The parts should be replaced exclusively by an authorized service center.
To identify the codes of replacement parts, contact a service representative.
Once you have precisely identied the parts required, the support service will send a
written order to the manufacturer, specifying clearly the model of the device, its serial
number, the voltage and frequency of power supply, and also the code and a descrip-
tion of the parts concerned.
