Be sure to pro- tect power cables from damage due to abrasion by ensur- ing that they cannot be walked upon nor crushed under rolling chairs, etc. Never route power cables near

5、sharp metallic edges which might cut through protective insula- tion. Never spill liquids into this transceiver, and do not drop metallic objects into the transceiver enclosure. Electrical shock may result when you attempt to remove the object. Unsupervised children should be kept away from any elec

INSTALLATION Antenna Precautions Always locate antennas such that they can never come in contact with outdoor power lines in the event of a cata- strophic antenna support or power line support structure failure. Ground the suppo

7、rt structure adequately, so as to dissipate energy absorbed during a lightning strike. In- stall appropriate lightning arrestors in the antenna lead-in and rotator cable (if used) according to the arrestors in- structions. In the event of an approaching electrical storm, discon- nect all antenna lea

8、d-in, rotator cables, and power cables completely from your station if the storm is not immedi- ately in your area. Do not allow disconnected cables to touch the case of your VX-1700 transceiver or accesso- ries, as lightning can easily jump from the cable to the circuitry of your transceiver via th

9、e case, causing irrepa- rable damage. If a lightning storm is in progress in your immediate area, do not attempt to disconnect the cables, as you could be killed instantly if lightning should strike your antenna structure or a nearby power line. If a vertical antenna is utilized, be certain that hum

10、ans and/or pets and farm animals are kept away both from the radiating element (to prevent electrical shock and RF ex- posure danger) and the ground system, in the event of an electrical storm. The buried radials of a ground-mounted vertical antenna can carry lethal voltages outward from the center

11、of the antenna in the event of a direct lightning strike. Heat and Ventilation To ensure long life of the components, be certain to pro- vide adequate ventilation around the cabinet of the VX- 1700. The cooling system of the transceiver must be free to draw cool air in from the bottom of the transce

12、iver and expel warm air from the rear of the transceiver. Do not install the transceiver on top of another heat-gen- erating device (such as a linear amplifier), and do not place equipment, books, or papers on top of the transceiver. Place the transceiver on a hard, flat, stable surface. Avoid heat-

13、 ing vents and window locations that could expose the trans- ceiver to excessive direct sunlight, especially in hot cli- mates. Page 6VX-1700 OPERATING MANUAL Electromagnetic Compatibility and RF Exposure If this transceiver is used with or in the vicinity of a com- puter or computer-driven accessor

14、ies, you may need to experiment with grounding and/or radio frequency inter- ference (RFI) suppression devices (such as ferrite cores) to minimize interference to your communications caused by energy leakage from the computer. Although there is negligible radio frequency (RF) leak- age from the VX-1

15、700 transceiver itself, its antenna sys- tem should be located as far away from humans and ani- mals as practicable, so as to avoid the possibility of shock due to accidental contact with the antenna or excessive long-term exposure to RF energy. Preliminary Inspection Inspect the transceiver visuall

16、y immediately upon open- ing the packing carton. Confirm that all controls and switches work freely, and inspect the cabinet for any dam- age. Gently shake the transceiver to verify that no inter- nal components have been shaken loose due to rough han- dling during shipping. If any evidence of damag

17、e is discovered, document it thor- oughly and contact the shipping company (or your local dealer, if the unit was purchased over-the-counter) so as to get instructions regarding the prompt resolution of the damage situation. Be certain to save the shipping carton, especially if there are any punctur

18、es or other evidence of damage incurred during shipping; if it is necessary to re- turn the unit for service or replacement, use the original packing materials but put the entire package inside an- other packing carton, so as to preserve the evidence of shipping damage for insurance purposes.

19、LATION Page 7VX-1700 OPERATING MANUAL POWER REQUIREMENTS AND BASIC INSTALLATION DC Power Connections The VX-1700 transceiver is designed for operation from 13.8 Volts DC, negative ground, with the DC source be- ing capable of providing 25 Amperes of continuous cur- rent. For mobile applications, the

20、 fused (25-A) DC cable sup- plied with this transceiver may be used for making the power connections. Be absolutely certain to observe the proper polarity when making power connections: The RED DC power lead connects to the Positive (+) DC terminal; and The BLACK DC power lead connects to the Negati

21、ve () DC terminal. To minimize noise pickup, and to provide the best input voltage stability for your transceiver, we recommend you connect the DC cable directly to the vehicle battery, rather than to the ignition or accessory circuitry. Route the DC cable as far away from ignition cables as possibl

22、e, and cut off any extra cable (from the battery end) to minimize voltage drop. If the DC cable is not long enough, use #12 AWG (minimum) stranded, insulated wire to extend it. Be absolutely certain to solder the connections at the splice securely, and provide ample insulation for the soldered splic

23、e (heat shrink tubing plus black electrical tape work well). Use the following procedure to connect the DC cable: ? Before connecting the DC cable to the battery, mea- sure the voltage across the battery terminals with the engine running fast enough to show a charge. If the voltage is above 15 Volts

24、, the vehicles voltage regu- lator should be adjusted to reduce the charging volt- age below 14 Volts. ? With the radio end of the cable disconnected, connect the RED cable lead to the POSITIVE battery termi- nal, and the BLACK cable lead to the NEGATIVE battery terminal. Make certain that the batte

25、ry termi- nal connections are tight, and remember to check them periodically for signs of loosening and/or corrosion. ? Make sure the POWER switch on the VX-1700 trans- ceiver is off, and plug the DC cable into the INPUT jack on the rear panel of the transceiver. CAUTION! In mobile installations, ch

26、eck to ensure that the transceiver POWER switch is turned off whenever start- ing or stopping the engine, to avoid potential damage from switching transients. 12V Battery Cigarette Lighter Plug Fuse Box REDBLACK VX-1700 FUSE: 25A INSTALLATION Page 8VX-1700 OPERATING MANUAL MOBILE MOUNTING The option

27、al MMB-89 Mobile Mounting Bracket allows quick insertion and removal of the VX-1700 transceiver from the vehicle. Complete installation instructions are provided with the bracket. Mobile Antenna Considerations The VX-1700 transceiver is designed for use with any antenna system providing a 50-Ohm res

28、istive impedance at the desired operating frequency. While minor excur- sions from the 50-Ohm specification are of no conse- quence, the power amplifiers protection circuitry will begin to reduce the power output if there is more than a 50% divergence from the specified impedance (less than 25 Ohms

29、or greater than 100 Ohms, corresponding to a Standing Wave Ratio (SWR) of 2.0:1). Compliance with this specification critically depends on the range of fre- quencies on which operation will take place, and the de- sign of the antenna(s) in use. If your mobile or marine operation requires wide freque

30、ncy coverage, the Yaesu YA-007FG or similar mobile whip antenna may be used in conjunction with the Yaesu FC- 40 External Antenna Tuner. The FC-40 is designed to accommodate a wide variety of whip impedances at the operating frequency, converting these to the desired 50 ohm impedance via a sophistic

31、ated microprocessor-con- trolled impedance matching circuit. The FC-40 and VX- 1700 provide memory of antenna matching settings suf- ficient for all channels on Memory Bank 1. In marine ap- plications, the FC-40 is also ideal for the use with a “backstay” antenna or marine mobile whip. The FC-40 sho

32、uld be located at or near the base of the antenna, so as to minimize losses and stray radiation. The short lead-in wire from the whip must be securely bonded both to the FC-40 and the antenna (whip or wire), and the FC-40 must be securely bonded to the vehicle or vessel ground system, which will act

33、 as a counterpoise for the FC-40 and antenna radiating element. Be sure to weath- erproof all outdoor connections thoroughly, especially in maritime environments. Complete the installation by connecting the RF coaxial cable and FC-40 control cable as shown in the pictorial below. Complete installati

34、on instructions are found in the FC-40 Instruction Manual; follow the manufacturers in- stallation instructions when using a whip antenna other than the YA-007FG. For extending the operating frequency range of an an- tenna fed with coaxial cable, the Yaesu model FC-30 Antenna Tuner may also be used.

35、 The impedance match- ing range of the FC-30 is from 17 Ohms to 150 Ohms. Interconnection guidelines may be found in the Operat- ing Manual for the FC-30. VX-1700 FC-30 INSTALLATION Page 9VX-1700 OPERATING MANUAL Mobile Station Grounding Although satisfactory grounding in most installations will be

36、achieved via the DC cables negative lead and the an- tenna systems coaxial cable shield, it may be necessary, in some installations, to provide a direct ground connec- tion at the mounting location of the transceiver. Due to unexpected resonances which may naturally occur in any location, improper c

37、ommunication system performance may result from insufficient grounding. These symptoms may include: RF feedback (resulting in distortion of your transmitted signal), unintended scanning, blinking or blanking of the frequency display, or loss of memory. Note that these conditions may occur in any com

38、munica- tions installation. The VX-1700 includes extensive filter- ing designed to minimize the chance of such problems; however, random currents set up by insufficient RF grounding can nullify such filtering. Bonding the rear panel GND terminal of the VX-1700 transceiver to the vehicle or vessels g

39、round system should clear up any such diffi- culties. Vertex Standard does not recommend the use of “on glass” mobile antennas unless the shield of the coaxial cable is securely grounded near the feedpoint of the antenna. Such antennas frequently are responsible for the ground-related difficulties d

40、escribed above. MOBILE MOUNTING INSTALLATION Page 10VX-1700 OPERATING MANUAL BASE STATION INSTALLATION DC Power Connections For base station installations, Yaesu recommends the use of the Model FP-1030A AC Power Supply. The FP- 1030A provides a regulated 13.8 V DC supply at up to 25 Ampere. Other mo

41、dels of DC power supplies may be used with the VX-1700, but the 13.8 V DC input voltage, 25 Ampere current capability, and DC cable polarity guidelines de- scribed previously must be strictly followed. ? If you are connecting the FP-1030A with the VX- 1700 for the first time, before connecting power

42、 check the label in the rear of the FP-1030A which indicates the AC mains voltage for which the supply is currently set. CAUTION! Permanent damage can result if improper sup- ply voltage is applied to this transceiver. Your warranty does not cover damage caused by application of AC, re- versed polar

43、ity DC, or DC outside of the specified range of 13.8 V 15%. If using a power supply other than the FP-1030A, ensure that the DC supply connector to the transceiver matches the VX-1700 wiring configuration. Other manufacturers may utilize power supplies with a physically matched connector that is wir

44、ed differently; this will cause serious damage to the VX-1700 transceiver!

45、e installations, antenna perfor- mance is critical to base station communications system effectiveness. Every effort must be made to ensure that the impedance of the antenna system utilized with the VX- 1700 is as close as practicable to the specified 50-Ohm impedance value, and that mechanical and

46、electrical com- ponent integrity are maintained at all times. For wide frequency range applications, Vertex Standards Model YA-30 Broadband Dipole Antenna may be ideal for your communication requirements. Covering an oper- ating frequency range of 1.6-30 MHz, the YA-30 elimi- nates the need for mult

47、iple antennas which might other- wise be required for equivalent frequency coverage. The type of antenna required for a particular communica- tions distance will vary. A complete discussion of this topic is beyond the range of this manual; however, a few gen- eral guidelines will be offered herewith

48、. Any antenna to be installed should be free of nearby ob- structions which might interfere with its radiation pattern. The antenna, its support structure, and its cables must never be installed in such a manner that would allow them to contact with power or telephone lines in the event of a catastr

49、ophic windstorm or other cause of major failure. An adequate safety is usually provided by keeping the antenna and its support structure 1.5 times the height of the support plus the length of any antenna or guy wires attached to the support. When installing a balanced antenna such as a dipole, re- member that the VX-1700 transceiver is designed for use with an (unbalanced) coaxial feedline. Always use a balun or other balancing device so as to ensure proper antenna system performance. Vertical antennas usually pr
