118 Troubleshooting
Removing the microphone
For information on installing or removing your radio
from a vehicle, refer to the
TM9456 Installation and
Programming Guide
.
Notice
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.
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.
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.
General care
Your radio requires no regular maintenance other
than ensuring that all the cables and connections are
secure, and that no damage has occurred to the
antenna or wiring.
To prevent permanent damage to the radio cover, do
not allow the radio to come into contact with
detergents, alcohol, aerosol sprays or petroleum-
based products.
