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.

Received downlink in less then 8 hours, Item was in good copy condition, and told me how to program the clock timer. The price was very resonable, and the process was very automated and was GREAT to work with.

I was very pleased with the manual I got for my amateur (ham) radio. Without it I could not figure out how to input and/or change the P/L setting on my radio. It drove me nuts as the radio was essentially useless. That all changed when my manual came. Then it took only minutes and I was done. Now my radio works fine. This is an exceptionally good resource as it's a very easy and user friendly download. Thank you very much! Dziękujemy za!

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.
