Yaesu FT-2000/D User Manual

Introduction
This manual provides technical information necessary
for servicing the FT-2000/D HF/50 MHz Transceiver.
Servicing this equipment requires expertise in handling
surface-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 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 re-
ferred to by the type of the majority of components in-
stalled 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 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 technical
information would be appreciated.
