Public address
An external 8 ohms, 3 Watt speaker must be connected to the PA jack
located on the rear panel when the transceiver is used as a public
address system. The speaker should be directed away from the
microphone to prevent acoustic feedback. Physical separation or
isolation of the microphone and speaker is important when operating
the PA at high output levels.
