CAUTION: When installing antennas, ensure the antenna is clear of power lines. NOTES: If the RF signal to the 216 MHz model is too high, the audio will be distorted. This may happen if the LR-100 is within 40 feet of the LT-800-216 transmitter. Consider reducing the output power of the transmitter or optionally removing the antenna on the LR-100 (there is sufficient internal antenna inside the LR-100 to receive an adequate signal from the transmitter). -

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. -
Page 20: Coaxial Cable
Coaxial Cable The antenna for the LR-100 can be mounted directly on the unit if desired. However, you may find that the unit will provide better performance when the antenna is located elsewhere. If you plan to mount the antenna in a different location than on the top of the unit, you must use cable and connectors rated at 50 ohms. -
