The manual was complete and of great quality. Originally a tri-lingual file, I first received only one language. After a note to owners-manuals.com, I quickly received the remaining languages... Great service, definitely worth it.

Thank you for providing this manual and at low cost.
The Philips scope is of excellent quality, longevity and build and had a couple of faults
when it was passed to me. Having the CCT diagrams is a blessing.
I have fixed the problems and also modded the scope to my requirements.
I have built a 24v Li-Ion pack for portable use from old but good laptop batts.
it is working beautifully and I am well pleased. Keep up the good work Guys.

Awesome quality manual. You really saved my bacon with this one. Was looking for some specific information with regards to my "new" vintage VCR that didn't come with the owners manual. This site is truely a goldmine of available manuals. The quality of the scans are top notch.
Thank-you so much for this awesome manual. If you're looking for this Sony SL-HF400 owners manual, this is the one you NEED to buy. Definitely worth the money.

The manual was made available promptly. I is a clean scan of the original. I had no problem downloading it. The scan was well centered and cleanly formatted. It is as good a product as can be had without being the original document.
The problem of noise The negative effects of noise pollution have been proven by studies, and everybody will have experienced them: Nervousness Lack of concentration Irritability And these are only the most obvious effects on the human body. Noise also affects the autonomic nervous system and can lead to permanent hearing damage. There are a multitude of noise sources, and the individual very often has no influence over them. The only solution when being in a noisy place is protecting oneself against ambient noise. These noise problems are particularly prevalent in an aircraft cockpit where a pilot often has to have the communications headset so loud as to risk permanent hearing damage. With the NoiseGard® system, Sennheiser has come up with an effective solution. These operating instructions explain the NoiseGard® principle and show you how to use the NoiseGard® headset.
