SERVICE MANUAL 19" COLOR TELEVISION EWT19S2 IMPORTANT SAFETY NOTICE Proper service and repair is important to the safe, reliable operation of all Funai Equipment. The service procedures recommended by Funai and de- scribed in this service manual are effective methods of performing service operations. Some of these service special tools should be used when and as recommended. It is important to note that this service manual contains various CAUTIONS and NOTICES which should be carefully read in order to minimize the risk of personal injury to service personnel. The possibility exists that improper service methods may damage the equipment. It also is important to under- stand that these CAUTIONS and NOTICES ARE NOT EXHAUSTIVE. Funai could not possibly know, evaluate and advice the service trade of all con- ceivable ways in which service might be done or of the possible hazardous consequences of each way. Consequently, Funai has not undertaken any such broad evaluation. Accordingly, a servicer who uses a service proce- dure or tool which is not recommended by Funai must first use all precau- tions thoroughly so that neither his safety nor the safe operation of the equipment will be jeopardized by the service method selected.
