CAUTION:
For continued safety, replace safety critical components only with manufacturers 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.
