LR-500 Programming Instructions

The LR-500 Display Receiver has some special features not available in the other receivers: you may lock out unwanted channels, and you can adjust the squelch in the unit.

Locking Out Unwanted Channels

For applications where users are required to select a channel (such as language interpretation or classrooms), and you don’t want them to have to go through all 57 available channels to find the appropriate channel, you can lock out all channels except the ones you are using in your facility.

UP and DOWN buttons on front of LR-500

1Enter the PROGRAM mode

Press the UP and DOWN buttons simultaneously for 5 seconds, until the PGM symbol appears in the display.

2Use the UP and DOWN keys to select channels

As channels are displayed on the unit, those channels that are locked out from user access will be indicated by the L/O (Locked Out) symbol. When a channel is locked out, the receiver will skip over that channel when a user is tuning the receiver.

3Press the SEEK button to toggle channels between locked out and non-locked out modes

Exiting PROGRAM mode

To exit the PROGRAM mode, let the receiver sit idle (don’t press any buttons) for 5 seconds. The receiver will automatically return to normal operation. If you haven’t finished programming the unit and it automatically exits, press and hold the UP & DOWN buttons simultaneously for 5 seconds to re-enter the PROGRAM mode.
