CAUTION: For continued safety, replace safety
critical components only with manufacturer's
recommended 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
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. The
measurement value may vary depending on the
measuring instruments used or on the product.

CAUTION: For continued safety, replace safety critical components only with
manufacturer's recommended 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 insulated from the
supply circuit) before the appliance is returned to the customer.
