TCB-771 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.
Your transceiver is supplied with a full range of accessories to help
you get started and virtually benefit from all the features straight
away.
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-771 to be cradled by the bracket or suspended from it.
