HF/50 MHz TRANSCEIVER

FT-710

Introduction

This manual provides the technical information necessary 
for servicing the FT-710 HF/50 MHz 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.
While we believe the information in this manual to be cor-

present. Your cooperation in pointing out any inconsisten-
cies in the technical information would be appreciated.

Important Note

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 apparatus. The solder stated 

above utilizes the alloy composition required for compliance with the lead-free specification, and any solder with the above alloy com

-

position may be used.
