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 firmly 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.
