MAINTENANCE
Head Cleaning
After ten hours of usage, tape coating material or dust may adhere to the heads,

DEMAGNETIZATION
After 20-30 hours of use, enough residual magnetism will
build up on the heads to cause poor high frequency
reproduction. At this time you should use a commercially
available cassette tape-type head demagnetizer.
When cleaning the tape path or demagnetizing the
heads, be sure to follow carefully the instructions of the
concerning materials such as cleaning uid or head
demagnetizer.
