GX204KEF2/KHF2 GX204LEF2/REF2 GX204SEF2SERVICE MANUALSUBARU GENUINEThe knobs with numbers larger than 700 on exploded view are not supplied for service parts because it is difficult to apply grease. Please change to panel assy when you need repair to the knob. The 6CD mechanism has not supplied repair parts for each part (for Optical Laser pickup, motor etc). If you need repair to the 6CD mechanism please change to mechanism assy (D40-2214-15).

CAUTION : For continued safety, replace safety critical components only with manufacturers recommended parts (refer to parts list). Indicates safety critical components. To reduce the risk of electric shock, leakage-current or resistance measurements shall be carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer. DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variations between individual instruments or/and units.

CAUTION : For continued safety, replace safety critical components only with manufacturers recommended parts (refer to parts list). Indicates safety critical components. To reduce the risk of electric shock, leakage-current or resistance measurements shall be carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer. DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variations between individual instruments or/and units.
