Operation/Procedure
1) Enter the number corresponding to the memory to be checked with
10-key.
2) Press [START] key.
In the case of All, all memories are checked only once.
The error address or the data line is displayed individually.
When "repeat" is selected, the operation is repeated until the result is
"NG" or [CUSTOMSETTING" is pressed.
