Configuration manual for 2N IP intercoms
5.6.2 Date and Time
If you control validity of phone numbers, lock activation codes and similar by time profiles,
make sure that the intercom internaldate and time are set correctly.
Most2N IPintercom models are equipped with a back-up real-time clock to withstand up to
several days' long power outages. If not equipped with this function, the intercom loses the real
time data upon power outage (or restart). Therefore, if the intercom is powered up after a rather
long period of time (after new intercom installation, e.g.), time is set to the default value and has
to be reset. Select Use time from Internet to synchronize the intercom time with the internet
time or click Synchronize with browser to synchronize the intercom time with your current PC
time.
To maximize the accuracy and reliability, we recommend that you always enable the Use time
from Internet function. The device time error can be up to ±2 minutes per month under normal
operation conditions.

Note
The intercom does not need the current date and time values for its basic function.
However, be sure to set these values when you apply time profiles and display time of
listed events (Syslog, used cards, logs downloaded by HTTP API, etc.).
