Well, as suspected, that was not original. 
See, 16, being the predecessor of 116 series, had the same type switch, usually mount on a side of the cabinet. That would turn interstation noise suppression On/Off and worked through the AVC circuit. Tthere was also a pot in the back, that would adjust the level of this function.
What it did was, when you tune, you listen to all kind of noise, so in the absence of a usable signal the circuit would suppess the noise while tfuning between stations, so the radio would be quiet until having acquired a station.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
