2、rounding for Electrical Safety Connect the rear panel ground lug to a good earth ground. For best performance, such a ground should consist of one or more ground rods 2.6 m (8 feet) long, connected to the transceiver via a low-inductance cable such as a heavy braided wire (the shield from sur- plus/

3、discarded RG-213 type cable is ideal). The lead-in cable should be as short as pos- sible. Do not use gas lines as a ground connection! Electrical Shock Prevention Be certain that all station wiring is properly insulated so as to prevent short-circuits which could damage this transceiver and/or acce

4、ssories connected to it. Be sure to protect power cables from damage due to abrasion by ensuring that they cannot be walked upon nor crushed under rolling chairs, etc. Never route power cables near sharp metallic edges which might cut through protective insulation. Never spill liquids into this tran

5、sceiver, and do not drop metallic objects into the trans- ceiver enclosure. Electrical shock may result when you attempt to remove the object. Unsupervised children should be kept away from any electrical apparatus such as the VX- 1400 Transceiver and its accessories. INSTALLATION VX-1400 OPERATING

6、MANUAL8 Antenna Precautions Always locate antennas such that they can never come in contact with outdoor power lines in the event of a catastrophic antenna support or power line support structure failure. Ground the support structure adequately, so as to dissipate energy absorbed during a light- nin

7、g strike. Install appropriate lightning arrestors in the antenna lead-in and rotator cable (if used) according to the arrestors instructions. In the event of an approaching electrical storm, disconnect all antenna lead-in, rotator cables, and power cables completely from your station if the storm is

8、 not immediately in your area. Do not allow disconnected cables to touch the case of your VX-1400 trans- ceiver or accessories, as lightning can easily jump from the cable to the circuitry of your transceiver via the case, causing irreparable damage. If a lightning storm is in progress in your immed

9、iate area, do not attempt to disconnect the cables, as you could be killed in- stantly if lightning should strike your antenna structure or a nearby power line. If a vertical antenna is utilized, be certain that humans and/or pets and farm animals are kept away both from the radiating element (to pr

10、event electrical shock and RF exposure 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 of the antenna in the event of a direct lightning strike. Heat and Ventilation To ensur

11、e long life of the components, be certain to provide adequate ventilation around the cabinet of the VX-1400. The cooling system of the transceiver must be free to draw cool air in from the bottom of the transceiver and expel warm air from the rear of the transceiver. Do not install the transceiver o

12、n top of another heat-generating 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 heating vents and window locations that could expose the transceiver to excessive direct sunlight

13、, especially in hot climates. INSTALLATION SAFETY PRECAUTIONS 9VX-1400 OPERATING MANUAL Electromagnetic Compatibility and RF Exposure If this transceiver is used with or in the vicinity of a computer or computer-driven acces- sories, you may need to experiment with grounding and/or radio frequency i

14、nterference (RFI) suppression devices (such as ferrite cores) to minimize interference to your commu- nications caused by energy leakage from the computer. Although there is negligible radio frequency (RF) leakage from the VX-1400 transceiver itself, its antenna system should be located as far away

15、from humans and animals as prac- ticable, 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 visually immediately upon opening the packing carton. Confirm that all controls an

16、d switches work freely, and inspect the cabinet for any damage. Gently shake the transceiver to verify that no internal components have been shaken loose due to rough handling during shipping. If any evidence of damage is discovered, document it thoroughly and contact the shipping company (or your l

17、ocal 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 punctures or other evidence of damage incurred during shipping; if it is necessary to return

18、 the unit for service or replacement, use the original packing materials but put the entire package inside another packing car- ton, so as to preserve the evidence of shipping damage for insurance purposes.

19、LLATION DC Power Connections The VX-1400 transceiver is designed for operation from 13.8 Volts DC, negative ground, with the DC source being capable of providing 23 Amperes of continuous current. For mobile applications, the fused (25-A) DC cable supplied with this transceiver may be used for making

20、 the power connections. Be absolutely certain to observe the proper polar- ity when making power connections: The RED DC power lead connects to the Positive (+) DC terminal; and the BLACK DC power lead connects to the Negative () DC terminal. To minimize noise pickup, and to provide the best input v

21、oltage stability for your trans- ceiver, 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 possible, and cut off any extra cable (from the battery end) to minimize voltage

22、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 splice (heat shrink tubing plus black electrical tape work well). INSTALLATION

24、the voltage across the battery terminals with the engine running fast enough to show a charge. If the voltage is above 15 Volts, the vehicles voltage regulator should be adjusted to reduce the charg- ing voltage below 14 Volts. ?With the radio end of the cable disconnected, connect the RED cable lea

25、d to the POSITIVE battery terminal, and the BLACK cable lead to the NEGATIVE battery terminal. Make certain that the battery terminal connections are tight, and remember to check them periodically for signs of loosening and/or corrosion. ?Make sure the POWER switch on the VX-1400 transceiver is off,

26、 and plug the DC cable into the INPUT jack on the rear panel of the transceiver. CAUTION! In mobile installations, check to ensure that the transceiver POWER switch is turned off whenever starting or stopping the engine, to avoid potential damage from switch- ing transients.

Complete installation instructions are pro- vided with the brac

28、ket. Mobile Antenna Considerations The VX-1400 transceiver is designed for use with any antenna system providing a 50- Ohm resistive impedance at the desired operating frequency. While minor excursions from the 50-Ohm specification are of no consequence, the power amplifiers protection cir- cuitry w

29、ill begin to reduce the power output if there is more than a 50% divergence from the specified impedance (less than 25 Ohms 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 frequencies on which ope

30、ration will take place, and the design of the antenna(s) in use. If your mobile or marine operation requires wide frequency coverage, the optional YA- 007FG (Frequency range is 7 MHz - 30 MHz) or similar mobile whip antenna may be used in conjunction with the optional FC-40 External Antenna Tuner. T

31、he FC-40 is de- signed to accommodate a wide variety of whip impedances at the operating frequency, converting these to the desired 50 ohm impedance via a sophisticated microprocessor- controlled impedance matching circuit. The FC-40 and VX-1400 provide memory of antenna matching settings sufficient

32、 for all channels on Memory Bank 1. In marine appli- cations, the FC-40 is also ideal for the use with a “backstay” antenna or marine mobile whip. INSTALLATION Install the ferrite core as close to connector as possible. Wrap the ends of the waterproof cap with sealing tape to protect against moistur

33、e ingress. IMPORTANT When connecting optional equipment, you must turn off the transceiver. 13VX-1400 OPERATING MANUAL The FC-40 should 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 th

34、e 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 as a counterpoise for the FC-40 and antenna radiating element. Be sure to weatherproof all outdoor connections thoroughly, especially in maritime environments. Complet

35、e the installation by connecting the RF coaxial cable and FC-40 control cable as shown in the pictorial below. Complete installation instructions are found in the FC-40 Instruction Manual; follow the manufacturers installation instructions when using a whip antenna other than the YA-007FG. For exten

36、ding the operating frequency range of an antenna fed with coaxial cable, the optional FC-30 Antenna Tuner may also be used. The impedance matching range of the FC-30 is from 17 Ohms to 150 Ohms. Interconnection guidelines may be found in the Operating Manual for the FC-30. MOBILE MOUNTING INSTALLATI

37、ON IMPORTANT When connecting optional equipment, you must turn off the transceiver. Note: The Mounting Bracket attached to the FC-30 is not used with the VX-1400.

38、les negative lead and the antenna systems coaxial cable shield, it may be necessary, in some installations, to provide a direct ground connection at the mounting location of the trans- ceiver. Due to unexpected resonances which may naturally occur in any location, im- proper communication system per

39、formance 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 communications installatio

40、n. The VX-1400 includes extensive filtering 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-1400 transceiver to the vehicle or vessels ground system should clear u

41、p any such difficulties. 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 described above. INSTALLATION

42、MOBILE MOUNTING 15VX-1400 OPERATING MANUAL BASE STATION INSTALLATION DC Power Connections For base station installations, Vertex Standard recommends the use of the optional FP- 1030A AC Power Supply. The FP-1030A provides a regulated 13.8 V DC supply at up to 25-Ampere. Other models of DC power supp

43、lies may be used with the VX-1400, but the 13.8 V DC input voltage, 23-Ampere current capability, and DC cable polarity guidelines described previously must be strictly followed. ?If you are connecting the FP-1030A with the VX-1400 for the first time, before connecting power check the label in the r

44、ear of the FP-1030A which indicates the AC mains voltage for which the supply is currently set. CAUTION! Permanent damage can result if improper supply voltage is applied to this trans- ceiver. Your warranty does not cover damage caused by application of AC, reversed polar- ity DC, or DC outside of

45、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-1400 wiring configuration. Other manufacturers may utilize power supplies with a physically matched connector that is wired differently; this will

47、rmance is critical to base station communications system effectiveness. Every effort must be made to ensure that the im- pedance of the antenna system utilized with the VX-1400 is as close as practicable to the specified 50-Ohm impedance value, and that mechanical and electrical component integ- rit

48、y are maintained at all times. For wide frequency range applications, Vertex Standards Model YA-30 Broadband Di- pole Antenna may be ideal for your communication requirements. Covering an operating frequency range of 1.6-30 MHz, the YA-30 eliminates the need for multiple antennas which might otherwise be required for equivalent frequency coverage. The type of antenna required for a particular communications distance will vary.
