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.
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.
External speaker adopt double port BTL, please care about the connecting 
way. The speaker can not connect with the ground, otherwise the speaker 
will be fault. The wrong connecting way as the following picture.
