The Iop value labeled on the optical pick-up can be stored in the non-volatile memory. By storing the value, it will eliminate the need to look
at the value on the label of the optical pick-up. When replacing the optical pick-up or non-volatile memory (IC195 of BD board), store the Iop
value on the optical pick-up according to the following procedure.
Record Precedure:
1. Press the   ?/1

When performing adjustments, use the specified values for adjustments.
• 0.93 mW power
Specified value : 0.85 to 0.91 mW (KMS-260B)
0.80 to 0.96 mW (KMS-260E)
• 7.25 mW power
Specified value : 6.8 to 7.2 mW (KMS-260B)
7.0 to 7.5 mW (KMS-260E)
• Iop (at 7.25mW)
Labeled on the optical pick-up
Iop value 
± 10mA
• Unsatisfactory if displayed as “NG : XXXX”NG
(XXXX are arbitrary numbers)
• Unsatisfactory if displayed as “T=@@ (##) [NG]”
NG
(@@, ## are both arbitrary numbers)
