5. Since the following parts are exothermic, make sure that
such parts will not come into contact with any electrolytic
capacitor, wire and other parts.
ICA05,ICA06,IC502,1C701 ,D952,Q808,QF02,R867,R857 ,
RF38 and heat sink are exothermic parts.
6. Any wire, etc. should be clamped or bonded as indicated in
the above diagram so that such wire will not be positioned

the figure so that the wire do not touch to live parts mowing
part, hot part, or sharp edges.
8. By using the special tool , attach the power cord bushing to
the position where “4N — 4” is marked.
9.Set and firmly fix the fuses F951,F952 and F953 respectively
to T400mA, T6.3AandT6.3mA afterconfirmingthe respectively
positions.
