LR-500 Operation

LR-500 Operation Instructions

Make Sure the Unit is On

Rotate the volume knob counterclockwise with an earphone or headset connected to the unit. Listen receivers use the cable of the earphone or headset as a receiving antenna.

Be careful when turning the unit on - if you turn the knob too far you might get too much vol- ume in your earphone!

Select a Channel

Select the channel to match the transmission channel by pressing the UP and DOWN buttons on the receiver.

At 72MHz:

72MHz receivers operate on 17 wide band channels and 40 narrow band channels. Channels represented by letters on the display (i.e. A) are wideband channels ; channels represented by numbers are narrowband channels.

At 216MHz:

216MHz receivers operate on 19 wide band channels and 38 narrow band channels. Channel numbers starting with a “2” are wide band; channels beginning with a “1” or “3” are narrow band channels.

Refer to the Frequency Compatibility Tables (pages 60-63) for specific frequencies and com- patibility with other manufacturers.

Test the audio

If a transmitter is broadcasting on that channel, you will be able to hear the audio. If the sig- nal is too weak, the audio will be muted (squelched).

NOTE: Listen recommends the use of wide band transmitters.
