1 . W i r e c o n n e c t i o n for m o t o r s a n d leaf s w i t c h e s is as s h o w n
in Fig. M 4 2 .
1) C o n n e c t the black, y e l l o w , red a n d orange w i r e s f r o m
t h e 4-P s o c k e t t o BLK, YEL, RED a n d ORG w i r e s ,
respectively.
2) C o n n e c t the blue w i r e of the 3-P s o c k e t t o the blue w i r e
of the start limit d e t e c t i o n
l o a d i n g m o t o r PCB, the b r o w n w i r e to the b r o w n w i r e of
the closed tray d e t e c t i o n leaf s w i t c h t h r o u g h the s a m e
PCB, a n d the gray w i r e t o the gray w i r e of the o p e n e d
tray d e t e c t i o n leaf s w i t c h directly.
3) C o n n e c t the red a n d black w i r e s of the disc m o t o r t o the
D.RED a n d D.BLK w i r e s in the loading m o t o r PCB,
respectively.
Note: When wire connection is made as instructed in paragraph 1)
and 2 ) , the red wire of the disc motor is connected with the
black wire of the 4-P socket, and the black wire with the red
wire.
2 . W i r i n g is p e r f o r m e d as s h o w n in Figs. M 4 3 - M 4 6 .
1) Perform w i r i n g of the m o t o r PCB exactly as s h o w n in
Fig. M 4 3 . In this c a s e , note the f o l l o w i n g three p o i n t s :
a) Slacken the w i r e i n d i c a t e d by a r r o w [ A ] .
b) Slightly b e n d the section i n d i c a t e d by a r r o w [B] in
t h e d i r e c t i o n in w h i c h the w i r e is p u t in.
c) Bring the locking part of t h e w i r e b a n d u p w a r d i n ­
d i c a t e d by a r r o w [ C ] , as s h o w n .
2) Perform w i r e b u n d l i n g in t h e rear of the m a i n chassis
exactly as s h o w n in Fig. M 4 4 . In this c a s e , the n u m b e r
of w i r e s to be b u n d l e d in the l o c k i n g part is 8 , a n d t h a t
in t h e head amplifier PCB is 9.
3) In w i r i n g the p i c k u p s e c t i o n , solder t h e r e d , black a n d
y e l l o w w i r e s exactly as s h o w n in Fig. 4 5 , a n d secure
these three w i r e s by a w i r e c l a m p .
4) In w i r i n g the head amplifier PCB a s s ' y , solder the r e d ,
black a n d y e l l o w w i r e s exactly as s h o w n in Fig. M 4 6 .
In a d d i t i o n , m a k e sure t h a t no c o n t a c t o c c u r s b e t w e e n
any t w o of the transistors, coils a n d c a p a c i t o r s s h o w n
in Fig. M 4 6 .
