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, and 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. 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.
Disconnecting the Microphone
It is recommended that the microphone be left permanently
connected to the TX3420, but if it must be disconnected,
proceed as follows:
1. Insert a small screwdriver between the rubber boot and
the lip of the raised area on the front panel.
2. Ease the rubber boot out of the cable entry hole and
slide it along the cable away from the front panel.
3. Identify the plug locking lever, work the screwdriver
blade behind it and move the lever towards the plug
body. At the same time gently pull the plug from the
socket (see diagram below).
If required, replacement microphones are available with
plug and rubber
boot already fitted.
