The support kit for concealed and dynamic microphones can be
used in two main applications:
to monitor activity around the radio if the radio is placed in
I
emergency mode, and
to support the use of a dynamic microphone, such as that used in
I
the TMAA10-02 handset.
The concealed and dynamic microphone support board plugs onto
the radio's control head PCB and contains circuitry for a pre-
amplifier and a microphone switch circuit. The concealed electret
microphone is installed inside the speaker grille of the control head.
