block error rate
If error rate is OK,
locks a root of
tangential and radial
adjustment screws with
the Screw tight.
Screw tight: GYL1001
Turn the POWER OFF in
case of NG once, and

•
Unfasten the radial adjustment screw
by 90 degrees step till ERROR RATE
becomes around "1E-3" again .
•
Record the number of rotation (N1).
(memorizing how much the screw was rotated.)
•
Fasten the radial adjustment screw
till the number of rotation becomes
harf of N1.
