LR-300 Setup
Place Batteries in Unit
Place two AA batteries in the compartment, making note of the battery polarity shown in the
battery compartment, and again verifying that the BATTERY SELECT switch is in the correct
position for the batteries you are using. (ALK should be selected for all battery types other
than NiMH).
NOTE: Listen uses 1800mAh (milli-Amp-hour) constant current NiMH (Nickel Metal
Hydride) batteries. These may be purchased from your Listen dealer (ask for part number
LA-362).
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.
