Removing the microphone
Notice For information on installing or removing your
radio from a vehicle, refer to the TM9300/TM9400
Installation Guide.
1 Using your thumb or forefinger, lift up one of the
corners of the microphone grommet and firmly (but
gently) pull that corner until the seal comes away
from the cavity.
Caution Remove the grommet carefully as it serves two
important functions. Firstly, it prevents damage to the
microphone socket due to movement of the
microphone cord, and secondly, it ensures that the
control head is sealed against water, dust, and other
environmental hazards.
2 Repeat to expose another corner.
3 Pull the exposed corners back and slide the grommet
up the cable to reveal the microphone plug.
4 Remove the plug from the microphone socket.
