CAUTION:
For continued safety, replace safety critical components only with manufacturer's recom-
mended 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 insu-
lated 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.
