Atomic clock is dim
Explanation: Most atomic clocks have a dark background. Place the atomic clock at eye level, to determine
if it is dim. Atomic clocks that sit in the sunlight can develop a cloudy film over time.

Atomic clock has distorted or frozen display
Explanation: On a brand new atomic clock, check for thin plastic film of printed scratch guard that may be
on the screen of the atomic 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.
