Central Time 

 

Position near an exterior wall that faces Ft. Collins, Colorado for 
WWVB time signal reception. 

 

The antenna is available for signal reception when the front or back 
of the clock faces Colorado. 

 

Outdoor:

 Choose a location with an overhang to protect the clock 

from the overhead sun or standing snow or rain.  

 

A shaded location will prevent inaccurate temperature readings. 
Mount the clock on a wall with the hanging hole on the back of the 
clock. Be sure the battery cover is on snug. 

 

Manual Set Time 

 
On rare occasions in certain areas, the clock may not be able to receive 
the radio controlled time signal due to the strength of the signal or the 
geographic location.   
In this case, the clock can be set manually and used as a regular quartz 
wall clock.  

 
 

      

 
 
 
 

 
 

 
 
 
 
 

 

Note:

 Allow up to five nights for the clock to receive the WWVB signal 

before

 manually setting the time.  

  

Set the clock manually: 

1. 

Remove battery for 15 minutes and press the 

Manual Set Tab

 20 

times. 

2. 

After 15 minutes, insert the battery and allow the clock to spin to 
12:00, 4:00 or 8:00. 

3. 

Hold the 

Manual Set Tab

 and the hand will spin.  Continue holding 

until the correct time is achieved. 

Note:

 You can only set the clock manually for about 2 minutes after 

the battery is inserted. If the clock receives the WWVB time signal,
