Introduction
This manual provides technical information necessary
for servicing the FT
1200 HF/50 MHz Transceiver.
DX
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.
While we believe the technical information in this
manual to be correct, YAESU MUSEN assumes no
liability for damage 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 information would be appreciated.
1) This transceiver was assembled using Pb (lead) free solder, based on the RoHS specification.
Only lead-free solder (Alloy Composition: Sn-3.0Ag-0.5Cu) should be used for repairs performed on this ap-
paratus. The solder stated above utilizes the alloy composition required for compliance with the lead-free
specification, and any solder with the above alloy composition may be used.
2) Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instruc-
tions.
