Service Manual
Introduction
This manual provides technical information necessary for servicing the VX-1210 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 thr board 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.
