Position Clock 

 

  For the best reception, please place clock on a wall that faces 

Ft. Collins, Colorado. The antenna is best positioned for signal 
reception when there is only one wall or window between the 
clock and outside. 

  Choose a location 6 feet or more from electronics such as 

cordless phones, wireless gaming systems, televisions, 
microwaves, routers, baby monitors, etc., which can prevent 
signal reception. 

  Large office buildings, schools, or hospitals may not receive 

the WWVB time signal in every room. 

  Buildings with a metal roof may interfere with reception.  

 

Note:  

We recommend that you change the battery every 24 

months to maintain accuracy.  Remove the battery when the clock 
will not be in use for an extended period. 

 

Manual Set Time 

 

On rare occasions, the clock may 
not be able to utilize the radio 
controlled function because of 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. 

Hold the SET button for 3+ seconds to activate the manual 
mode.  There are two ways to move the minute hand forward.  

 

Hold the SET button down to move the minute hand 
forward consistently.   

 

Alternatively, press the SET button rapidly (more than once 
per second) to move the minute hand forward step by step 
(in minute increments).  

 

Use these features to move the minute hand forward until 
the correct time is set.  The clock will automatically leave 
manual mode after the SET button is not pressed for 6+ 
seconds.
