AC Power

The design of this alarm clock is to use AC power (5-volt) as primary power source.

When operating with the AC power cord, the backlight can be on continually.

When operating on AC power, batteries are optional and are not required in the alarm clock.

The backlight will turn off or operate at high or low intensity at your discretion.

La Crosse Technology, Ltd Page 2

Batteries

Explanation: Many problems are resolved with fresh batteries of the appropriate voltage. Many items

sent in under warranty work when tested with fresh batteries. Batteries manufactured this year will have

an expiration date 10 years (or more) in the future. Battery technology has improved and batteries will

maintain voltage longer in storage. However, the environment the batteries reside in for the 10 years can

deplete the power.

We suggest name brand Alkaline batteries for indoor displays.

A minimum voltage of 1.48V for each battery is necessary for proper performance.

Use batteries dated at least six years in advance of the current year. Batteries dated earlier than six

years from now may still work, but may be unstable in performance.

Good name brand batteries make less noise, which reduces the chance of RF (radio frequency)

interference from the battery compartment.

Atomic Alarm Clock Factory Restart

Explanation: The factory restart returns the atomic alarm clock to an “out-of-the-box” state and often

resolves an issue.

Factory Restart:

1. Remove all power (batteries and AC) from the alarm clock.

2. Press one of the buttons on the alarm clock at least 20 times to clear all memory.

3. Verify that the alarm clock is blank before proceeding (some lines are painted on and will not

disappear).

4. Leave without power for 15 minutes (very important).

5. Insert the AC power cord into the wall outlet then into the alarm clock.

6. Do not press buttons for 15 minutes.

Atomic Alarm Clock

12-Hour or 24-Hour Time Format

Display the time in 12-hour or 24-hour format

Default is 12-hour time

Use the Program Menu to switch time formats

Supported Time Zones

This atomic alarm clock offers seven time zones:

AST=Atlantic

EST= Eastern

CST= Central

MST= Mountain

PST= Pacific

AKT= Alaska

HAT=Hawaiian

The atomic alarm clock works in North America. Outside of North America, the atomic alarm clock will not

receive a WWVB signal, but will keep time like a quartz clock.

Fahrenheit/Celsius

Press and release the SET/°F/°C button on the top of the atomic alarm clock to switch the

temperature display from Fahrenheit to Celsius.

Inaccurate Indoor Temperature Reading

Explanation: These symbols are error messages indication the indoor sensor is outside of its readable

range. For indoor readings, this is generally a power related issue.

Press and release the SNOOZE/LIGHT HI-LO-OFF button and the backlight will show for 10 seconds,

when operating on batteries only.

IMPORTANT: During A/C power operation, the backlight and USB charging port will turn off while the

atomic alarm clock searches for the WWVB to avoid interference. The backlight will return after 4-8

minutes search (which occurs during the late night or early morning hours). The USB charging port will

then resume working.

Time is off by hours

Check to see if the WWVB Tower icon appears on the atomic alarm clock. If not, the atomic alarm

clock has not received a WWVB time signal in the past 24 hours.

Reposition the atomic alarm clock with the front or back facing Colorado.

Check that the Time Zone selected correctly reflects your location. Adjust the time zone in the

Program Menu.

Check that the DST indicator is correct for your location (most areas observe DST so this should be

ON). Adjust the DST indicator in the Program Menu.

Large buildings, metal roofed buildings and buildings or rooms full of electrical and/or radio equipment

make it difficult to receive the WWVB time signal.

Daylight Saving Time

Dependent on your location, position of the clock in your home, and atmospheric interference, it may

take up to 5 nights for the change from Daylight Savings Time to Standard Time and vice-versa to

occur.
