Very clear scan, I recommend it. Definitely a must have for any 3362 owner.
Alpine could have written a slightly more complete manual, though. It's already pretty huge, but the unit has so many functions, I feel some more explanation would have been better.
Yamaha's manual of their comparable YDSP-1 is a little better in my opinion.
Correct manual received and of good quality but the contents of the file for the Service Manual for the same monitor is for a 20" TV not the RGB Monitor.
