Do not throw away the transparent sheet covering the main board. This sheet protects the harness from being scratched by the hooks on the inside of the bottom cover. After replacing the main board, re-attach the sheet. If the adhesive is weak, reinforce with double-sided tape.
Before replacing the main board, print the Configuration page by pressing the Power button 3 times rapidly.
The EEPROM cannot be removed. Before replacing the main board, remember the machine’s "PNP ID", "Destination Code", and "Serial No.". After replacing the main board, enter them manually by using CE Tools. For details, refer to Using CE Tools
