Test Tone
Use the test tone to transmit a 400 Hz tone. This tone will allow the end user to know if the system is transmitting
properly. All receivers should be able to hear this tone if tuned to the proper channel.
Selecting Transmitting Frequencies
Use this section of the guide to choose the channel settings for the transmitter and receivers.
Find transmission channel(s)
The goal is to find a transmission channel(s) that is free from interference. Interference comes from
transmitters and other outside FM signals.
Listen’s LT-803-072 offers 3 different channels to choose from
With 3 different channels to choose from, the chance of finding an interference free channel is increased.
The best way to check for interference is to turn the LR-200-072 on and listen to each channel. Transmit on the
channel that has the least amount of noise.
