CLEANING
If excess oxide accumulates on the surface of tape path components,
normal operation and characteristics cannot be expected. Periodic
cleaning should be done with proper cleaning materials. Refer to
Operating Instructions.
DEMAGNETIZATION
Metal parts in contact with the tape will become magnetized after
long periods of use(except erase head). Magnetization of record/
playback heads causes noise in recording and reproduction and heads
should be demagnetized at every 50 hours of use, and before any
important recording is done. Refer to Operating Instructions.
