GmE model label. simply remove the backing tape and press

downwards, and press the plug into the socket until
it ‘clicks’.
2. Gently slide the rubber boat towards the hole surrounding
the socket until it is flush with the front panel.
Removing the microphone
1. slide the rubber boat back along the microphone cord.
2. squeeze the plastic tab on the microphone plug towards
the plug to unlock it while gently pulling the plug
outwards. if the plug does not come out easily, the tab has
not released correctly and should be squeezed again.

installations only (i.e. where the negative terminal of the
battery is connected to the chassis or frame of the vehicle).

chassis, or if preferred, directly to the battery’s
negative terminal.

positive lead could be connected into the fuse box at a point
that has +13.8 volts continuously available (the battery side of
