INSTALLATION
NOTE:
the tX4800 is designed for connection to
negative earth electrical systems only .
SELECTING A LOCATION
it is advisable to spend a little time selecting the best
location for the tX4800 . the mounting bracket can be
rotated above, below or behind the radio enabling the
radio to be mounted in a wide range of locations . in
addition, using the optional flush mounting kits (mK600,
mK001, mK002) the tX4800 can be mounted directly in
a panel or dashboard .
Upright or Overhead Mounting
Keep the following points in mind when choosing
a location .
•
the tX4800 is designed to meet the iP67 specification
which allows for direct water spray . However, we
recommend you select a location that will minimise
excessive exposure to water splashes or
continuous rain .
•
select a location that won’t expose your radio
to continuous direct sunlight which could cause
overheating or uV degradation .
•
Ensure that the location allows a free flow of air
around the heat sink on the back of the radio .
•
the microphone and all controls should be readily
accessible and the loud speaker easily heard from the
normal driving position .
•
For best results connect the battery leads directly
to the vehicle's battery . if you need to extend the
power leads to reach the battery use heavy insulated
automotive wire of at least #10 gauge .
INSTALLING THE UNIT
After choosing your location, hold the unit with the
mounting bracket attached into the desired position and
mark the location with a pencil . remove the mounting
bracket from the radio and drill the mounting holes . Bolt
or screw the bracket in place using hardware suitable
for the mounting surface . the unit is supplied with
stainless steel screws; however, if the mounting surface is
unsuitable for screws you may need to replace these with
stainless steel bolts .
DC Connections
connect the rED power lead to the Positive (+) side of
the battery or to an accessory point in the fuse box .
connect the BlAcK power lead to the negative (-) side of
the battery or to a suitable ground point .
Note:
the power lead is supplied with two 10 Amp
fuses . if the fuse blows, use only a standard 10 Amp
BlADE fuse as a replacement . use of higher rated fuses
or 'slow blow’ types could result in damage to your radio
which would void the warranty .
connect the antenna cable to the rear antenna socket on
the radio using a Bnc coaxial connector .
in a high noise environment an extension speaker may be
installed close to the operator . the internal speaker may
be disconnected if required .
