RADIO CONTROLLED ANALOG CLOCK

 

 

INSTRUCTION MANUAL 

 

Quick Setup Instructions 
Welcome to the world of atomic timekeeping technology. We hope you will enjoy 
the convenience of never having to set your clock again and the confidence of 
knowing exactly what time it is

 

 
 

 
 
 
 
 
 
 
 
 
 
 
 

 

 

Insert 1 new AA, LR6 1.5 volt ALKALINE battery into the digital clock battery 
compartment (the lower battery compartment) according to the polarity 
marked on the case, then 1 new battery AA, LR6 1.5 V into the analog clock 
battery compartment according to the polarity marked on the case.  

 

Once the battery is installed, the clock will begin searching for a signal.  For 
the initial setting, it is recommended to stand the clock in an upright position 
near a window.  Within five minutes the clock will either receive the WWVB 
signal and set itself to the exact time (for the default Pacific Time Zone), or it 
will determine that the signal is not receivable at its current location and time 
of day.  The clock will fast-forward the hands to the 4, 8, or 12 o’clock 
position immediately and search for WWVB at specific time each day until a 
signal is received.   

Note: 

If the time is manually set, the clock will continue to periodically 

search for a signal and automatically reset the hands when the signal is 
received. 

 

Once the clock has received the WWVB signal, press the time zone button 
to select your time zone. If you are in the Pacific Time Zone, no change is 
needed and you are ready to hang your clock. 
If you are not in the Pacific Time Zone, select your time zone by pressing 
one of the four time zone buttons PT-Pacific Time, MT-Mountain Time, CT-
Central Time, ET-Eastern Time and holding this button down for 5 seconds.  
If multiple buttons are pressed, the clock will set to the time zone selected 
last.  If no time zone is selected the clock will default to Pacific Time.  If you 
live in an area that does not recognize DST (Arizona) you must press the 
DST button (unmarked – just above and between the Central and Eastern 
time zone buttons) for one second to deactivate your clock’s DST program. 
For time zones outside of PT, MT, CT or ET you must manually set the time 
using the Manual Time set button on the back of the movement. (See 
instructions below).  
 

Please Note

: WWVB time will over ride a manual setting.
