6.8.2Change Date & Time/Automatic Daylight Saving Time

The Liqui-tect panel has a built-in, real-time clock that is backed up by an encapsulated lithium bat- tery and set up to adjust automatically for daylight saving time twice a year. The Setup System Info menu allows you to change the date or time or automatic adjustment at any time.

To change the daylight saving time setting, date or time:

• From the Setup System Info Menu, use the arrows ↑↓ to choose Change Date & Time, then press Enter .

• To change the daylight saving time setting:

• To the right of Daylight Svg Time? use the arrows ↑↓ to choose Y (Yes - automatically adjust for daylight saving time) or N (No), then press Enter .

The format of the date and time is DD-MMM-YY HR:MM:SS. To change the date or time:

Press Enter to advance to the next character position you want to change.
