DEMAGNETIZING THE HEADS
Either prolonged use, or an accidental con-
tact with a piece of magnetized steel (screw-
driver, scissors, etc.) will magnetize the
heads causing an increase in tape noise. In
such an event, demagnetize the heads using
a commercially available head demagnetizer.
CLEANING THE CASING
Clean the casing with a soft cloth slightly
moistened with water or a mild detergent
solution. Do not use solvents such as alco-
hol, benzine, or thinner as they may mar the
finish of the casing.
