Informationen:
This manual provides technical information necessary for
servicing the FT-897 HF/VHF/UHF ALL MODE 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 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.
