INSTALLATION
Your tX4500s is supplied with a DIn mounting
bracket for mounting into a standard DIn sized
cavity in the vehicle’s console or dashboard. Before
installing the radio, ensure the Dc cable and
antenna have been installed correctly (as described
on following pages) and the connectors are
accessible through the DIn cavity.
Installing the DIN Bracket
1. remove the four small front mounting screws
from the front edges of the DIn mount and
separate the front frame from the DIn surround.
2. slide the DIn surround into the DIn slot in the
vehicle’s console and secure it in the desired
position by bending the folding tabs.
3. slide the radio into the front frame from the front
until the threaded holes in the radio chassis line
up with the holes in the DIn frame.
4. secure the radio using the four 8mm bolts
supplied.
NOTE:
Bolts should not extend more than 6mm
inside the radio otherwise they may come into
contact with the internal components.
5. Feed the antenna connector and Dc lead through
the DIn slot in the dashboard and connect these
to the matching sockets on the radio.
6. slide the radio and front frame assembly into the
DIn surround and secure it using the four small
front mounting screws.
NOTE:
Bolts should not
extend more than 6 mm inside
the radio otherwise they may
foul the internal components.
