Q: How do I adjust the Temperature or Humidity? 

A:

 Use a flat tipped screwdriver to gently turn the temperature or 

humidity sensor screw at the back of the clock, until desired setting has 
been reached. 

 

Troubleshooting 

 

The wonderful advantage of owning a radio-controlled clock is that it is 
virtually trouble free. If the clock receives a clear time signal, it will set 
itself perfectly. If it does not receive a time signal, consider the following: 

 

Battery: 

The clock must have a fresh battery to receive and process 

the time signal. 

 

Location: 

Try a different location, ideally near a window. Your clock 

should be at least six feet from computers, TVs, air conditioners, 
other radio-controlled clocks and other electrical appliances that 
cause interference. 

 

Weather: 

Electrical storms between you and Colorado during the 

night will interfere with the WWVB signal. 

 

Care and Maintenance

Do not mix Alkaline, Standard, Lithium or Rechargeable 
Batteries
