#Yaesu service manuals manual
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. 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. Each side of is referred to by the type of the majority of components installed on that side (leaded or chip-only). Two PCB layout diagrams are provided for each double-sided circuit board in the Transceiver. 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. Servicing this equipment requires expertise in handling surface-mount chip components.
