Use extreme caution when you
install or remove a base station
CB antenna. If the antenna starts
to fall, let it go! It could contact
overhead power lines. If the
antenna touches a power line,
contact with the antenna, mast,
cable, or guy wires can cause
electrocution and death. Call the
power company to remove the
antenna. Do not attempt to do so
yourself!

Installation and Operation
instructions are for satisfying
FCC RF Exposure compliance.
To receive very weak signals,
turn SQUELCH
counterclockwise. You hear
noise between transmissions,
but you also hear weak
transmissions (those not strong
enough to break through a
higher squelch setting).
If you experience interference
from nearby frequencies, turn
RF GAIN counterclockwise to
reduce the receiver’s sensitivity.
