No WWVB Tower Icon 

 

  The clock has not received a WWVB time signal in the past 24 hours. 

 

Position

 the clock for better reception. 

  Hold the 

TOWER

 button to send the clock on a signal search at night. 

  Allow up to 5 nights to receive the time signal. 

 

Daylight Saving Time 

 

 

Dependent on your location, position of the clock in your home, and atmospheric 
interference, it may take up to 5 nights for the change from Daylight Savings Time to 
Standard Time and vice-versa to occur.

 

  Check for a 

WWVB

 Tower Icon showing on your Clock. The tower icon indicates you have 

received the WWVB signal from Ft Collins CO in the past 24-hours.  

  Check that the clock is in the correct 

Time Zone

.  

  Check whether the DST indicator is ON or OFF. If the indicator is OFF the clock will not 

change. 

  Check for fresh 

batteries

. Without proper batteries, the antenna will have a harder time 

picking up the signal.

 

  Position the clock in a window (

with the front or back

) facing Ft. Collins, Colorado and leave 

for up to five nights. If you do not have a window facing this direction, locate the clock near 
an outside wall and point the unit in this general direction.  

 

Is There a Booster Antenna 

 

  No. There is not a booster antenna available for the WWVB time signal. 

  There is not a signal booster available for the outdoor sensor signal. 

 

Can the Clock Attach to a Timer?  

 

  No timer circuit can be attached to the clock. Modifications will void the warranty. 

 

Clock Has Missing Segments 

 

  This is generally a power related issue.  

 

Batteries

 may be overpowered or underpowered. Remove batteries from clock.  

  Press any button 20 times. Leave the clock unpowered for 1-2 hours.  

  Insert fresh alkaline batteries with correct polarity.  

Digital Atomic Clock Is Dim 

 

  Most clock s have a gray background. Place the clock at eye level. Is it still dim? 

   Clocks that sit in the sunlight can develop a cloudy film over time. 

  This is generally a power related issue.  

 

Batteries

 may be overpowered or underpowered. Remove batteries from clock.  

  Press any button 20 times. Leave the clock unpowered for 1-2 hours. 

  Install fresh alkaline batteries with correct polarity.  

 

Digital Atomic Clock Has Distorted Display 

 

  On a brand new clock, check for thin plastic films of printed scratch guard that may be on 

the upper and lower screen of the clock. This thin piece of plastic has printed numbers for 
store displays.
