6 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.
6.1 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.
6.2 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.
