EVX-534/-539 VHF Service Manual 1

Introduction

This manual provides technical information necessary for servicing the

EVX-534/-539 VHF Hand-Held Digital/Analog Transceiver.

Servicing this equipment requires expertise in handling surface-mount

chip components. Attempts by non-qualied persons to service this equip-

ment 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 ma-

jority 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 in-

formation would be appreciated.

Important Note

This transceiver is assembled using Pb (lead) free solder, based on the RoHS specication.

Only lead-free solder (Alloy Composition: Sn-3.0Ag-0.5Cu) should be used for repairs performed on this appa-

ratus. The solder stated above utilizes the alloy composition required for compliance with the lead-free specica-

tion, and any solder with the above alloy composition may be used.
