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.

RX, TX Bandpass Filters The RX and TX bandpass filters provide two functions. The first is to effectively pass the correct frequencies to the RX and TX sections of the RF module. It is important especially for the RX section that these filters have a low insertion loss in order to ensure a low front end noise figure. These filters are also designed to provide >25dB rejection for the opposite band. This means that the transmit carrier will be attenuated by at least 25dB before entering the receive section of the phone. A plot of the low band filter is shown below.
