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?
Q
How many receivers can I have in a system?
A
As many as you need, the number is endless
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 the function of SQ?
A
To reduce noise of our systems, Listen now offers a noise reduction technology called ListenSQ™
(on 72 MHz and 216 MHz only). Both the transmitter and receiver must have SQ on to achieve the desired
results. If you are planning to use this product with older Listen systems or equipment not manufactured by
Listen, you should disable SQ.
