Opening the clock or movement voids the warranty. 

 

CAN I WIRE A CONTROL TIMING CIRCUIT TO THE LA CROSSE TECHNOLOGY

®

 

ATOMIC CLOCK?

WHY DO THE HANDS SPIN ONCE OR TWICE EVERYDAY? 

 

 

When the hands spin about the same time every day the clock is auto-correcting 

the time. The hour hand should not spin more than twice around the clock. 

 

Hands may spin if the battery is underpowered or over powered.  

 

Use only Alkaline batteries in the clock. 

 

 

HANDS SPIN NON-STOP 

 

 

This is indicative of a low or overpowered battery (number 1 warranty issue). 

 

Replace battery and perform restart procedure. Allow 5 days to catch the WWVB 

signal 

 

If constant spinning continues, the movement may need replacement. 

 

HANDS JUMPS OR JERKS AROUND THE DIAL 

 

 

This is indicative of a low or overpowered battery (number 1 warranty issue). 

 

Replace battery and perform the 

restart procedure

. Allow up to 5 days to receive a 

signal. 

 

If the hands continue to jump, the movement may need replacement. 

 

HANDS STUCK AT CERTAIN TIME 

 

 

This is indicative of a low or overpowered battery (number 1 warranty issue). 

 

Replace battery and perform restart procedure. Allow up to 5 days to receive a signal. 

 

Check to see if the hands may be bent. 

 

Movement may need replacement. 

 

HANDS ARE LOOSE. 

 

 

If under warranty, the clock must be sent in for repair or the movement needs to be 

replaced.
