Thank you for having the manual I needed for an older model Aiwa stero I had found on Ebay --- I wanted the Aiwa because I had tapes and cd's but I did not have a manual as to how to operate the system... I found what I needed and it has enabled me to set the system up for my enjoyment.
I wished detailed information of the JBL S310 and here I found it! Very happy with the service from this site!

Power of the received RF signal
In display panel , the power of the received RF signal in (ÂµV) and the level control of the AF signal â€“ 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 â€śPEAKâ€ś 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, â€śpeak holdâ€ť is also shown, which means that short peaks remain visible for some time.
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 (â€śMUTINGâ€ś). The adjustment range is between 0 and about 100 ÂµV. When the squelch is active, the text â€śMUTEâ€ś is shown in display panel .
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 (â€śMUTINGâ€ś) is set to position â€ś0â€ś, the AF squelch is also switched off.
