When no error occurs in this unit, data “00” is written in the above
addresses (F4 to FF). when first error occurs in the unit, the data
corresponding to the error is written in the first emergency ad-
dress (F4 to F7). In the same way, when the second error occurs,
the data corresponding to the error is written in the second emer-
gency address (F8 to FB).
Finally, when the last error occurs, the data corresponding to the
error is written in the last emergency address (FC to FF).
Note: After completing adjustments, be sure to initialize the data
of addresses F4 to FF to “00”.
