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 dur ing PLAY
unless otherwise specified; The value
shown in ( ) is the voltage measured at
the moment of STOP.
