3. Installation
TCB-900 transceiver is designed to have a good performance in any
conditions that the transceiver operates, using rugged build chassis,
PCB’s and components. This transceiver is also designed for users’
convenience, implementing human ergonomics to locate the knobs
and buttons in the proper places. The combination of well designed
knobs and buttons as well as user friendly graphic layouts will lead
users to quickly adapt themselves for the easy operation. The newly
applied menu mode will make professional users more satisfactory
with pleasure. The elegant luxury and color changeable LED light
supporting the face design will go well with any vehicles.
This instruction manual has been designed to enable you to get the
best use from your CB Transceiver, therefore you are recommended
to take a few minutes to read this instruction manual before initial use
of your CB Transceiver.
Plan the location of the transceiver and microphone first, which is
most convenient for the operation. The transceiver should normally
be mounted horizontally, but may be mounted vertically. The bracket
supplied can be fitted above or below the case allowing the TCB-900
to be cradled by the bracket or suspended from it.
Your transceiver is supplied with a full range of accessories to help you
get started and virtually benefit from all the features straight away.

(4) Connect the power cable to
the transceiver cable.
Installation
Consider that this location of the transceiver should not interfere with the
driver and passengers. Choose a spot where the microphone and all
controls are easily accessible.
(1) Put the mounting bracket on the proper location where you are going
to install.
Drill holes and fix mounting bracket on the location.
(2) Connect the antenna cable plug to the standard receptacle on the
transceiver, which is marked “ANT”.
(5) Mount the microphone bracket on one side of the transceiver, or
near it using two screws included.
(3) Connect the power cable
directly to the vehicle battery or
fuse box of the car. Be careful to
make sure of the polarity of the
battery first and connect the
cable.(Red: Positive Pole(+),
Black: Negative Pole(-). The
same colours are shown on the
battery and in the fuse box of
the car.)
Connect the microphone to the
transceiver’s microphone recep-
tacle. Now you are ready to
operate the transceiver.

Installation
Installing an Antenna
It is very important to select a good quality high efficiency 27MHz
antenna. A poor quality antenna or one not designed for the 27MHz
band will give very poor performance and could cause damage to the
transceiver.
(1) Place the antenna as high as possible.
(2) The longer the antenna is, normally the better is the performance of
the transceiver.
Warning :Never try the operation of your transceiver before connecting
a proper antenna in order not to cause any damage.
(3) Try to mount the antenna in the centre of the surface that you
select.
(4) Make sure that you have a solid metal-to-metal ground connection.
(5) Be careful not to damage the cable during the installation.
