1. Introduction
TCB-770 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 and luxury blue 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.
2. Supplied Accessories
Your transceiver is supplied with a full range of accessories to
help you get started and virtually benefit from all the features
straight away.

Microphone mounting bracket
3. Installation
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-770 to be cradled by the bracket or
suspended from it.

ENGLISH
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.
2) Drill holes and fix mounting bracket on the location.
3) Connect the antenna cable plug to the standard receptacle
on the transceiver, which
is marked "ANT".
4) 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.)
5) Connect the power cable to the transceiver cable.
6) Mount the microphone bracket on one side of the transceiver,
or near it using two screws included.
7) Connect the microphone to the transceiver’s microphone
receptacle. Now you are
ready to operate the
transceiver.

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.
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.
Warning : Never try the operation of your transceiver before
connecting a proper antenna in order not to cause any damage.

details of information.
ENGLISH
3) Emergency Button
Pressing this button will lead you to the emergency
channel, "CH 9" and the EMG icon will be displayed.
The channel selector and quick up/quick down
buttons will not work. To return to the previous operation mode, momentarily press the emergency button again.
6
4) Scan/Lock Button
Scan : Press this button momentarily to start
scanning upward to catch any channels that are
occupied by others.
To activate/deactivate the channel scan, press the Scan button
briefly. The Scan icon will appear when the channel scan is
active. Scanning will only stop when you deactivate the scan
function.
Turn the channel selector counter-clockwise during scanning in
order to change the scanning direction.
The transceiver will scan through the whole transceiver
channels. If your transceiver detects a valid signal the scan will
pause for the period that has been set by the menu mode setting
(continuously receiving or 1-99 seconds for scan receive time
and immediate response or 1-99 seconds for scan delay time).
If you press the PTT button when your transceiver detects a
signal, the radio will transmit on the same channel. Scanning
will resume after the scan receive time and/or the scan delay
time. Use the channel selector or quick up/quick down selector
to resume scanning immediately.
If you press the PTT button during scanning, the radio will
return to your original channel. Scanning will resume after the
scan receive time and/or the scan delay time. Use the channel
selector or quick up/quick down selector to resume scanning
immediately.
Lock : Press this button for more than 2 seconds to activate
and deactivate the keypad lock function. This function locks
only the channel selector, quick up/quick down buttons, scan
button. Other buttons and selectors work normal.
5) AM/FM and LCR Button
When the transceiver is used in UK, UE, or EC
freequency band modes this button activates or
deactivates Last Channel Recall function. In all
other modes (where national regulations permit
this), this button allows user to switch between AM and FM
modes by momentarily pressing this button.

8) Microphone Gain Knob
Turn this knob clockwise and counter-clock until
you get better microphone gain while you move the
microphone to the optimum distance from your
mouth.
9) RF Gain Knob
Turn this knob clockwise until you get better RF
gain. You may need to decrease the sensitivity by
turning the knob counter-clockwise when there is a
very strong signal.
10) Squelch Control knob
Turn this knob counter-clockwise until you hear the
background noise and then turn the knob a little
clockwise until the noise disappears. In this
way, you get the best receive sensitivity.
11) Volume and Power On/Off Knob
To switch on the transceiver turn this knob
clockwise. After clicking sound the transceiver is
switched on. The more you turn this knob
clockwise, the bigger the audio sound grows.
12) Channel Selector
Turn right or left, and this allows you to select the
channel one by one that you like to use.

10. Trouble Shooting
If you experience problems with your TCB-770 transceiver, first
check the power supply source. Poor connection of the power
supply source can cause problems such as no transmission,
no reception or poor reception, and weak or no sound. Ensure
that the microphone and antenna are also well connected.
If this does not solve the problem, reset your transceiver as
follows.
1) Switch off the transceiver.
2) Pressing EMG button, switch on the
transceiver.
This will reset the transceiver, so all the memories are erased
and the parameters return to the initial factory setting.
This should fix most problems. In case of further difficulty,
please consult your dealer or visit our website.
