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.
