Function 14: System clock

Function 141: Set time/date

1.Enter a new time in a twelve-hour format.

Example: Enter 1 2 3 3 for 12:33, or 3 1 5 for 3:15 (note that you need no leading zero for the time).

2.Select AM or PM by pressing a scroll key (either  or ).

3.Enter a new date in an eight-digitformat, including leading zeroes.

Example: Enter 0 7 0 4 2 0 0 6 for July 4, 2006 (note that leading zeroes are required here, unlike in Step 1).

4.Press # to finish the entry.

Note: A built-in battery maintains the correct time and date, even in the event of a power loss.

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)..
