VHF FM Transceiver
VX-160V/-180V
Service Manual
©2002 VERTEX STANDARD CO., LTD. Printed in Japan.
Introduction
This manual provides technical information necessary for servicing the VX-160V and VX-180V 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, electrolyt-
ic 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.
