components. For continued protection against risk of
IC3 : TC7S08FU
IC4 : TC7WU04FU fire, replace only with same type and rating fuse(s). To
IC5 : TC74ACT540FS
reduce the risk of electric shock, leakage-current or
IC6 : X24C01AS-2.7
IC7 : HM51W4400BTT-7 resistance measurements shall be carried out (exposed
IC8 : BH6511FS
parts are acceptably insulated from the supply circuit)
IC10 : L88MS33T
IC11 : AK4520 before the appliance is returned to the customer.
Q1 : FMW1

Q4,5 : DTC114YUA
The DC voltage is an actual reading measured with a
Q6 : 2SA1576A(R,S)
Q7 : 2SB798-DL high impedance type voltmeter. The measurement value
Q8 : 2SJ278
may vary depending on the measuring instruments used
Q9 : 2SK1764
Q10 : DTC114EUA or on the product. Refer to the voltage during
RECORDABLE MD PLAY unless otherwise specified;
D1,2 : F1J6TP
D101 : MA101 The value shown in ( ) is the voltage measured at the
moment of STOP. The voltage followed by (REC) refers
to the value during MD RECORDING.
