The manual provides the technical information necessary for
servicing the FT-8100R Dual-Band mobile amateur 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 provided for each double-sided board
in this transceiver. Each side of the board is referred to
by the type of the majority of components installed on that
side ("lead-ed" 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.
