Liquid Crystal Display Panel: The liquid crystal panel provides the user with a visual information on the operation a

23、nd status of the AE 497 W. CAUTION: Due to the physical behaviour of LCDs, liquid crystal displays should not be subjected to extremes of temperature or humidity. If the unit is exposed to temperatures below -20C (-5F) or above + 60C ( +140F), the display may temporarily cease to function properly,

24、and in some cases, could result in permanent 8 damage. Do not subject radio to extreme conditions, such as closed automobile in direct sunlight or continuous sub zero temperatures. All liquid crystal displays have a preferred viewing angle when the display contrast is at a maximum. The best viewing

25、point will vary by user, depending on such variables as temperature, humidity, battery condition, and the actual users eyesight.

ANALOG INDICATOR METER: A B A S-TX METER: Indicates relative incoming signal strength and RF out put power. 9 B Modulati

29、on / SWR Meter: Measures the percent modulation of the AM signal. Note that the CAL/SWR/MOD switch must be in the “MOD” position for the meter to measure and read modulation. SWR METER: Measures the ratios of standing wave ratio of the antenna system, which is critical in properly adjusting the leng

30、th antenna and all related electrical connections. This meter will indicate if there are any major changes in these critical areas caused by such things as humidity, vibration, or corrosion, which will cause the SWR Meter to rise. A rising SWR indicates that a problem exists. To Calibrate SWR: a) Se

31、t the radio into the AM mode. b) Switch the CAL/SWR/MOD knob to the SWR position c) Transmit by pressing the PTT button on the microphone, and adjust the SWR/CAL, control until the needle reaches the CAL position on the meter. d) Put the CAL/SWR/MOD knob back to the SWR position, and read the SWR va

32、lue. INSTALLATION LOCATION OF THE RADIO Prior to beginning operation if the transceiver, a basic installation must be prepared. Installation of the transceiver itself is a rather simple procedure. In selecting the location for the unit, two basic factors must be considered: A. Access to 230V, 50Hz o

33、r 13,8V DC power source. B. The location must be convenient for running the antenna lead in cable if an outside antenna installation is proposed. BASE STATION ANTENNA Since the maximum allowable power output of the transmitter may be limited by the Regulations or Licence classes, the antenna is the

34、most important factor affecting transmission distance. Only a properly matched antenna will allow maximum power transfer from the 50 ohm transmission line to the radiating element. The recommended method of antenna turning is to use the built in SWR meter to adjust the antenna turning for maximum re

35、flected power. The radio may be used with any type of 50 ohm base station antenna. A ground plane vertical antenna will provide the most uniform horizontal coverage. This type of antenna is best suited for communication with a mobile unit. For point to point operation where both stations are fixed,

36、a directional beam will usually increase communicating range since this beam antenna also allows the receiver to “listen” in only one direction, thus reducing interfering signals. 10 OPERATING PROCEDURES TO RECEIVE 1. Turn the radio ON by pressing the POWER switch. 2. Press the “Mode” selection butt

37、on (labeled “5” on the button) continuously until you find the mode of operation you desire to operate in (AM, FM, USB, LSB). 3. Adjust the VOLUME control until you reach your desired listening level. 4. Turn the frequency selector knob to the desired operating frequency. 5. Turn the RF GAIN control

38、 completely clockwise. 6. Adjust the “CLARIFIER” control to clarify the SSB signals (start from middle position). 7. Listen to the background noise coming from the radio. Turn the squelch control slowly until the noise just disappears. (No signal should now be present). Leave the control at this set

39、ting. The SQUELCH is now properly adjusted. The receiver will remain quiet until a signal is actually received. Do not advance the knob too far, as some of the weaker signals will not be heard. OPERATING PRODEDURE TO TRANSMIT 1. Select the desired frequency of transmission. 2. Set the MIC GAIN contr

40、ol fully clockwise. 3. Activate the press to talk switch. The receiver and transmitter are controlled by the press to talk switch on the microphone. Press the switch and the transmitter is activated. Release the switch to receiver. 4. Hold the microphone two inches from your mouth, speak in a clear

41、normal voice. 5. The S-TX meter will indicate power output and the modulation meter will indicate percentage of modulation as you speak into the microphone. CAUTION: Be sure the antenna is properly connected to the radio before transmitting. Transmitting without an antenna or a poorly matched antenn

42、a could cause damage to the transmitter. RESEIVING SSB SIGNALS There are four types of signals presently used for communications in the Citizen Band: AM, FM, USB and LSB. When the MODE switch on your unit is placed in the AM position, only standard double sideband, fully carrier signals will be dete

43、cted. An SSB signal may be recognized while in the AM mode to produce an intelligible output. The USB and LSB modes will detect upper sideband an lower sideband respectively, and standard AM signals. 11 SSB reception differ from standard AM reception in that SSB receiver does not require a carrier o

44、r opposite sideband to produce an intelligible signal. A single sideband transmitted signal consists only of the upper or the lower sideband and no carrier is transmitter. The eliminate of the carrier from the AM signal helps to eliminate the biggest cause of whistles and tones heard on channels whi

45、ch make even moderately strong AM signals unreadable. Also, SSB take only half of an AM mode therefore two SSB conversations will fit into each frequency, expanding the two time frequency. The reduction in channel space required also helps in the receiver because only half of the noise and interfere

46、nce can be received with 100% of the SSB signal. An SSB signal may be received only when the listening receiver is functioning in the same mode. In other words, an Upper Sideband Signal (USB) may be made intelligible only if the receiver is functioning in the USB position. If a Lower Sideband (LSB)

47、signal is heard when the receiver is in the USB mode, no amount of turning will make the signal intelligible. The reason for this may be understood if you consider that when the modulation is applied to the transmitters microphone in the USB mode, the transmitters output frequency is increased where

48、as in the LSB mode the transmitters output frequency is decreased. The result in listening to the receiver is that when the MODE switch is in the proper position (either USB or LSB), a true reproduction of single tone of modulation will result, and if the tone is increased in frequency (such as a lo

49、w pitched whistle or a high pitched whistle) you will hear the increase in the output tone of the receiver. If the incorrect mode is selected, an increase in tone of a whistle applied to the transmitter will cause a decrease in the resultant tone from the receiver. Thus when a voice is used in place of a whistle or a tone, in the proper listening mode the v
