OPERATION
(1) Check polarity and the required keying voltage and current on your transmitter key terminals,
using a tester (voltmeter, milliameter) the key up (open circuit) voltage must not be in excess of
.50 volts D.C.
(2) Connect the key line (output) [11] on the rear panel terminal (+) to the POSITIVE keying
terminal of the transmitter, and the (–) to the NEGATIVE terminal, as previously determined by
voltmeter test (1).
