Connect an Earphone or Headset

Your headset or earphone will connect to the jack on the top of the unit. Either mono or stereo
connectors may be used with a Listen receiver. Make certain you push the plug all the way
into the jack.

Turn the Unit On

Receivers are turned on by rotating the volume dial counterclockwise. The red LED on top of
the unit should activate and the LCD display should illuminate. If they do not, make sure you
have installed the batteries correctly and that you are using fully charged batteries.
