6. DUAL BACKUP MEMORY
This product has a Dual Backup Memory function. The
conventional Backup functions to memorize, in the EEP-
ROM (IC12) in the circuit, a current setting of the moment
the main power is turned off so that it can be restored when
it is turned ON again. Meanwhile, the DUAL BACKUP
MEMORY is capable of memorizing any arbitrary setting
that is configured while the product is in operation so as to
restore it at any time.
When servicing units returned from end-users for repairs,
