Introduction

This manual provides technical information necessary for

servicing the VX-6000U UHF FM Transceiver.

Servicing this equipment requires expertise in handling sur-

face-mount chip components. Attempts by non-qualified per-
sons to service this equipment may result in permanent damage
not covered by the warranty, and may be illegal in some coun-
tries.

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.

Important Note

After Lot. 13 of this transceiver was 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.
