FEATURES
Your Optimus Atomi c Clock Radi o combines a simple design with advanced
technology. It automati cally updates the
clock setting by receiving a 60 kHz longwave radio signal from station WWVB
which broadcasts the t ime according to
the U.S. government’s atomic clock in
Boulder, Colorado. The clock checks this
continuous signal several times each
day, giving you the mo st accurate time
possible. Its features include:
World Times Display
— lets you see
the current time for the United States
time zones and up to 24 world cities.
NASA (National Aeronautics and
Space Administration) and Military
Time Accuracy
— the Colorado radio
signal provides an exact standard for
your home or business.
WWVB External Antenna
— receives
the atomic clock signal wi th no installation.
Display Shows Home Time, World
Times, Date, and Calendar
— to provide you with accurate, complete information.
3" Speaker
— provides excellent r adio
fidelity.
AM/FM Radio
— lets you wake to pro-
grams on your favorite broadcast station.
Backlit Display
— lets you see the dis-
play in low light situations.
Sleep Timer
— lets you set the radio to
play as you fa ll as leep, t hen aut omat ically turn off.
Snooze Bar
— lets you temporarily turn
off the alarm or radio for about 9 minutes
so you can get a few extra minutes of
sleep.

that can destroy electronic parts.
Notes:
• The display does no t light when the

• A prolonged power failure can drain
the battery. If the display flashes
after an AC power failure, the battery is too low to run the clock.

AUTOMATIC TIME/DATE
SETTING
The ACR-326 checks the WWVB time
signal four times a day, at midnight, 6
AM, noon, and 6 PM. When the clock receives a good signal, it automatically
sets the time an d date. You can obtain
more information about WWVB on the
World Wide Web at:
www.bldrdoc.gov/timefreq/wwvstatus.htm
You can also set the ACR-326 manually.
See “Manually Setting the Clock” on
Page 8.
Setting Up the Antenna
To ensure good reception, fully extend
the antenna bar’s cable away from the
clock and as near a window as possible.
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).
Do not place the c lock near a TV,

SETTING THE WORLD
TIMES
For the purpose of timekeeping, the
globe is divided into 24 time zones. T he
zone where Greenwich, England is located 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 described as “Greenwich Mean Time”
(GMT).
For clarity, the “GMT” reference was recently changed to “UTC,” which stands
for Universal Time Coordinate. The radio 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 th e UTC starting
point. The clock’s initial setting of
(for example) is –8 hours wit h r es pect to
the UTC.

RESETTING THE CLOCK
On rare occasions, your clock might not
work properly or it might lock up. If that
happens, follow the se steps to reset the
clock. If you still encounter difficulties,
take it to your local RadioShack store for
assistance.
1. Disconnect the AC power cord and
remove the back-up battery.
2. Reconnect the clock radio to AC
power and reinstall the battery.
THE FCC WANTS YOU TO
KNOW
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 interference goes away, your clock radio is
causing it. Try to eliminate the interference by:
• moving your cloc k radio away from
the TV or radio
• connecting your clock radio to an
outlet that is on a different electr ical
circuit from the TV or radio
• contacting your local RadioShack
store for help
If you cannot eliminate t he interference ,
the FCC requires that you stop using the
clock radio.

CARE AND MAINTENANCE
Your Atomic Clock Radio i s an example of sup erior d esign an d cr aftsmans hip. T he
following suggesti ons will help you care for yo ur clock radio so you can enjo y it for
years.
Keep the clock radio d ry. If it gets wet, wi pe it dry immedi ately. Liquids
might contain minerals that can corrode the electronic circuits.
Use and store the clock radio only in normal temperature environments.
Temperature extremes can s horten the life of electronic dev ices, damage batteries, and distort or melt plastic parts.
Keep the clock radio away from dus t and di rt, which c an caus e premature wear of parts.
Handle the clock radio gently and carefully. Dropping it can damage circuit boards and ca se s and can c ause the cloc k radi o to wo rk i mproper ly.
Use only a fresh bat tery of the required size and re commended type.
Batteries can lea k chemicals tha t damage your clock radio’s electroni c
parts.
Wipe the clock ra dio with a damp cloth oc casionally to keep it looking
new. Do not use h arsh chemicals, cleaning solv ents, or strong detergents 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 authorization to operate it. If your clock radio is no t pe rf orming as it should, t ake i t to your local RadioShack store for assistance.
