14 TMAA10-01 Desktop Microphone
The TMAA10-01 desktop microphone is an omnidirectional 
dynamic microphone which can be used in dispatch 
situations, where the microphone is positioned on a flat 
surface. The desktop microphone plugs into the microphone 
socket on the radio control head.
The desktop microphone has an internal pre-amplifier and an 
adjustable sensitivity control on the underside of the desktop 
microphone base.
14.1 Operation
Hold down the monitor key and check whether the channel is clear.
If the channel is clear, press the PTT key to transmit. Speak clearly into the 
microphone and release the PTT key when you have finished talking.
Note The monitor key can be locked in the ‘on’ position. To do this, 
hold the monitor key down and slide the monitor key towards 
you. The monitor key should now be locked on.
14.2 Installation
Important The desktop microphone grommet must be installed 
whenever the desktop microphone is plugged into the 
microphone socket. When installed, the grommet has two 
functions:
■ to prevent damage to the microphone socket when 
there is movement of the microphone cord, and
■ to ensure that the control head is sealed against water, 
dust and other environmental hazards.
1. Plug the microphone cord into the microphone socket on the radio 
control head.
2. Slide the grommet along the cord and push two adjacent corners of the 
grommet into the microphone socket cavity.
