Note: 
 
The clock will continuously search for WWVB at1:00 am, 3:00 am, 4:00 am, 6:00 am, 
12:00 pm, 6:00 pm and 11:00 pm until a signal is received. Once the WWVB time signal 
is received, the WWVB time will override the manual set time. 
 

TEMPERATURE AND HUMIDITY 
 

The Skyscan clock has two analog sensors that measure surrounding temperature and 
humidity. The temperature information is displayed in Fahrenheit and the Humidity data 
is displayed in percentage. 
 
The thermometer and hygrometer have been calibrated at the factory. To check the 
sensors accuracy, tune to your local weather forecast information broadcast for the latest 
weather information. It may be necessary to adjust the sensors. 
 
To manually adjust the sensors, gently turn the corresponding knobs located at the back 
of the clock until the required reading has been reached. 
 

TROUBLESHOOTING 
 

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

Battery:

 The SkyScan clock must have a fresh battery to receive and process the time 

signal. 
 

Location:

 Try a different location, ideally near a window. It 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. 
 

DAYLIGHT SAVINGS TIME 
 

The National Institute of Standards and Technology and WWVB encode a special DST 
"bit" in the WWVB transmission for DST. Your Skyscan clock will read this information 
and automatically advance the hands one hour in the spring and eleven hours in the fall. 
 

ARIZONA AND INDIANA 

 
If you live in an area that does not recognize DST you must press the (unmarked) DST 
button for one second to deactivate your clock's DST program. To reactivate the DST 
program simply press the DST button again for one second.
