COMM MEMORY 1, 2 & 3 PUSHBUTTONS - When a COM MEMORY pushbutton
is pressed, the preset selected frequency will appear in the COM frequency
window for use as the selected operating frequency. Each pushbutton will
illuminate white when pressed and the light will go out on the previously selected
pushbutton. Three preset frequencies may be stored in MEMORY and selected as
desired, by merely pressing the appropriate COM MEMORY pushbutton to recall
the desired operating frequency. If electrical power to the set's "keep-alive"
circuit has not been interrupted, upon turn-on, the set will automatically recall
the last COM MEMORY frequency selected by the MEMORY pushbutton. If
electrical power is removed from the set's "keep-alive" circuit (such as radio
removal or battery replacement) for more than 15seconds, upon turn-on, the COM
MEMORY circuits will have to be reset and COM 1 MEMORY will automatically
be selected with the lowest operating frequency (118.000 MHz) selected.
