telescopic
sections
fully

before
operating radio set. Failure to do this can
damage the radio operating capabilities.

stored position, and fully ex: tending telescopic sections; setting function
switch to either VOICE 282.8 or VOICE/MCW 243.0 position; and setting
VOL control towards MAX position. Proper receiver operation will be
indicated by a slight hissing sound in the MAX position. Presence of
squealing, "motorboating", or other abnormal sound (other than normal
AM static interference) is an indication of malfunction. Turn function
switch to OFF position.

cracked case, perforated seals, or presence of salt, sand, or oil
accumulations.
