectangular indent on the speaker.

A flat head screwdriver is needed to gently push the switch to the desired voltage (110V or 220V). After setting, the battery compartment lid should be replaced.

Battery Installation:

To install batteries, remove the lid from the battery compartment [23]. Load eight "D" size batteries, carefully matching the polarities indicated inside the compartment. This ensures the unit can be powered on the go.
