ATA CARD Check
This item checks the ATA card (QM-421P) and its interface. This check is almost
the same as the MEMORY CARD check, except for the COMMON CHECK.
The COMMON CHECK is the write/read check for common area by each sector.
This check continues until you touch the “STOP” key or “RETURN” key.
The check method is the same as the system RAM check.
If an error is detected, the QM-421P or MAIN board will be faulty.
Procedure to Start and Exit the ATA CARD Check Program
1. To select the ATA CARD Check, touch the “ATA CARD CHECK” key.
2. To display the dump list of attribute area which is in the ATA CARD, touch the
“ATTRIBUTE CHECK” key and touch the “NEXT PAGE” or “PREVIOUS
PAGE” keys, if necessary.
3. To start the common check, touch the “COMMON CHECK” key.
If the check program finds an error, it displays the address, write data and read
data as shown in the above table.
4. To stop the check temporarily, touch the “STOP” key. The “START” key name
changes to normal and the “STOP” key is highlighted.
To continue the check, touch the “START” key again.
