Last week I bought a second hand Panasonic AG-7500 SVHS Hi-Fi Video Cassette Recorder. It is a professional machine with many video and audio options. I feared it would be a huge quest to find a manual. I was delighted when I found owner-manuals.com. After payment I received the file to download the next day already. The quality is great. I am very happy. Thanks!
The owner's manual/operating instructions that I purchased was the original factory document and it was in at least three and maybe more languages. I no longer have it because I sold the tape recorder and included the owner's manual/operating instructions and a service/repair manual that I bought on ebay for the new owner.
Manual was destroyed and this purchase made it possible to recover my manual . It was easy to down load and smooth to use thanks .

Power of the received RF signal
In display panel , the power of the received RF signal in (µV) and the level control of the AF signal � i.e. the modulation of the RF signal (in %) are shown. Both displays have an overmodulation display. If the signal is too high, the text �PEAK� lights up briefly. Short overmodulation is not critical. Where longer overmodulation occurs, the modulation of the corresponding transmitter must be reduced. For the AF signal, �peak hold� is also shown, which means that short peaks remain visible for some time.

Squelch (Muting)
The EM 3031/3032 receiver is equipped with an adjustable squelch control which eliminates annoying noise when the transmitters are switched on and off. It also suppresses sudden noise when a transmitter leaves the reception area and there is no longer sufficient transmitter power received by the receiver. The squelch is adjusted on the rear of the receiver with control (�MUTING�). The adjustment range is between 0 and about 100 µV. When the squelch is active, the text �MUTE� is shown in display panel .
AF squelch
The squelch also switches on when the selected radio channel is occupied by a wideband interference signal such as that generated by lighting control systems. This prevents an interfering signal from hindering reception even when the interfering signal has a high RF level. When control (�MUTING�) is set to position �0�, the AF squelch is also switched off.
