CONTAX - Contax RTS Service

Comprehensive service manual for the CONTAX RTS camera, issued by Yashica Co., Ltd. This workshop reference provides detailed assembly and component information across fourteen pages of exploded-view diagrams paired with complete parts lists. The systematic illustrations break down all major subsystems: focal plane shutter mechanism and curtain operation, mirror assembly, film advance and sprocket drive systems, flash synchronization circuits, optical components, and viewfinder with exposure control assemblies. Each diagram includes a corresponding parts table that identifies component numbers, functional descriptions, and required quantities for assembly and reassembly work. A dedicated technical section examines the focal plane shutter design in depth, covering primary and secondary curtain traverse characteristics and performance curves specific to the CONTAX RTS. Practical troubleshooting and repair guidance addresses common operational failures—fast shutter speeds, shutter jamming or remaining open, failure to fire, and premature curtain release—with identified root causes and step-by-step correction procedures for each condition. Electrical schematics and voltage checkpoint locations are included for exposure control circuit calibration and verification. Additional sections detail shutter curtain assembly methodology, spring tension winding procedures, and precision adjustment techniques essential for maintaining camera performance to specification. This manual is an indispensable reference for service technicians and experienced camera enthusiasts undertaking detailed repairs, restoration, and maintenance of CONTAX RTS bodies.
