PAGE 20 INSTRUCTION MANUAL TX4400
FITTING THE MICROPHONE
The microphone uses a miniature 6 pin telephone style plug
and socket.
To fit the microphone:
1. Position the microphone plug so the plastic tab faces
downwards. Press the plug into the socket until
it ‘clicks’.
2. Gently press the rubber strain relief into the hole
surrounding the socket so that the slot around the strain
relief fits neatly inside the lip of the hole.
Removing the microphone.
1. Squeeze the rubber strain relief near the front panel to
disengage the slot, and slide the strain relief back along
the microphone cord.
2. Press the small 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 pressed
again. You may need a small bladed screwdriver for this
task, as the tab can be difficult to reach with
your fingers.
