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 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 connection.
The speaker can not connect with the ground, otherwise the speaker will be
fault.
