CAUTION: For continued safety, replace safety critical
components only with manufacturer's recommended parts
(refer to parts list).     indicates safety critical components.
For continued protection against risk of fire, replace only
with same type and rating fuse(s). 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.

The DC voltage is an actual reading measured with a high
impedance type voltmeter. The measurement value may
vary depending on the measuring instruments used or on
the product. Refer to the voltage during RECORDABLE MD
PLAY unless otherwise specified; 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.
