MAIN Unit

IntroductionThis manual provides the technical information necessary for ser-vicing the FT-4XR/FT-4XE and FT-4VR/FT-4VE 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.

CautionRisk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instruc-tions.

Important NoteThis 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.
