ufacturer's recommended parts (refer to parts list).
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 appliance is returned to the customer.
The DC voltage is an actual reading measured with a high impedance type volt-
meter with no signal input. The measurement value may vary depending on the
measuring instruments used or on the product.
