Reassemble the cassette
housing assembly to the
mechanism as the cancel lever
is moved in the direction of the
arrow.
Note 1c:
When reassembling the cas-
sette housing to the mecha-
nism, make sure that there is
no deformation in the frame or
no damage to the switches,
etc.
Note 1d:
After reassembling the compo-
nent parts, check the mecha-
nism operation in the PLAY
mode.
For details of checking method,

Note 2a:
When removing the reel disk assembly, be careful not to break
the brake pad which applies lateral pressure to the reel disk.
Note 2b:
Be careful not to make a mistake in installing the reel disk.
The SUP reel disk and TU reel disk can be distinguished from
each other by the appearance as shown below.
Note 2c:
When removing the reel cover assembly, pay heed to the guide
arm assembly. For, the guide arm assembly is just inserted
into the slide deck assembly from the upside and it is apt to
come off after the reel cover assembly is removed.
Note 2d:
When fitting the reel cover assembly to the set, carefully tighten
the screw with the specified tightening torque of 0.069N·m
(0.7kgf·cm).
