CAUTION: For continued safety, replace
safety critical components only with manu-
facturer's recommended parts (refer to
parts list).
indicates safety critical com-
ponents. 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 resis-
tance measurements shall be carried out
(exposed parts are acceptably insulated
from the supply circuit) before the appli-
ance is returned to the customer.
The DC voltage is an actual reading mea-
sured with a high impedance type volt-
meter. The measurement value may vary
depending on the measuring instruments
used or on the product. Refer to the volt-
age during PLAY with DASC OFF (at the
normal speed) unless otherwise specified;
The value shown in (
) is the voltage
measured at the moment of STOP.
