FT-2700RH_serv维修手册含电器原理图

FT-2700RH TECHNICAL SUPPLEMENTThis manual is intended to serve as a supplement to the FT-2700RH OperatingManual.Detailed information regarding functions,specifications,optionsand operation has been provided in the Operating Manual,and is not re-printed herein.Therefore,this supplement is not intended to serve as anindependent reference,but to be used in conjunction with the informationprovided in the Operating Manual.Because of the compactness and complexity of the double-sided glass-epoxycircuit boards used in the FT-2700RH,four layout diagrams are provided foreach board.Each side of the board is identified by the type of the majorityof components installed on that side.In most cases one side has only chipcomponents,and the other has either a mixture of both chip and lead compo-nents (trimmers,coils,electrolytic capacitors,packaged ICs,etc.),orlead components only.The two "obverse"views depict the board as it isseen when viewed directly with the eye,while the two "reverse"views depictthe unseen side of the board as it would appear if one were to peer throughthe board from the other side without seeing the components and tracks onthe near side.While we believe the technical information in this manual is correct,Yaesu assumes no liability for damage that may occur as a result oftypographical or other errors that may be present.Your cooperation inpointing out any inconsistencies in the technical information would beappreciated.Yaesu Musen reserves the right to make changes in the circuitry of thistransceiver,in the interest of technological improvement,without notifi-cation of the owners.Downloaded byl▣▣Amateur Radio Directory-1
