Dual Band Digital Transceiver
FT3DR/FT3DE
Introduction
This manual provides the technical information necessary for
servicing the FT3DR/FT3DE 144/430 MHz Dual Band Digital
Transceiver.
Servicing this equipment requires expertise in handing 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.
While we believe the information in this manual to be correct,
YAESU 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.
Caution
Risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries according to the instructions.
Important Note
This transceiver was assembled using Pb (lead) free sol-
der, based on the RoHS specification.
Only lead-free solder (Alloy Composition: Sn-3.0Ag-0.5Cu)
should be used for repairs performed on this apparatus.
The solder stated above utilizes the alloy composition re-
quired for compliance with the lead-free specification, and
any solder with the above alloy composition may be used.
