LT-82 Setup and Operating Instructions

5Connect LT-82 Power to Radiator(s)(if desired)

The radiator(s) can be powered by either the transmitter Power Output or remotely with a power supply (LA-205) near the radiator. If powering the radiator(s) with the transmitter, connect the transmitter Power Output to the radiator Power Input with CAT-5 cable.

NOTE: A maximum of two radiators can be powered by each LT-82. It is important not to exceed powering more than two radiators per transmitter or external power supply.
