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!
WARNING: To reduce the risk of fire or
shock hazard, do not expose this product to rain
or moisture.
