22 TMAA02-07 Concealed Microphone
The TMAA02-07 concealed microphone is installed inside the
speaker grille of the graphical-display control head. If the radio
is placed in emergency mode, the concealed microphone can be
used to monitor activity around the radio.
The TMAA02-07 kit is used for radios with a graphical display
control head. For radios with 1-, 2- or 3-digit display control
heads, the TMAA02-06 kit is used (refer to
“TMAA02-06
Support Kit for Concealed and Dynamic Microphones” on
page 519
).
