For proper and dependable operation, Listen receivers should receive a strong and
consistent signal from the originating transmitter. The following strategies should be used
maximize this signal:
When designing and installing your system, keep in mind that the location of both the
transmitting and receiving antennas is critical to maximizing signal strength.
Eliminate or minimize obstructions between the transmitting antenna and the receiving
antenna.
Minimize the distance between the transmitting and receiving antennas.
Move transmitting and receiving antennas away from metal objects.
Place the transmitting antenna as high as possible.
Orient both transmitting and receiving antennas vertically.
For 216 MHz unit only, consider using a gain antenna such as a Yagi type antenna.
CAUTION: When installing antennas, ensure the antenna is clear of power lines.
NOTE: If the RF signal to the 216 MHz models is too high, the audio will be distorted. This may
happen if you are within 40 feet of the LT-800-216 transmitter.
In an overload condition, the LR-100 will go into a protective state to protect the unit and
power supply from excessive current and heat. This condition will occur if the speaker
terminals are shorted to each other or if they are shorted to the chassis for over 15 seconds.
In this condition, the LR-100 will no longer function normally. If the LR-100 stops functioning
normally, do the following:
Turn the unit off and unplug it from power. If you are operating the LR-100 with an external
+12VDC source such as a battery, disconnect the power source from the unit.
Remove the short to the speaker terminals.
Wait 30 seconds or longer.
Plug the unit back in and turn the power on.
The LR-100 should now function normally. If the unit is still not functioning normally, contact
Listen Support.
