Handling Precautions
• Before setting the passwords 1A, 2A, 1B and 2B, determine two
hexadecimal values to be used as passwords and take a
memorandum of these passwords to record them.
• When other values are set for passwords 1B and 2B after the values
to be used as passwords have been set for passwords 1A and 2A,
the passwords 1A and 2A cannot be displayed and the key lock
cannot be changed.
This status is called “password lock status”.
• The settings, which cannot be changed by the key lock, cannot be
displayed in the password lock mode.
