This checks the photo sen-
sors which detect the refer-
ence angles for training
and tilting operations.
This checks the transducer
training operation. The four
digit figures show the num-
ber of pulses used to train
the transducer by 180.
If training is abnormal, NG
(No Good) count increases
by one.
This checks the transducer
tilting operation. If the num-
ber of pulses used to tilt the
transducer is abnormal, NG
count increases by one.
