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

vary depending on the measuring instruments used or on
the product. Refer to the voltage during PLAY with DASC
OFF(at the normal speed) unless otherwise specified; The
