|Q||What is the difference between the LR-400 and the LR-500?|
|A||The LR-500 gives the user an opportunity to lockout unused channels and has the controls on the outside of the front door.|
|Q||Can the LR-400 be used with multiple transmitters?|
|A||Yes. The LR-400 can be used with multiple transmitters, but unlike the LR-500, it cannot be programmed to lock out channels.|
|Q||What is squelching?|
|A||The purpose of squelch is to mute the audio output of your receiver when the signal from the transmitter is turned off or is too weak to be received. Without squelch you would hear radio noise in your earphone. The squelch function is preset and cannot be changed on the LR-300.|
|Q||How many receivers can I have in a system?|
|A||As many as you need, the number is endless.|
