Introduction
This manual provides the technical information necessary for servicing the VXR-9000 Rack Mount Repeater.
Servicing this equipment requires expertise in handing 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 board in this transceiver. Each side of the board 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 (surface-mount devices), and the other has either a mixture of both chip and leaded
components (trimmers, coils, electrolytic capacitors, ICs, etc.), or leaded components only.
As described in the pages to follow, the advanced microprocessor design of the VXR-9000EV allows a complete
alignment of this transceiver to be performed without opening the case of the radio; all adjustments can be performed
from the personal computer, using with the Vertex Standard VPL-1 Programming Cable and CE60 Software.
While we believe the 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.
