Using a text editing program such as WordPad, create a new plain-text file.
On the first line of the text file, you will be typing a date and time. Select the date and time that you plan to be out at the sign (such as five or ten minutes in the future). Enter the date and military time in the following format:
20160926 14:30:00 for 2:30pm on 9/26/2016)
Optionally, on the second line of the text file you can place the timezone. Commonly used timezone values are:
America/Anchorage America/Chicago America/Denver America/Goose_Bay America/Jamaica America/Los_Angeles America/New_York America/Phoenix America/Puerto_Rico America/Regina Pacific/Honolulu
A full list of valid timezone values can be found here.
Save the text file with a name of
time.txt in the root folder of an empty USB drive.
At the time you specified above, plug the USB drive into your sign’s external USB port. This will update your sign’s clock, and your new date and time will show automatically. However, if you entered a timezone you will need to turn your sign off and back on for the new settings to take effect.
