ty critical components. For continued protection against risk of
fi
re, 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 with no signal input. The measurement value may vary depend-
ing on the measuring instruments used or on the product.
