9、ed ama- teur bands. Realignment should therefore not be neces- sary except in the event of a component failure. All com- ponent 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 s

10、ometimes critical and tedious adjustments that are not normally required once the transceiver has left 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

11、- ment should not be done until after the faulty compo- nent has been replaced. We recommend that servicing 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, con

12、tact the dealer from whom the trans- ceiver was purchased for instructions regarding repair. Authorized 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 u

13、ndertake any of the following align- ments are cautioned to proceed at their own risk. Prob- lems caused 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 improve

14、d performance, without notifying owners. Under no circumstances should any alignment be at- tempted 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 re

15、alignment deter- mined to be absolutely necessary.

If not, re- move the test equipment (except dummy load and watt- meter, if connected) before proceeding. Corr

18、ect alignment requires that the ambient tempera- ture be the same as that of the transceiver and test 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 temp

19、erature before alignment. Whenever possible, alignments should be made with os- cillator shields and 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.

21、 indica- tions. 1. To begin, set the transceiver to the VFO mode on the A-Band in the Mono band mode. 2. Program a password for the Alignment (AH041M) 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 Mo

22、de Item 16: CW ID. 3) Press the MENU key briefly to enable adjustment of this Set Mode 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 AH041M using the DIAL knob (select the c

23、haracter), and BAND/MODE key (move the cursor). 7) When you have completed the password, press the MENU key briefly, then press the PTT switch to exit to normal operation. Remember to delete the password AH041Mfrom the Set Mode Item 16: CW ID when the alignment adjust- ments are finished by pressing

24、 and holding in the HM/ RV key for two seconds (as in step 5 above). 3. Press the PWR 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 al

25、ignment setting. Thereafter, the frequencies used during alignment will automatically be set without action by the technician.
