This manual provides the technical information
necessary for servicing the FT-51R Dual-Band hand­
held 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 are 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 ("leaded" or "chip­
only"). In most cases one side has only chip compo-
FT-51R Technical Suoolement
nents, and the other has either a mixture of both chip
and leaded components (trimmers, coils, electrolytic
capacitors, ICs, etc.), or leaded components only.
While we believe the information in this manual to
be correct, Yaesu Musen assumes no liability for dam­
age that may occur as a result of typographical or
other errors that may be present. Your cooperation in
pointing out any inconsistencies in the technical in­
formation would be appreciated.
Yaesu Musen reserves the right to make changes in
this transceiver in the interest of technological im­
provements, without notification to the owners.
