Select the box to the left of “Change Date and Time” below the clock to display all
the RTC parameters as shown below.
6.
Select the “Sync To System Time” button and the RTC values will sync with the
RTC on the computer and continue running from that point, keeping the correct
time and date. The RTC module chip contains a battery to retain the RTC
parameters even when power is turned off to the C445. The memory on-board the
RTC module is non-volatile memory and does not use the battery to retain its
contents. This will be discussed further below.
Note:
Time management in the real time clock module starts using the default values
(01/01/2000 00:00:00). If a real time clock board is not present then the date and
time will reset to this value every time the C445 powers up. If a RTC module is
installed, the time and date will increment continually.
