[7] MAINTENANCE AND DETAILS OF EACH SECTION
• Self print of set values
Use of SIM 22-6 allows to print the set values and the jam his-
tory of the machine.
These values must be printed before execution of maintenance
or disassembly procedures.
• When assembling, check that the flat cable and the harness
connectors are securely connected.
• When connecting the flat cable, be careful not to break the pins.
When installing the PWB unit and the memory module, use a
Ground Strap to prevent damage caused by electrical dis-
charge.
