Thank you for purchasing a RadioShack 1.8 Inch Big Digit Atomic Clock. Your clock tells Atomic 
time, so it sets itself automatically when it receives the WWVB signal transmitted by NIST in 
Fort Collins, Colorado. It has a bold, easy to read display with a Hi-Lo dimmer that allows you to 
adjust the brightness for greater readability. With four time zones selection, you can set the 
clock to the correct time by just sliding a switch!

You can install a backup battery so you do 
not lose your clock settings if there is a power 
failure. The display turns off during a power 
failure, but, for 24 hours, the clock continues 
to run and the alarms sound at the preset 
alarm times.

Your clock requires one 9V battery (not 
supplied) for backup power. For the best 
performance and longest life, we recommend 
RadioShack alkaline batteries.
