BATTERY
To keep the clock running for up to 8
hours during an AC power failure, install
a 9-volt battery (not supplied) in the bat-
tery compartment. For the longest life,
we recommend a RadioShack alkaline
battery.
Plug the clock radio’s power cord into a
standard AC outlet. As soon as you con-
nect AC power, all display segments
briefly appear, then the following ap-
pear:

Los Angeles) flashes for about 15

flashes. While LAX
flashes, set your local time zone at
this point by selecting a city in your
time zone from the chart on Page 8,
repeatedly pressing UP or DOWN
until that city appears, then pressing
MODE once to store your selection.
Note: To prevent unnecessary drain on
the battery, plug in the power cord then
install the battery.
Follow these steps to install a back-up
battery.
Note: If LAX stops flashing before
you press UP or DOWN, unplug the
clock radio, wait about 30 seconds,
then plug the clock radio back in and
repeat the above procedure.

1. Slide the battery compartment cover
in the direction of the arrow and
remove it.
2. Snap the battery onto the connector
in the compartment and place the
battery in the compartment.
Caution: The clock radio’s AC power
cord is equipped with a polarized plug to
prevent electric shock. One blade on the
cord’s plug is wider than the other and
the plug only fits an outlet one way. If you
can not easily insert the plug, turn it over
and try again. Do not force it.
3. Replace the cover.

with a new battery installed. Under nor-

months.
Warning: Always dispose of an old bat-
tery promptly and properly. Do not burn
or bury it.
Caution: Always remove an old or weak
battery. Batteries can leak chemicals
that can destroy electronic parts.
Notes:
• The display does not light when the
ACR-326 is operating only on bat-
tery power.
• A prolonged power failure can drain
the battery. If the display flashes
after an AC power failure, the bat-
tery is too low to run the clock.
Replace the battery and reset the
clock.

SETTING THE WORLD
TIMES
For the purpose of timekeeping, the
globe is divided into 24 time zones. The
zone where Greenwich, England is lo-
cated is considered the starting zone
(represented by 12:00 in the chart on
Page 15). The time in every other zone
is set based on the time in Greenwich,
England; therefore, the times were de-
scribed as “Greenwich Mean Time”
(GMT).
For clarity, the “GMT” reference was re-
cently changed to “UTC,” which stands
for Universal Time Coordinate. The ra-
dio station WWVB transmits the time
based on the starting UTC time zone
(12:00). By setting your local city, you
program the clock a certain number of
hours ahead or behind the UTC starting
point. The clock’s initial setting of LAX
(for example) is –8 hours with respect to
the UTC.
Follow these steps to set a second
(world) time zone.
1. Press MODE six times. The time
appears and another city (in a differ-
ent time zone) appears.
2. Select a city that is in the desired
world time zone from the chart in

RESETTING THE CLOCK
THE FCC WANTS YOU TO
KNOW
On rare occasions, your clock might not
work properly or it might lock up. If that
happens, follow these steps to reset the
clock. If you still encounter difficulties,
take it to your local RadioShack store for
assistance.
Your clock radio might cause TV or radio
interference even when it is operating
properly. To determine whether your
clock radio is causing the interference,
turn off your clock radio. If the interfer-
ence goes away, your clock radio is
causing it. Try to eliminate the interfer-
ence by:
1. Disconnect the AC power cord and
remove the back-up battery.
2. Reconnect the clock radio to AC
power and reinstall the battery.
• moving your clock radio away from
the TV or radio
• connecting your clock radio to an
outlet that is on a different electrical
circuit from the TV or radio
• contacting your local RadioShack
store for help
If you cannot eliminate the interference,
the FCC requires that you stop using the
clock radio.

CARE AND MAINTENANCE
Your Atomic Clock Radio is an example of superior design and craftsmanship. The
following suggestions will help you care for your clock radio so you can enjoy it for
years.
Keep the clock radio dry. If it gets wet, wipe it dry immediately. Liquids
might contain minerals that can corrode the electronic circuits.
Use and store the clock radio only in normal temperature environments.
Temperature extremes can shorten the life of electronic devices, dam-
age batteries, and distort or melt plastic parts.
Keep the clock radio away from dust and dirt, which can cause prema-
ture wear of parts.
Handle the clock radio gently and carefully. Dropping it can damage cir-
cuit boards and cases and can cause the clock radio to work improper-
ly.
Use only a fresh battery of the required size and recommended type.
Batteries can leak chemicals that damage your clock radio’s electronic
parts.
Wipe the clock radio with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong deter-
gents to clean the clock radio.
Modifying or tampering with the Atomic Clock Radio’s internal components can
cause a malfunction and might invalidate its warranty and void your FCC authoriza-
tion to operate it. If your clock radio is not performing as it should, take it to your lo-
cal RadioShack store for assistance.
