8-1. Mechanical Adjustment
8-1-4. REV Back Tension Adjustment
Note
When the T-tension regulator band assembly or the T reel table assembly is
replaced, or when the T tension regulator operating position adjustment is per-
formed, be sure to perform the REV back tension adjustment.
Preparations
Remove the front lid and the outside panel assembly. (Refer to Section 1-4.)
n
This adjustment is recommended to be performed with the cassette compartment
installed.
If the cassette compartment is not installed, the photo interrupter (cassette compart-
ment lock switch) on the MDC-13 board must be covered by a piece of black paper
to interrupt the incoming light to establish the cassette-lock state. At the same time,
place a weight on top of cassette tape so that the cassette tape will not be raised out
of position for this adjustment.
For the cassette compartment lock switch, refer to "7-1-3. Threading-End State/
Unthreading-End State".
