The "I" (Interchangeability) column indicates whether a modified part can be installed in pre-modification machine. If a "Y" is listed under the "I" column, a part under "AFTER MODI. P/NO. " column can be installed in pre-modification machine and the machine functions properly. If a "S" is listed, there is a new part which is used with the modified part as a set. The set can be installed in pre-modification machine and the machine functions properly. If a "N" is listed, the modified part cannot be installed in pre-modification machine. Even though the modified part could be installed in the machine physically, it would not function properly. The "SE/No. " column indicates a serial No. and the following 5 meanings. 1. "Blank" shows that there is no modification.( A revised version will be followed as soon as a serial No. is confirmed.) 2. "" shows that a modification has been done.( See the above section for the details.) 3. "N/A" shows that a modification has been done.(The serial No. can not be confirmed.) 4. "AFTER" shows parts which are not used in the production line but used only as the spare parts. 5. "DISCON" shows that the model has been discontinued for the production. The "SFIX" column indicates the area codes ( the last three numbers on the item code). The area code "000" means the part can be used in all areas.
