This manual provides technical information necessary for
servicing the FT-8800R Transceiver.
Servicing this equipment requires expertise in handling
surface-mount chip components. 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.
Two PCB layout diagrams are provided for each double-sided
circuit board in the transceiver. Each side of thr board is
referred to by the type of the majority 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.
