FAQ
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.
QHow many LR-5200 receivers can I use in a system?
AAs many as you need, the number is endless.
QHow long does it take to fully charge the LR-5200?
AIt varies dependent on the depletion of the battery. A fully depleted battery will charge in 2.5 hours or less.
QWhat type of battery technology does the LR-5200 use?
AThe LR-5200 uses a non-proprietary Lithium Ion battery.
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.
QHow long will the LR-5200 run on a fully charged battery?
AThe LR-5200 will run continuously for 8 hours on a fully charged battery.
QWhat is the warranty on the Lithium-ion battery?
AThe Lithium-ion battery has a 1 year warranty. All other accessories have a 90-day warranty. Listen Warranty
QWhat is the difference between the LR-5200 and the LR-4200?
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 are the ADA changes related to assistive listening systems?
ASimply put, any public assembly area where audible communication is integral to the use of the space, an assistive listening system shall be provided. The assistive listening receivers need to comply with the following table below. For full details visit: http://www.ada.gov/2010ADAstandards_index.htm
QCan the LR-5200 be used with multiple transmitters?

My overall impression is very positive. The sound is clear and connects well with my telecoils. It is lightweight and comfortable on my neck. I like that I can open the loop to put it on and off my neck so I don't attract attention and I don't mess up my hair (vanity is so important! LOL).
