Owner’s Manual 77-120 ESP www.midlandradio.com Page 11 of 13 How ESP2™ works to make your CB sound better. The ESP2™ noise reduction system constantly monitors the signal strength and the type of noise present. When the signal strength is too low for good reception, the receiver sound is automatically adjusted to dramatically reduce the noise that comes through the speaker. While the noise is decreased the actual sounds you need to hear are increased. Skip interference can cause whistles and howling sounds. Electrical interference from power lines, ignition systems or other sources can produce low humming and buzzing noise. These high and low sounds are not needed for communications. ESP2™ can determine the difference between undesired noises and sounds you want to hear and filter the noises out. These results ESP2™ can accomplish without decreasing receiver range (it usually increases range). Most importantly, ESP2™ works by itself and does not need to be listening to other ESP2™ equipped CB’s to be 100% effective. The end result of ESP™ is that you can lower or completely stop using your squelch control. You will hear weak signals that cause other CB’s to hear only noise. With this new patented sound control system you will find yourself using your CB more thereby increasing your safety and enjoyment.
