29.The date will flash. (Day of the week will set automatically) 

30.Press and release the + or - buttons to set the date. 

31.Confirm all calendar settings with the SETTINGS button and select 

Fahrenheit/Celsius. 

32.°F will flash.              

33.Press and release the + or - buttons to select Celsius.  

34.Confirm with the SETTINGS button and exit. 

 

Does the clock have a backlight? 

 

 

No, as this clock is battery operated there is no backlight. 

 

 

Time is off by hours 

 

 

Check to see if the 

WWVB

 Tower icon appears on the atomic digital clock. If not, 

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

 

Reposition the digital clock with the front or back facing Colorado. 

 

Check that the 

Time Zone 

selected correctly reflects your location. Adjust the 

time zone in th

Program Menu.

 

 

Check that the DST indicator is correct for your location (On this clock, please 

change the DST setting to OFF unless you live in Arizona). Adjust the DST 

indicator in the 

Program Menu.

 

 

Large buildings, metal roofed buildings and buildings or rooms full of electrical 

and/or radio equipment make it difficult to receive the WWVB 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 the atomic digital 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. On this clock, please change the 

DST setting to OFF unless you live in Arizona. 

 

Check for fres

batteries

. Without proper batteries, the antenna will have a 

harder time picking up the signal. 

 

Position the digital 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, position the clock near an outside wall and point the unit in this 

general direction.  

 

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. 

 

This is generally a power related issue.  

 

Batteries 

may be overpowered or underpowered. Remove batteries from atomic 

clock.  

 

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