Switching ON the built-in AM demodulator, the volume can be adjusted with 
the rotating knob, and the level is shown by the black bar on the screen. 
 
The demodulated signals can be heard with headphones or earphones 
connected to the front panel of the PMM 9010, or amplified and/or recorded 
by any suitable device. 
 
An FM demodulator – or other demodulators - is not available for the time 
being in the frequency band covered by the PMM 9030.
