CAUTION: For continued safety, replace safety critical
components only with manufacturer's recommended parts
(refer to parts list).
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 insulated
from the supply circuit) before the appliance is returned to
the customer.
The DC voltage is an actual reading measured with a high
C503,506,
SW502 M501
507 impedance type voltmeter with no signal input. The
NO NO NO
measurement value may vary depending on the measuring
YES YES YES
instruments used or on the product.
