CAUTION: For continued safety, replace safety criti-
cal components only with manufacturer's recommend-
ed 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 sup-
ply circuit) before the appliance is returned to the cus-
tomer.
The DC voltage is an actual reading measured with a
high impedance type voltmeter. The measurement
value may vary depending on the measuring instru-
ments used or on the product. Refer to the voltage
during PLAY unless otherwise specified; The value
shown in (
) is the voltage measured at the moment
of STOP.
