IntroductionThis manual provides technical information necessaryfor servicing the FT-2000/D HF/50 MHz Transceiver.Servicing this equipment requires expertise in handlingsurface-mount chip components. Attempts by non-qual-ified persons to service this equipment may result in per-manent damage not covered by the warranty, and maybe illegal in some countries.Two PCB layout diagrams are provided for each double-sided circuit board in the Transceiver. Each side of is re-ferred to by the type of the majority of components in-stalled on that side (“leaded” or “chip-only”). In mostcases one side has only chip components, and the otherhas either a mixture of both chip and leaded components(trimmers, coils, electrolytic capacitors, ICs, etc.), or lead-ed components only.While we believe the technical information in this man-ual to be correct, VERTEX STANDARD assumes no lia-bility for damage that may occur as a result of typograph-ical or other errors that may be present. Your coopera-tion in pointing out any inconsistencies in the technicalinformation would be appreciated.©2007 VERTEX STANDARD CO., LTD.
