FUNCTIONAL DESCRIPTION
13 LIQUID
CRYSTAL
DISPLAY A 5½ digit Liquid Crystal Display (LCD) displays the FREQUENCY/
CHANNEL that the transceiver is currently operating on. In SCAN mode it
displays the current frequency scanned if RF signal is present.
14 LOUDSPEAKER An 8-ohm internal speaker reproduces the receiver audio output. The audio
line is disconnected from the internal loudspeaker when the transceiver is
operated in Tx mode or when the SPEAKER/PHONE connector is in use.
15 SPEAKER/
PHONE
CONNECTOR A 3-pole connector provides interconnection to either an external
loudspeaker or headphone. When in use, the internal speaker is
disconnected and the VOLUME control sets the audio level applied to the
external speaker or headphone.
