CAUTION: For continued safety, replace safety critical components only with man-
ufacturer's recommended parts (refer to parts list).
indicates safety critical com-
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 voltmeter with no signal input. The mea-
surement value may vary depending on the measuring
instruments used or on the product.
