Squelch Control - Kraco KCB-2340 User Manual

2. Connect Black power lead from the transceiver to any convenient hot (negative) side
of the electrical system or Minus (—) battery terminal.
NOTE: If you are not sure of the electrical ground system employed in your vehicle, please
consult with your car dealer. But when you cannot obtain the necessary information,
directly connect the Red power lead to the Plus (+) battery terminal and Black power
lead to the Minus (—) battery terminal to avoid damaging the transceiver.
ANTENNA CONNECTION
BEFORE OPERATING THE TRANSCEIVER, YOU MUST CONNECT A PROPER ANTENNA
SYSTEM. OPERATING THE TRANSCEIVER WITHOUT AN ANTENNA OR A DUMMY LOAD
MAY CAUSE DAMAGE TO THE EXPENSIVE RF POWER TRANSISTORS.
The antenna is one of the most important factors in the operation of the transceiver with its full
efficiency. An improper antenna may decrease reception sensitivity and lower the communication
range in transmitting. The CB antenna and its mounting method will largely depend upon your
type of vehicle, mounting position, etc. Also the antenna may be different according to your
needs — using the transceiver as a mobile, or base station transceiver. We recommend you consult
the dealer from which you purchased the transceiver or any other CB/Amateur radio equipment
supply shop. They will meet your specific needs.
DESCRIPTION ON FRONT & REAR PANEL FACILITIES
VOLUME/POWER SWITCH
This turns power on or off. To turn the power on, rotate the knob clockwise; and to turn off,
rotate all the way counter clockwise until a click is heard. Turning the knob clockwise increases
the volume from the built-in speaker. This volume does not affect the transmit power.
SQUELCH CONTROL
This silences undesirable background noise when no signal is received. The squelch level can be
varied by adjusting the control knob. Usually this will be done as follows:
1. Turn the power on and rotate the VOLUME knob until a background noise is heard.
2. Then rotate the SQUELCH control knob clockwise until the background noise disappears.
3. Now you can receive signals without annoying background noises. However, rotating the
squelch control too far clockwise direction decreases reception sensitivity and a very weak
station would not be received, therefore when you want to communicate with such a station,
rotate the squelch control all the way counter clockwise.
CLARIFIER
During AM operation, place the control in the "12" o'clock position. However, if a station received
is not clear, adjust the control for clearei reception.
