operation again.
It is possible to preset 6 AM (MW) stations and 6 FM

AUTOMATIC SWITCHING OF MONAURAL/STEREO RECEPTION

or are surrounded by hills), the radio is automatically switched from stereo to monaural to reduce the interference.
When the stereo broadcast becomes stronger, it automatically switches back to stereo broadcasting.
