[. . . ] : As the transceiver has a frontal microphone socket, it can be set into the dash board. In this case, you will need to add an external loud speaker to improve the sound quality of communications (connector EXT. A) Choosing your antenna: - For CB radios, the longer the antenna, the better its results. B) Mobile antenna: - Must be fixed to the vehicle where there is a maximum of metallic surface (ground plane), away from windscreen mountings. [. . . ] - There are two types of antenna: pre-regulated which should be used on a good ground plane (e. Adjustable which offer a much larger range and can be used on a smaller ground plane (see p 27 § 5, Adjustment of SWR). - For an antenna which must be fixed by drilling, you will need a good contact between the antenna and the ground plane. To obtain this, you should lightly scratch the surface where the screw and tightening star are to be placed. - Be careful not to pinch or flatten the coaxial cable (as this runs the risk of break down and/or short circuiting). C) Fixed antenna: - A fixed antenna should be installed in a clear a space as possible. If it is fixed to a mast, it will perhaps be necessary to stay it, according to the laws in force (you should seek professional advice). All PRESIDENT antennas and accessories are designed to give maximum efficiency to each CB radio within the range. Your PRESIDENT TRUMAN ASC is protected against an inversion of polarities. However, before switching it on, you are advised to check all the connections. Your equipment must be supplied with a continued current of 12 volts (A). It gives better quality of communication (squelch adjustment needs more finesse). The bargraph shows the level of reception and the level of power emitted. These filters allow the reduction of back ground noise, and some reception interference. This plug is situated on the front panel, thereby making it easier to set the equipment into the dashboard. An external loud speaker can be connected to your PRESIDENT TRUMAN ASC by the jack plug situated on the back panel PA. By pressing the PA key, the message transmitted into the microphone will be directed towards the external speaker and be amplified. Hold the microphone far enough away from this loud speaker so as to avoid the Larsen effect. Depress this knob to transmit a message and release to listen to an incoming communication. The modulation mode must correspond with that of the person with whom you communicate. Check that the PA function is not activated Check that the squelch level is properly adjusted. - Check that you are using the same modulation mode as your correspondent. [. . . ] Now that you have read the manual, make sure that your CB Radio is ready for use (i. Choose your mode (AM/FM) which must be the same as that of your correspondent. Press the «push-to-talk» switch and announce your message «Attention stations, transmission testing» which will allow you to check the clearness and the power of your signal. If you use a calling channel (19, 27) and you have established communication with someone, it is common practice to choose another available channel so as not to block the calling channel. [. . . ]
