If you plan to use an external speaker, choose a speaker with an
impedance of 8Ω. The external speaker jack accepts a 3.5mm (1/8")
mono (2-conductor) plug.
For voice communications, connect a microphone equipped with an
8-pin modular plug into the modular socket on the front of the main
unit. Press rmly on the plug until the locking tab clicks. Attach the
supplied microphone hanger in an appropriate location using the
screws included in the screw set.
