SETTING YOUR LOCAL  
TIME ZONE  
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

seconds and  
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.

every two seconds. The seconds

WWVB signal. See “Automatic

Page 7  
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.

mal conditions, a battery lasts about 6  
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  
Once you have plugged the clock into a  
standard AC outlet and have positioned  
the clock to receive a strong signal,  
The ACR-326 checks the WWVB time  
signal four times a day, at midnight, 6  
AM, noon, and 6 PM. When the clock re-  
ceives a good signal, it automatically  
sets the time and date. You can obtain  
more information about WWVB on the  
World Wide Web at:

every two seconds. Seconds should start  
to count up from 00 to 59 in one complete  
cycle without stopping or resetting. If the  
signal is poor, counting stops or starts  
over.  
Reposition the antenna until a complete  
count-up cycle finishes, then secure the  
antenna to the selected location. See  
“Setting Up the Antenna”.  
You can also set the ACR-326 manually.

the signal might not be strong enough to  
reset the clock. If the signal is interrupt-  
ed,-:-- appears and you should manually  
set the clock (see “Manually Setting the  
Clock” on Page 8).  
After you have found the best location for  
reception, attach the antenna bar to a  
window or to a wall using the appropriate  
hardware or double-sided tape (neither  
supplied).  
To turn off automatic time setting, re-  
peatedly press RX until the antenna sym-  
bol disappears.  
Note: Do not place the clock near a TV,  
high power cable, or metal table, be-  
cause these items could interfere with ra-  
dio signal reception.

Checking the Signal Status  
Daylight Savings Time (DST)  
The following chart shows the symbols  
for the current or last update to the radio  
reception.  
The WWVB radio signal adjusts for day-  
light saving time so the time displayed on  
the clock is accurate, regardless of the  
time of year. When the signal contains  
DST information,  
appears.  
Within the last 6  
hours, the signal

Hint: If you are in an area that does not  
use daylight saving time, press MODE

your local time (city) to one time zone  
west of where you are located. When  
DST ends, reset the clock to your city’s  
usual time zone.

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.
