Removing the microphone
1. Slide the rubber boot 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.
DC POWER CONNECTION
The TX3345 is designed for 13.8 volts DC, negative earth
installations only (i.e. where the negative terminal of
the battery is connected to the chassis or frame of the
vehicle).
There are two recommended methods of installation.
Radio remains ON when the ignition switch is OFF
Connect the radio’s negative (black) lead to the vehicle’s
chassis, or if preferred, directly to the battery’s
negative terminal.
The radio’s positive (red) lead should be connected
via the 2 amp fuse to the battery’s positive terminal.
Alternatively, the positive lead could be connected into
the fuse box at a point that has +13.8 volts continuously
available (the battery side of the ignition switch) via the
2 amp fuse.
Radio turns OFF with the ignition switch:
Connect the radio's negative (black) lead to the vehicle's
chassis, or if preferred, directly to the battery's
negative terminal.
The radio's positive (red) lead should connect to an
accessory point in the vehicle's fuse box via the 2 amp
fuse. This point should 13.8 volts only when
the ignition switch is turned ON or in the ACCESSORY
position.
