Function 142: Automatic time setting
1: Synchronize with CID
This function, when enabled, synchronizes the real-time clock with Caller ID (CID) messaging: call
processing compares the time of a CID message to the system real-time clock and, if the difference is
more than two minutes, resets the real-time clock to match the time (hours and minutes) of the CID
message. The system will analyze each such message (or — if it receives more than four calls with CID
information within a one-minute period — as is needed). Select
ENABLE
or
DISABLE
by pressing a scroll
key (either
or
). Choosing
ENABLE
will allow the CID data to update the time and date.
Default:
Enabled.
2: Adjust for Daylight Saving Time
This function, when enabled, causes the real-time clock to adjust itself automatically for Daylight Saving
Time (DST). Select
AUTO
or
DISABLE
for DST by pressing a scroll key (either
or
). Choosing
DISABLE
is best for those areas that don’t observe DST.
Default:
Disabled.
Note:
If this function is enabled and it causes an automatic time change, the system won’t update the real-
time clock from Caller ID messages (Function 1421,
above
) for 25 hours before and 25 hours after
the time change is due to be effective (
i.e.
, 2:00
AM
Sunday).
Function 143: Clock adjustment
This function lets the Installer or Administrator have the system automatically compensate for a clock that’s
running too fast or too slow. The clock adjustment speeds up or slows down the clock over a 30-day period by
the amount selected. If the system clock is running
slow
, select a
positive
value. If the clock is running
fast
,
select a
negative
value.
Range:
-2 to +5.5 minutes.
Default:
0.
Example:
If the clock is running two minutes fast over a month, select -2 (minus two minutes)..
