Missing Segments

Missing segments are often the result of overpowered or underpowered batteries.

1.  Please remove all power from the display (and sensor if you have one) for 15 minutes.
2.  With the batteries removed, press any button 20 times to clear all electricity from the unit. Please do this even if the screen is blank.
3.  After 15 minutes install fresh batteries (into the sensor first, if you have a sensor) into the display.
4.  Wait at least 15 minutes before pressing buttons.
5.  Set the time and the date, then see if you still have missing segments.
