Time

The PT-7728 has a time calibration function based on information from an NTP server or user

specified time and date. Functions such as automatic warning emails can therefore include time

and date stamp.

NOTE The PT-7728 does not have a real time clock. The user must update the Current Time and

Current Date to set the initial time for PT-7728 after each reboot, especially when there is no

NTP server on the LAN or Internet connection.
