Check Termination on the Clear-Com Partyline

How do you check termination on the Clear-Com partyline?

Measure the resistance between pins 1 and 3 on one channel XLR connector on the rear of the unit. Proper termination would measure approximately 4KΩ. A very high channel resistance means the channel is not terminated. Channel resistance of 2KΩ indicates a double-termination. If a double-termination is indicated, locate the other terminated power supply or main station and set its termination to "off".

Repeat this step for the other channels.
