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

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 Savings Time
This function, when enabled, causes the real-time clock to adjust itself automatically for
Daylight Savings 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.
