AutoTime&Date
You can program the Automatic Time&Date feature to enable
the Norstar system to automatically update the time and date
after a power failure.
Whenever the clock is out of sync by more than two minutes,
as a result of a power failure or a loss of power, the first
incoming call updates the clock automatically after two rings.
Note: CLASS trunks are required for this feature to work.
Consult your customer service representative to
determine if you have CLASS trunks.
This feature also allows automatic changing between North
American daylight savings and standard time.
The Automatic Time and Date feature automatically overrides
any manually-programmed changes to the time and date.
Note: The year is not included with the time and date
information and must be programmed manually if the
current year differs from the network time.
Tip -
The time falls back one hour on the last Sunday of
October at 2:00 a.m., and advances one hour on the first
Sunday of April at 2:00 a.m. This function should only be
programmed by your installer.
New extended DST rules begin in March 2007. Daylight
Savings Time is extended by four weeks from the second
Sunday of March to end on the first Sunday of November.
In areas where daylight savings time does not apply, (for
example, Saskatchewan), make sure this setting is changed to
None.
