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.

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.

 Batteries may be overpowered or underpowered. Remove power from the alarm clock.
 Press any button 20 times. Leave the alarm clock unpowered for 1-2 hours.
 Install the AC cord or fresh Alkaline batteries with correct polarity.
 If the indoor temperature is still shows dashes, HH.H or LL.L, the alarm clock may need replacement.
