Not a product catalog - Pioneer published this as a consumer education booklet in 1983, titled “Deck 200%活用法” (How to get 200% out of your deck). Three parts cover the basics (bias, Dolby B/C noise reduction, recording EQ at 70 us/120 us), recording from different sources (vinyl, CD, FM, tape types), and advanced techniques including DJ methods like Cross-Fade, Fade-In/Out and Snake-In/Out. The PIONEER CT-90R auto-reverse deck features on the cover and in a dedicated spread. Distributed free of charge, with a tear-out question card addressed to the Pioneer Deck Clinic Center in Tokyo.
