Power cord
• Power cord (5-volt) as primary power source. A CR2032 battery may be added to back
up time and date.
Note: Backup battery will not run the clock display.
• When operating with the power cord, the backlight can be on continually.
Clock Factory Restart
Explanation: The factory restart returns the clock to an “out-of-the-box” default state and
often resolves an issue.
Factory Restart:
1. Remove all power (batteries and power cord) from the clock.
2. Press one of the buttons on the clock at least 20 times to clear all memory.
3. Verify that the clock is blank before proceeding (there may be lines painted on the
screen that will show when there is no power).
4. Leave without power for 15 minutes (very important).
