CD MECHANISM

CAUTION:For continued safety, replace safety critical components only
with manufacturer’s 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.
