TDK Head Demagnetizer HD-30

[@davidtube9895]

TIPS IN USE • Set your machines volume control knob all the way to zero or turn the power source off. • Don't use the demagnetizer with headphones on. •If this is used in the wrong way and your machine is still operated, it could effect your amplifier and speaker by a strong signal output which is triggered by the demagnetizer although it lasts short time. 4TDK Made in Japan

So how does this work? The electronics in the cassette get power from the head itself?

If you pause at 0:27 up left & up right in both sides you can clearly see coin shaped batteries unless i'm wrong ? but i don't think i'm !!
