FTM-10R/E
Technical Supplement
Introduction
This manual provides technical information necessary for
servicing the FTM-10R/E VHF/UHF FM 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 dou-
ble-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, VERTEX STANDARD 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.
Important Note
The 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 appara-
tus. 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.
