FAQ
QWhat is the difference between the LR-4200 and the LR-5200?
AThe main difference is that the LR-5200 is programmable with a multi-function Listen button. It gives the user an opportunity to program only the desired channels and lockout the unused channels. This makes it simple to operate for end users that need to select between multiple active channels. The Listen Button can also be used to search for an active channel and lock the receiver on a specific channel.
QWhat is the purpose of Squelch?
AThe 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 can be programmed to the desired setting.
QWhat is the function of SQ?
ATo 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.
QWhat type of battery technology does the LR-4200 use?
AThe LR-4200 uses a non-proprietary field replaceable Lithium Ion battery.
QHow long does it take to fully charge the LR-4200?
AIt varies dependent on the depletion of the battery. A fully depleted battery will charge in 2.5 hours or less.
QHow many LR-4200 receivers can I use in a system?
AAs many as you need, the number is endless.
