Stereo reception
The stereo indicator symbol M m w i
lights up if a stereo program is
received.
The radio is equipped with an
autom atic stereo/m ono sw itch that
electronically switches to mono fo r
clear reception if a weak signal is
received. A special circu it provides
fo r a smooth change-over rather than
a hard sudden sw itching, thereby
reducing noise and interference.
The stereo indicator will remain lit
even if the receiver has changed to
the mono mode and will turn off at an
antenna signal considered insufficient
to provide acceptable reception qual­
ity.
