HEAD CLEANING
The most frequent cause of failure to record in one or both
channels, or of weak, distorted sound, is dirty tape heads and
capstan. So, be sure to clean the heads, capstan, pinch roller
and tape guides as often as possible using a "Q" tip dipped
in ordinary rubbing alcohol or commercial liquid tape head
cleaner. Thoroughly wipe the surface of the heads, capstan,
roller and tape guide.
HEAD DEMAGNETIZING
The tape heads, capstan and tape guides gradually become
magnetized with use, which will eventually affect the sound
quality of your tapes. Demagnetizing should follow cleaning,
but need not take place as often as cleaning, once after every
20 to 30 hours Of use Should suffice,
A demagnetizer may be purchased at a moderate cost from
any dealer carrying tape recording accessories. Follow the
instruction supplied with the demagnetizer.
Caution: Be sure to turn off the unit before you attempt
demagnetizing.
