Cleaning the heads and peripheral components
For maintaining the best condition of the deck and for longer service life, always
keep the heads (recording / playback / erase), capstan and pinch roller clean.
To clean them, perform the following:
1.Open the cassette holder.
2.Using a cotton swab dipped in alcohol, clean the head (recording / playback /
erase), capstan and pinch roller carefully.
Demagnetizing the head
When the recording / playback head is magnetized, the sound quality will
deteriorate. In such a case, demagnetize the head using a commercially available
demagnetizer (head eraser).
Maintenance
There are precisely aligned parts around the heads, including the tape guides.
When cleaning, pay special attention so as not to apply shock to them.
