NOTES:
1) Clean heads prior to head adjustment.
2) Be careful not to use a magnetized driver or other
magnetized tools in the vicinity of the heads.
3) Use only new tape as level variation is likely to occur
when using old tape.
4) Demagnetized heads with head demagnetizer before
and after head adjustment.
5) As perfect head adjustments are vital to tape deck or
recorder performance, be sure that these adjustments
are carried out properly.
