The DC breaker, on the rear panel, must be on (up) for transmitter operation, even

when using AC power. Electrically, the DC breaker is located immediately after

diodes which isolate the DC and AC power supplies.

All functions except switching AC power and the carrier are controlled through the

Control Knob and Main Display. To make a selection, turn the knob to scroll

through a list of choices. When the cursor arrow points to the selected function,

push and release the control knob to make the selection.

To enter a number or letter, use the control knob to move a flashing cursor block

over characters in the selected line. When the cursor is in position, push and release

the control knob. Then, turn the knob to scroll through the letter or number

choices. Push and release the knob to select the choice.
