CAUTION: For continued safety, replace safety critical components only with
S.BUSY
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
J6 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
P2 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 measurement value may vary depending on the measuring instruments
used or on the product.
