Digital clock has distorted or frozen display 

 

Explanation: On a brand new digital clock, check for thin plastic film of printed 

scratch guard that may be on the screen of the digital clock. This thin piece of 

plastic has printed numbers for store displays. When the batteries are installed, the 

“real” numbers show behind the printed scratch guard and create distortion. 

 

With all power removed, the digital clock should be blank.  

 

If numbers still appear, please check for scratch guard. 

 

Power: 

 

Check that the batteries are installed correctly.

 Digital clock drains batteries quickly 

 

 

Test a new set of alkaline batteries. Write down the date of installation and the 

voltage of the batteries. 

 

When the batteries fail, please note the date and voltage again. This is helpful in 

determining the problem.
