1、EVX-5300/-5400 UHF Service Manual1 Introduction This manual provides technical information necessary for servicing the EVX-5300/-5400 UHF Digital/Analog Mobile Trans- ceiver. Servicing this equipment requires expertise in handling surface-mount chip components. Attempts by non-qualiied persons to se

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

3、side (“leaded” or “chip-only”). In most cases one side has only chip com- ponents, 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

4、design of the EVX-5300/-5400 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 FIF-12 USB Programming Interface and CE142 Software. While we believe the te

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
