FAQs

+What is the function of SQ?

To reduce noise of the systems, Listen offers a noise reduction technology called ListenSQ™. 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.

+What is the difference between the LR-400 and the LR-500?

The LR-500 gives the user an opportunity to lockout unused channels and has the controls on the outside of the front door.

+Can the LR-500 be used with multiple transmitters?

Yes. We recommend the LR-500 for use with multiple transmitters. The LR-500 is programmable and can be set to just those channels you need.

+How many receivers can I have in a system?

As many as you need, the number is endless.

+How many channels can I program into the LR-500?

One to 57. The receiver has 57 channels and you can program it to have just the channels you want to access. It can be a two channel receiver, a 12 channel receiver, or keep all channels.

+How long do the batteries last on the LR-500 receiver?

Alkaline batteries last 30 hours. NiMH rechargeable batteries last 15 hours (72 MHz and 216 MHz). With 863 MHz, Alkaline batteries last 20 hours and NiMH rechargeable batteries last 10 hours.
