Extending Password Duration Time
IMPORTANT: This operation is applicable only to those
machines that display the basic screen based
upon password input.
By using the password duration screen, password duration
time can be set. When you restarting the machine, a password
need not be input within that timeframe.
1. When turn the key switch to the OFF position, the moni-
tor unit displays the password duration screen for ten
seconds.
2. While the password duration displays is still displayed,
push a relevant key, and password duration time is set.
Duration time assigned to each key is as follows:
key 1: 0 minute
key 2: 30 minutes
key 3: 60 minutes
key 4: 90 minutes
key 5: 120 minutes
NOTE: If password duration time is not set explicitly, 0 minute
on duration time is assumed.
3. If turning the key switch to the ON position within pass-
word duration time, the monitor unit displays the basic
screen after the starting screen.
