9、lcome to the world of the new generation of radios. The new PRESIDENT range gives you access to top performance radios equipment. With the use of up-to-date technology, which guarantees unprecedented quality, your PRESIDENT JFK II A+ ASC is a new step in personal communication and is the surest choi

10、ce for the most demanding of professional radio users. To ensure that you make the most of all its capacities, we advise you to read carefully this manual before installing and using your PRESIDENT JFK II A+ ASC. A) INSTALLATION 1) WHERE AND HOW TO MOUNT YOUR MOBILE RADIO a) You should choose the mo

11、st appropriate setting from a simple and practical point of view. b) Your radio should not interfere with the driver or the passengers. c) Remember to provide for the passing and protection of different wires (e.g. power, antenna, accessory cabling) so that they do not in any way interfere with the

12、driving of the vehicle. English 5 OUTPUT RADIUS PATTERNS 2) ANTENNA INSTALLATION a) Choosing your antenna - For radios, the longer the antenna, the better its results. Your dealer will be able to help you with your choice of antenna. b) Mobile antenna - Must be fi xed to the vehicle where there is a

13、 maximum of metallic surface (ground plane), away from windscreen mountings. - If you already have a radio-telephone antenna installed, the PRESI- DENT antenna should be higher than this. - There are two types of antenna: pre-regulated which should be used on a good ground plane (e.g. car roof or li

14、d of the boot), and adjustable which offer a much larger range and can be used on a smaller ground plane (see 5 page 7, Adjustment of SWR). - For an antenna which must be fi xed by drilling, you will need a good contact between the antenna and the ground plane. To obtain this, you should lightly scr

15、atch the surface where the screw and tightening star are to be placed. - Be careful not to pinch or fl atten the coaxial cable (as this runs the risk of break down and/or short-circuiting). - Connect the antenna (B). c) Fixed antenna: - A fi xed antenna should be installed in a clear a space as poss

16、ible. If it is fi xed 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 effi ciency to each radio within the range. 3) POWER CONNECTION Your PRESIDENT JFK II A+

17、 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). Today, most cars and lorries are negative earth. You can check this by making sure that the n

18、egative terminal of the battery is connected either to the engine block or to the chassis. If this is not the case, you should consult your dealer. WARNING: Trucks generally have two batteries and an electrical installation of 24 volts, in which case it will be necessary to insert a 24/12 volt conve

19、rter (type CV 24/12 PRESIDENT) into the electrical circuit. The following connection steps should be carried out with the power cable disconnected from the set. a) Check that the battery is of 12 volts. b) Locate the positive and negative terminals of the battery (+ is red and - is black). Should it

20、 be necessary to lengthen the power cable, you should use the same or a superior type of cable. English 6 c) It is necessary to connect your radio to a permanent (+) and (-). We advise you to connect the power cable directly to the battery (as the connection of the radio cable to the wiring of the c

21、ar-radio or other parts of the electrical circuit may, in some cases, increase the likelihood of interference). d) Connect the red wire (+) to the positive terminal of the battery and the black (-) wire to the negative terminal of the battery. e) Connect the power cable to your radio. WARNING: Never

22、 replace the original fuse (5 A) by one of a different value. 4) BASIC OPERATIONS TO BE CARRIED OUT BEFORE USING YOUR SET FOR THE FIRST TIME (without transmitting and without using the push-to-talk switch on the microphone) a) Connect the microphone b) Check the antenna connections c) Turn the set o

23、n by turning the VOL knob (1) clockwise. d) Turn the squelch SQ knob (2) to minimum (M position). e) Adjust the volume to a comfortable level. f) Go to 28.555 MHz frequency by using the channel selectors (5). 5) ADJUSTMENT OF SWR (Standing wave ratio) WARNING: This must be carried out when you use y

24、our radio for the fi rst time (and whenever you re-position your antenna). The adjust- ment must be carried out in an obstacle-free area. * Adjustment with external SWR-meter (e.g. TOS-1 PRESIDENT) a) To connect the SWR meter - Connect the SWR meter between the radio and the antenna as close as poss

25、ible to the radio (use a maximum of 40 cm cable, type President CA 2C). b) To adjust the SWR meter - Set the radio to 28.555 MHz frequency. - Put the switch on the SWR-meter to position FWD (calibration). - Press the push-to-talk switch on the microphone to transmit. - Bring the index needle to by u

26、sing the calibration key. - Change the switch to position REF (reading of the SWR level). The reading on the Meter should be as near as possible to 1. If this is not the case, re-adjust your antenna to obtain a reading as close as possible to 1. (An SWR reading between 1 and 1.8 is acceptable). - It

27、 will be necessary to re-calibrate the SWR meter after each adjust- ment of the antenna. WARNING: In order to avoid any losses and attenuations in cables used for connection between the radio and its accessories, PRESI- DENT recommends to use a cable with a length inferior to 3m. Your radio is now r

28、eady for use. B) HOW TO USE YOUR RADIO 1) ON/OFF VOLUME a) To turn the set on, turn the VOL knob (1) clockwise. b) To increase the sound level, turn the same knob further clockwise. 2) ASC (Automatic Squelch Control) / SQUELCH Suppresses undesirable background noises when there is no com- munication

29、. Squelch does not affect neither sound nor transmission power, but allows a considerable improvement in listening comfort. a) ASC: AUTOMATIC SQUELCH CONTROL Worldwide patent, a PRESIDENT exclusivity Turn the SQ knob (2) anti-clockwise into ASC position. ASC appears on the display. No repetitive man

30、ual adjustment and a permanent improvement between the sensitivity and the listening comfort when ASC is active. This function can be disconnected by turning the switch clockwise. In this case the squelch adjustment becomes manual again. ASC disappears from the display. b) MANUAL SQUELCH Turn the SQ

31、 knob (2) clockwise to the exact point where all back- ground noise disappears. This adjustment should be done with precision as, if set to maximum (fully clockwise), only the strongest signals will be received. 3) RF GAIN Adjustment of the sensitivity during reception. For long distance com- munica

32、tions should be set to maximum. You can reduce English 7 the RF GAIN in order to avoid distortion when your correspondent is close by and when he has no RF POWER. The normal setting of this function is on maximum (fully clockwise). 4) RF POWER Nonfunctional on the JFK II A+ model. 5) CHANNEL SELECTO

33、R: rotary knob and UP/DN keys on the microphone These switches allow increasing or decreasing a channel. A beep sounds each time the channel changes if the Beep function is activated. See BEEP function page 10. 6) DISPLAY It shows all functions: The BARGRAPH shows the reception level, the output pow

34、er level or SWR level. 7) SWR M5 SWR Allows changing the function of the meter. By pressing the SWR key (7) you alternate between SWR and S/RF. SWR: shows the SWR value on the display (scale from 1 to 3) S/RF: shows the output and reception power on the S/RF-meter. M5 Nonfunctional on the JFK II A+

35、model. 8) CH 19/9 FRQ M4 Nonfunctional on the JFK II A+ model. 9) MODE SELECTOR AM/FM PA M1 AM/FM (short press) Press AM/FM key (9) allows select AM or FM modulation. Your modu- lation mode has to correspond to the one of your correspondent. Amplitude modulation/AM: is for communications in areas wh

36、ere there are obstacles and over medium distances. Frequency modulation/FM: for nearby communications in fl at, open fi eld. PA (Public Address) (long press) An external sound loudspeaker can be connected on the PRESI- DENT JFK II A+ ASC by a jack located on the rear panel PA.SP (D). A long press al

37、lows alternate between Public Address and radio mode. In PA mode, PA appears on the display; the message sent in the microphone will be transferred to the external loudspeaker and amplifi ed. Keep the microphone at a suffi cient distance from this loudspeaker in order to avoid the Larsen effect. The

38、 PA volume is adjustable by the MIC GAIN button. Visual display of the level on the bargraph. M1 Nonfunctional on the JFK II A+ model. 10) ROGER M2 ROGER (short press) The icon appears on the display when the function is active. The ROGER BEEP sounds when the PTT (17) switch of the microphone is rel

39、eased in order to let your correspondent speak. Historically as radio is a simplex communication mode, it is not possible to speak and to listen at the same time (as it is the case with a telephone). Once someone had fi nished talking, he said “Roger” in order to prevent his correspondent that it wa

40、s his turn to talk. The word “Roger” has been replaced by a signifi cant beep. There comes “Roger beep” from. Note: the ROGER BEEP also sounds in the loudspeaker if the BEEP function is active. If the BEEP function is not active, only the cor- respondent can hear the ROGER BEEP. English 8 M2 Nonfunc
