MANUAL TUNING PROCEDURE

Transmit sending a carrier of approximately 10 to 20 Watts to the coupler until the led goes off.

MEMORY USE
To enable memories we set the switch on the control box to the Y position. All frequencies we tune, up to 50,
are recorded. When we go to the same frequencies again and perform the tuning procedure ,the coupler is
almost instantly ready to be used. All it has to do is count the incoming signal frequency and use the tuning
