[. . . ] The unit incorporates microprocessor controlled PLL circuitry for precise tuning and increased function. Receiver noise and interference can now be largely eliminated by the new ESP2TM noise reduction system. Also included is a backlighted Liquid Crystal Display (LCD) digital information center that out-dates CB's with LED readouts. How to install your Midland mobile CB?This transceiver may be installed in any 12 volt negative ground-system car or truck. [. . . ] Warning: Never operate your CB radio without attaching an antenna or with a broken antenna cable.

However, performance can usually be improved by slightly lengthening or shortening its length, using a Standing Wave Radio (SWR) meter. For the exact procedures to be used refer to the antenna manufacturer's installation manual. You can buy an SWR meter separately or have your antenna checked by your Midland CB Dealer's service department or a two-way comm shop. www. midlandradio. com Page 7 of 13 Owner's Manual 77-120 ESP FUNCTION AND LOCATION OF CONTROLS FRONT PANEL CONTROLS 1.

This control can also be used to control optional power microphone output. SQUELCH CONTROL: Adjust this control until background noise just disappears. If the control is adjusted too far clockwise it may cause muting of weaker signals. RF GAIN CONTROL: This control adjusts the receiver, sensitivity.
