Thank you for purchasing your Worldwide Atomic Clock
from RadioShack. It receives signals from atomic clock
generators so you will always know the exact time. Your
clock automatically updates to the current local time
when you travel, and you can set it to automatically
update for Daylight Savings Time. The clock’s display
shows your home time, the local time (wherever you are
currently located), time zone, temperature, and day of
the week.
Depending on your location, you may or may not
receive an atomic clock signal. If you install batteries
and the signal strength indicator (
Ê
) does not appear,
you are in an area that does not receive a signal
from an atomic clock. See
“in regions not receiving
an atomic clock signal”
.
in regions receiving an atomic clock signal
The sequence for setting your clock in a region
receiving an atomic clock signal generator is:
1) automatic signal detection
2) select a city or time zone
3) set the home time
automatic signal detection
1. After batteries are installed, the clock starts
searching for an atomic clock signal and
Ê
flashes.
2. In about 10 minutes, one of the following
abbreviations appears momentarily to indicate
the atomic clock from which you are receiving a
signal:
Region

JP
Europe
EU
South Japan

• During automatic signal detection, you cannot manually
set the time. To override signal detection and manually
set the time, hold down
MODE
,
ON/OFF

• For best reception, keep the clock away from equipment
that emits RF or microwave signals, such as TVs, radios,
or microwaves.
• You may need to position your clock near a window for
best reception.
• The most dependable and clear signal is received at
night, between midnight and 4am local time.
• The clock receives an atomic signal update every 24
hours and will update accordingly for your location.
select a city or time zone
There are 32 cities and four US time zones stored
in your clock. Each city is represented by an
abbreviated name, and it’s GMT (Greenwich Mean
Time). GMT refers to that city or region’s time
relative to the International Date Line. For example,
Honolulu is ten hours behind (-10), and Tokyo is nine
hours ahead (+9) of the International Date Line.
1. Press

three times. An abbreviation flashes.
2. Press

to scroll until you see your home city. If
your home city is not listed, select the city listed
that is in your time zone.
