Service Manual
©2004 VERTEX STANDARD CO., LTD.
This manual provides technical information necessary for servicing the VX-410/-420 series FM Transceiver.
Servicing this equipment requires expertise in handling surface-mount chip components. Attempts by non-qualified
persons to service this equipment may result in permanent damage not covered by the warranty, and may be illegal in
some countries.
Two PCB layout diagrams are provided for each double-sided circuit board in the transceiver. Each side of is referred
to by the type of the majority of components installed on that side ("leaded" or "chip-only"). In most cases one side has
only chip components, and the other has either a mixture of both chip and leaded components (trimmers, coils, electrolytic
capacitors, ICs, etc.), or leaded components only.
While we believe the technical information in this manual to be correct, VERTEX STANDARD assumes no liability
for damage that may occur as a result of typographical or other errors that may be present. Your cooperation in pointing
out any inconsistencies in the technical information would be appreciated.

  • Page 15: Alignment

    Introduction The VX-410/-420 series has been aligned at the fac- tory for the specified performance across the entire fre- quency range specified. Realignment should therefore not be necessary except in the event of a component failure. All component replacement and service should be per- formed only by an authorized Vertex Standard representa- tive, or the warranty policy may be voided.
