This place is amazing. Got our manual in a few hours. Print quality is excellent. Even the manufacturer didn't have this manual. The price was excellent. How many more stars can I give them? More than satisfied.
I'm so glad I was able to find a site to download my missing manuals. Very reasonable prices and they kept me informed about the process and I had my manual within less than a day. The only thing I wish was an option is a 100% English version with no spanish or anything. But overall great site.
The manual is complete with excellent quality! One suggestion, show number of pages and weather it is multi-lingual. The AD 600 Manuel is about 76 pages and over half is non English. This results in a larger print job than usually needed. Having this information, one could select the desired pages for printing.
I've been looking for a copy of the original user/owner manual. Just what the doctor ordered, thank you.

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.

This filter is used for the RX filter in the handset or the TX filter in the base. The high band filter characteristic is shown below. This filter is used for the handset TX filter and base RX filter.
