Having bought a pre-owned Sony FM stereo tuner through eBay, it came without any manuals. It soon became clear that to get the best from this excellent tuner I needed a decent manual because much of the operation was not intuitive to a newboy to hi fi like me. I managed to download the official Sony multi-lingual manual from Owner-Manuals.com with no problem at all - a really quick and easy service. I'm very glad I did because I found out all the operations of the tuner and was then able to not only set it up quickly but also to get much more from it that poke-and-hope trialling would ever achieve. In my book $4.99 very well spent.
This manual is immaculate in it's accuracy. Everything is written very clearly and easy to understand. Written by a professional who wants to convey a clear and easy to understand message!!
Great site, I always find all the manuals I need and i can't find anywhere else. PDF for the Sony PCM 3348 is complete and scan is good quality. Thank you!
