1、2003 VERTEX STANDARD CO., LTD. E126990A Technical Supplement VX-5R 50/144/430 MHz Triple-Band Heavy Duty FM Transceiver Introduction This manual provides the technical information necessary for servicing the VX-5R Triple-Band Heavy Duty FM Transceiver. Servicing this equipment requires expertise in
2、handing surface-mount chip components. Attempts by non-qualified persons to service this equipment may result in permanent damage not covered by the war- ranty, and may be illegal in some countries. Two PCB layout diagrams provided for each double-sided board in this transceiver. Each side of the bo
3、ard is referred to by the type of the majority of components installed on that side (Side A or Side B). In most cases one side has only chip components, and the other has ei- ther a mixture of both chip and leaded components (trimmers, coils, electrolytic capacitors, ICs, etc.), or leaded components
4、 only. While we believe the information in this manual to be correct, VER- TEX STANDARD assumes no liability for damage that may occur as a result of typographical or other errors that may be present. Your coop- eration in pointing out any inconsistencies in the technical informa- tion would be appr
5、eciated. Contents Specification. 2 Exploded View realignment should not be done until after the faulty com- ponent has been replaced. The following procedures cover the adjustments that are not normally required once the transceiver has left the factory. However, if damage occurs and some parts sub-
6、 sequently are replaced, realignment may be required. We recommend that servicing be performed only by au- thorized VERTEX STANDARD service technicians who are experienced with the circuitry and fully equipped for repair and alignment. If a fault is suspected, contact the dealer from whom the transc
7、eiver was purchased for in- structions regarding repair. Authorized VERTEX STAN- DARD service technicians realign all circuits and make complete performance checks to ensure compliance with factory specifications after replacing any faulty compo- nents. Those who do undertake any of the following al
8、ign- 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, Yaesu reserves the right to change circuits and alignment procedures in the interest of improved performance, without notifying owners. Under
9、 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 realignment determined to be ab- solutely necessary. The foll
10、owing test equipment (and familiarity with its use) is necessary for complete realignment. Correction of problems caused by misalignment resulting from use of improper test equipment is not covered under the war- ranty policy. While most steps do not require all of the equipment listed, the interact
11、ions of some adjustments may require that more complex adjustments be performed afterwards. Do not attempt to perform only a single step unless it is clearly isolated electrically from all other steps. Have all test equipment ready before beginning and, follow all of the steps in a section in the or
12、der presented.

After performing the system alignment in its entirety, in- dividual settings can be returned to and adjusted should the need arise. In the section to follow, typical default values (
15、as set at the factory) are shown in brackets (e.g. 119), to serve as a general guideline. As each transceiver is individually op- timized at the factory, the precise settings for the trans- ceiver on your bench may be slightly different. 50 MHz Band Alignment Squelch Hysteresis Adjustment (HIS SQL)
