1-7-3. Tape Transport System Adjustment
The tape transport system has been precisely adjusted in
the factory, so only when some defective phenomenon
occurs such as noise observed on the screen and tape
damage, or when replacing the portion shown on the
adjustment procedures of the tape transport system,
adjustment and check are necessary.
Electrical signal output terminal required for adjustment
differs depending upon the models. Refer to the test
point location in the Electrical Adjustment Section.
