FEATURES

Your Optimus Atomic Clock Radio combines a simple design with advanced technology. It automatically updates the clock setting by receiving a 60 kHz longwave radio signal from station WWVB which broadcasts the time 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 most 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 with no installation.

Display Shows Home Time, World Times, Date, and Calendar — to provide you with accurate, complete information.

Backlit Display — lets you see the display in low light situations.

Sleep Timer — lets you set the radio to play as you fall asleep, then automatically 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.

PREPARATION

CONNECTING AC POWER/ SETTING YOUR LOCAL TIME ZONE

Plug the clock radio’s power cord into a standard AC outlet. As soon as you connect AC power, all display segments briefly appear, then the following appear:

LAX (indicating the time zone for

Los Angeles) flashes for about 15 seconds and flashes. WhileLAX flashes, set your local time zone at this point by selecting a city in your time zone from the chart on Page 8, repeatedly pressingUP orDOWN until that city appears, then pressingMODE once to store your selection.

Note: IfLAX stops flashing before you pressUP orDOWN, unplug the clock radio, wait about 30 seconds, then plug the clock radio back in and repeat the above procedure.

-:-- and00 appear andflashes every two seconds. The seconds start to count up from00 to59 while the radio searches for a good WWVB signal. See “Automatic Time/Date Setting” on Page 6 and “Checking the Signal Status” on Page 7

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.

INSTALLING A BACKUP BATTERY

To keep the clock running for up to 8 hours during an AC power failure, install a 9-voltbattery (not supplied) in the battery compartment. For the longest life, we recommend a RadioShack alkaline battery.

Caution: Use only a fresh battery of the required size and recommended type.

Note: To prevent unnecessary drain on the battery, plug in the power cordthen install the battery.

Follow these steps to install a back-upbattery.

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.

3.Replace the cover.

3

12-1626.fmPage 4 Friday, January 14, 2000 9:32 AM

When appears, check or replace the backup battery. When you connect a new battery,disappears. PressSNOOZE to reset the backup battery monitor if thedoes not disappear with a new battery installed. Under normal conditions, a battery lasts about 6 months.

Warning: Always dispose of an old battery 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-326is operating only on battery power.

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. Replace the battery and reset the clock.

PREPARATION

AUTOMATIC TIME/DATE SETTING

The ACR-326checks 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 and 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-326manually. 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-sidedtape (neither supplied).

Note: Do not place the clock near a TV, high power cable, or metal table, because these items could interfere with radio signal reception.

Auto-Settingthe Clock

Once you have plugged the clock into a standard AC outlet and have positioned the clock to receive a strong signal, -:-- and00 appear andflashes 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-upcycle finishes, then secure the antenna to the selected location. See “Setting Up the Antenna”.

If the clock receives a strong radio signal, the clock’s time and date are set automatically. appears steadily. This process takes from 2 to 5 minutes.

Note: On very cloudy and stormy days, 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).

To turn off automatic time setting, repeatedly press RX until the antenna symbol disappears.

Daylight Savings Time (DST)

The WWVB radio signal adjusts for daylight saving time so the time displayed on the clock is accurate, regardless of the time of year. When the signal contains DST information, appears.

Hint: If you are in an area that does not use daylight saving time, pressMODE five times then pressDOWN once to set your local time (city) to one time zonewest of where you are located. When DST ends, reset the clock to your city’s usual time zone.

RESETTING YOUR LOCAL TIME ZONE

The clock radio is preset to the Pacific Standard (LAX) time zone.

Follow these steps to select a different local time zone if you have already set a time zone.

Note: The time zone you set will take effect the next time the clock synchronizes with WWVB.

1.Select a city in your time zone from the chart at the end of this section.

Note: Time zones designated by their UTC number indicate that no known city exists in that part of the globe. Typically these zones include major sections of ocean.

2.Press MODE five times. The currently selected city flashes while the time setting disappears.

SETTING THE WORLD

TIMES

For the purpose of timekeeping, the globe is divided into 24 time zones. The 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 the UTC starting point. The clock’s initial setting of LAX (for example) is–8hours 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 different time zone) appears.

2.Select a city that is in the desired world time zone from the chart in
