* Remove the cassette housing control assembly.
« Make a short-circuit between TP5005 and TP5006, both
located at the left on your side on the main PWB. Now turn
on the power.
« Setting
1. Seta torque gauge to zero on the scale. Place it on the supply
reel disk.
2. Switch from the FF mode to the STOP mode.
3. Disconnect the AC power plug.
¢ Checking
1. Rotate the torque gauge (approx. one revolution per 2 sec-
onds) in the clockwise {CW) direction and counterclockwise
(CCW) direction of the supply brake so that the reel disk and
the indicator of the torque gauge rotate at an equal rate.
Check that the values are within the range of CW direction =
10 ~32mN-m (100~330gf-cm), CCW direction =5.9~9.8mN-m
(60 ~100gf-cm), and that the brake torque in the CW diretion
is at least twice as high as that in the CCW direction.
