Hey Guys,

I've bought a TDK HD-01 Head Demagnitizer which appears to be working correctly, I replaced the battery and now the red led lights up when pressing play with the tape in the cassette deck.

It didn't come with any instructions, so can anyone tell me the correct way to use it or email me the instructions to gregorybotha@me.com.

Thanks,

Greg

You are using it correctly.
When you hit play and the red light comes on leave it for only 1 SECOND,then press stop!
Failure to do this may damage your heads. Beware!

Dinosaur is absolutely correct. I have a similar cassette demagnetizer and the instructions advise only 1 second of use.
