VXR-7000 UHF Service Manual
Introduction
This manual provides technical information necessary for servicing the VXR-7000 FM Land Mobile Repeater.
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 repeater. 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.
Important Note
After Lot. 78 of this transceiver is assembled using Pb (lead) free solder, based on the RoHS specification.
Only lead-free solder (Alloy Composition: Sn-3.0Ag-0.5Cu) should be used for repairs performed on this apparatus. The
solder stated above utilizes the alloy composition required for compliance with the lead-free specification, and any solder with
the above alloy composition may be used.
