antenna to the transceiver via feed lines having an
impedance other than 50
Ω
reduces the efficiency of the
antenna system and can cause interference to nearby
broadcast television receivers, radio receivers, and other
electronic equipment.
ACCESSORY CONNECTIONS
EXTERNAL SPEAKER
If you plan to use an external speaker, choose a speaker
with an impedance of 8
Ω
. The external speaker jack
accepts a 3.5 mm (1/8") mono (2-conductor) plug.
MICROPHONE
For voice communications, connect a 600
Ω
microphone
equipped with an 8-pin modular plug into the modular
