3.2. ROM & RAM check
ROM executes the sum check, and RAM executes the matching test.
The result will be notified with the number of short sounds of the buzzer
as well as by printing the ROM & RAM check list.
If error does not occur, the buzzer does not sound.
(
As for the print format refer to the list function specification.)
