21、uld not be located in the vicinity of overhead power lines, other electric light or power circuits, where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them may

22、 be fatal. 15. OverloadingDo not overload wall out- lets and extension cords as this can result in a risk of fire or electric shock. 16. Object and Liquid EntryNever push objects of any kind into this product through openings as they may touch dangerous volt- age points or short-out parts that could

23、 result in a fire or electric shock. Never spill liquid of any kind on the product. 17. ServicingDo not attempt to service this product yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to quali- fied service personnel. 18. Damage Requir

24、ing ServiceUnplug this product from the wall outlet and refer servicing to qualified service personnel under the fol- lowing conditions: a. When the power-supply cord or plug is damaged. b. If liquid has been spilled, or objects have fallen into the product. c. If the product has been exposed to rai

25、n or water. d. If the product does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions. An improper adjust- ment may result in damage and will often require extensive work by a qualified technician to restore the pro

26、duct to its normal operation. e. If the product has been dropped or the cabinet has been damaged. f. When the product exhibits a distinct change in performancethis indicates a need for service. 19. Replacement Partswhen replacement parts are required, be sure the service techni- cian has used replac

27、ement parts specified by the manufacturer or have the same character- istics as the original parts. Unauthorized sub- stitutes may result in fire, electric shock or other hazards. 20. Safety ChecksUpon completion of any service or repairs to this product, ask the service technician to perform safety

28、 checks to determine that the product is in proper operat- ing condition. 21. Outdoor Antenna GroundingBefore attempting to install this product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. a. Use No.10 AWG copp

29、er, No.8AWG alumi- num, No.17AWB copper-clad steel or bronze wire or larger, as ground wire. b. Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4 feet to 6 feet apart. c. Mount antenna discharge unit as close as possible to where lead-in enters house. d. A driv

30、en rod may be used as the grounding electrode where other types of electrode systems do not exist. Refer to the National Electric Code, ANSI/NFPA 70-1990 for infor- mation. e. Use jumper wire not smaller than No.6 AWG copper or equivalent, when a separate antenna grounding electrode is used. 4 Table

The wire from the ground rod connects to the wing nut or to the Black terminal on the antenna connector block on the back of the radio. The wire used in an outdoor antenna needs to be strong enou

33、gh to support its own weight, as well as to hold up any additional weight such as ice from an ice storm. Normally, 14 gauge or larger is considered an adequate size, especially if the wire is copper- clad steel especially designed for antenna use. If the far end of the antenna is supported by a tree

34、 or other support that sways in the wind, a pulley and weight arrangement will prevent the swaying from putting additional strain on the wire. WARNING: Any outdoor antenna MUST be located so that it cannot fall on power lines or power lines cannot fall on it, if they should come down. Also, any outd

35、oor antenna MUST have an approved lightning arrestor, installed in accordance with ap- plicable building and electrical codes, at the point where the antenna connection enters the building. 22 Antennas 1-800-773-7931 WWW.PALSTAR.COM erly hear the audio, a local replacement for the carrier is provide

36、d by the BFO. The USB and LSB mode buttons on the front of your Palstar R30A are pre-tuned and optimized BFO settings for the reception of Upper and Lower Sideband signals. You must choose the cor- rect one: listening to USB in the LSB mode or vice-versa will result in more distortion. To avoid conf

37、usion over which to use, Hams by agreement use LSB on 160, 80, and 40 Meters, and USB on the bands above that. Shortwave broadcasters tend to use USB. Having chosen the correct USB or LSB setting, as you tune across a SSB signal the audio pitch will change, and you will reach a point where the voice

38、 becomes understandable, and it finally will reach a normal sounding pitch. If you continue to tune past, the pitch will again change. ANTENNAS Previously we talked about the relationship between frequency and wavelength. Antennas work best when their length is a signifi- cant fraction (i.e. 1/4 or

39、1/2) of a wavelength. That means that an antenna gives its ideal best performance on only one frequency. Since the Palstar R30A receives from 100 kHz to 30 MHz, the range of wavelengths it covers is from 3000 Meters to 10 Meters, so no single antenna can give optimal performance on all frequen- cies

40、. Fortunately, receiving antennas are less demanding than transmit- ting antennas, and adequate performance can be had with quite simple arrangements. If you live in an ordinary frame or brick home, surprisingly good results can be had with a wire strung around the walls of a room. Just strip 1/4 (1

41、0 mm) or so of the insulation from one end and connect it to the Red terminal on the antenna terminal block on the back of the R30A. The wire can be simple 22 gauge insulated hookup wire. If you dont have a metal roof, effective wire antennas can also be strung in attics. You may desire the improved

42、 performance that an outdoor an- tenna provides, or, if you live in a steel-reinforced or metal-sided building, it may be too shielded for an indoor antenna to work well. Performance of the antenna will be improved by providing an earth connection to a ground stake. For best results, get a good qual

To return to channel number display, once again press the Tuning Knob until it clicks. To return to Normal Mode, pres

This is used when it is necessary to monitor a specific frequency, and you want to be sure the tuning cannot be changed by inadvertently bumping the contr

45、ols or by vibration. After tuning in the desired station, to engage Frequency Lock Mode, press in and hold the Tuning Knob for 2 seconds. The Digital Display will show “LOCDIS” to indicate that the frequency cannot be changed. To release the Frequency Lock, once again press in and hold the Tuning Kn

46、ob for 2 seconds. If the R30A is powered down while the frequency is locked, it will still be locked when powered up again. 3.
