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.
Enter the PROGRAM mode
Press the UP and DOWN buttons simultaneously for 5 seconds, until the PGM symbol
appears in the display.
Use 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.
Press 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 program-
ming the unit and it automatically exits, press and hold the UP & DOWN buttons simultane-
ously for 5 seconds to re-enter the PROGRAM mode.
