Before installing a digital certicate on the projector, you are required to set [DATE,
TIME PRESET] for checking the expiration date of the digital certicate.
Set the current date and time (i.e., local time), and the time zone.
Important:
• If setting of [DATE, TIME PRESET] is not correct, a message “authentication error” will be
displayed because of failure of checking the expiration date of the digital certicate when
you install a digital certicate. (→

• The projector has a built-in clock. The clock will keep working for about weeks after the
main power is turned off. If the main power is off for weeks or more, the built-in clock
will cease. If the built-in clock ceases, set the date and time, and the time zone again.
The built-in clock will not cease while in the standby mode.
