Installation

PA Speaker Installation

Mount PA speaker in desired location.

Plug jack into the back of the Connector Box 
labeled PA.
*The PA speaker should have 4-8 ohms impedance
and be able to handle at least 4 watts.

Public Address:

An external PA speaker may be

connected to the PA speaker jack when used as a public
address system. The speaker should be directed away
from the microphone to prevent acoustic feed-back.
Physical separation or isolation of the microphone and
speaker must be employed when operating the PA at high 
output levels.

Ignition Noise Interference

The alternator and ignition system in your vehicle may
limit your ability to receive low signal levels. Other noise
interference can be the result of several different
installation variables. Consult your Cobra dealer or a 2-way
radio technician to help locate and correct the source of
severe noise interference.
