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.
1. Slide the battery compartment cover in
the direction of the arrow to remove it.
2. Place the battery in the compartment as
indicated by the polarity symbols
(+ and –) marked inside.
3. Replace the cover.
