Realignment should therefore not be necessary except in the event of a compon

11、ent fail- ure. All component replacement and service should be performed only by an authorized VERTEX STANDARD representative, or the warranty policy may be voided. The following procedures cover the sometimes critical and tedious adjustments that are not normally required once the transceiver has l

12、eft the factory. However, if dam- age occurs and some parts are replaced, realignment may be required. If a sudden problem occurs during normal operation, it is likely due to component failure; realign- ment should not be done until after the faulty compo- nent has been replaced. We recommend that s

13、ervicing be performed only by authorized VERTEX STANDARD service technicians, who are experienced with the circuitry and fully equipped for repair and alignment. Therefore, if a fault is suspected, contact the dealer from whom the trans- ceiver was purchased for instructions regarding repair. Author

14、ized VERTEX STANDARD service technicians realign all circuits and make complete performance checks to ensure compliance with factory specifications after replacing any faulty components. Those who do undertake any of the following align- ments are cautioned to proceed at their own risk. Prob- lems c

15、aused by unauthorized attempts at realignment are not covered by the warranty policy. Also, VERTEX STANDARD must reserve the right to change circuits and alignment procedures in the interest of improved performance, without notifying owners. Under no circumstances should any alignment be at- tempted

16、 unless the normal function and operation of the transceiver are clearly understood, the cause of the mal- function has been clearly pinpointed and any faulty com- ponents replaced, and the need for realignment deter- mined to be absolutely necessary.

19、fter completing one step, read the next step to see if the same test equipment is required. If not, re- move the test equipment (except dummy load and watt- meter, if connected) before proceeding. Correct alignment requires that the ambient tempera- ture be the same as that of the transceiver and te

20、st equip- ment, and that this temperature be held constant between 6886F (2030C). When the transceiver is brought into the shop from hot or cold air, it should be allowed some time to come to room temperature before alignment. Whenever possible, alignments should be made with os- cillator shields an

21、d circuit boards firmly affixed in place. Also, the test equipment must be thoroughly warmed up before beginning. Note: Signal levels in dB referred to in the alignment proce- dure are based on 0 dB=0.5 V (closed circuit). 8VX-8R/E and VX-8DR/E Technical Supplement Alignment Internal System Alignmen

22、t Routine This uses a programmed routine in the transceiver which simplifies many previously complex discrete com- ponent settings and adjustments with digitally-con- trolled settings via front panel buttons and LCD indica- tions. 1. To begin, set the transceiver to the VFO mode on the A-Band in the

23、 Mono band mode. 2. Program a password for the Alignment (AH029M) ac- cording to the following procedure: 1) Press and hold the MENU key for one second to enter the Set mode. 2) Rotate the DIAL knob to select Set Mode Item 21: CW ID. 3) Press the MENU key briefly to enable adjustment of this Set Mod

24、e Item. 4) Rotate the DIAL knob to select ON. 5) Press the MODE key, then press and hold in the HM/RV key for two seconds to clear any previous entry. 6) Program the password AH029M using the DIAL knob (select the character), and BAND/MODE key (move the cursor). 7) When you have completed the passwo

25、rd, press the MENU key briefly, then press the PTT switch to exit to normal operation. Remember to delete the password AH029Mfrom the Set Mode Item 21: CW ID when the alignment adjust- ments are finished by pressing and holding in the HM/ RV key for two seconds (as in step 5 above). 3. Press the PWR

26、 switch for two seconds to turn the transceiver off. 4. Press and hold in the HM/RV key while powering the transceiver on again. The transceiver will enter the adjustment mode, and the display will show the first alignment setting. Thereafter, the frequencies used during alignment will automatically

27、 be set without action by the technician. DIAL V/M V/M HM/RV As each transceiver is individually optimized at the factory, the precise settings for the transceiver on your bench may be slightly different.
