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.

Set Time Zone
This atomic alarm clock offers four time zones:
Eastern
Central
Mountain
Pacific
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.
IMPORTANT: The clock will look for the WWVB time signal for 8 minutes when batteries are
first installed. Buttons will not function during this search period.
Press the WAVE button once to stop the WWVB signal search and manually set the time
and time zone.
The clock will search for the WWVB time signal again after midnight.

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 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
4. Leave without power for 15 minutes (very important).
5. Insert fresh batteries into the alarm clock.
6. Do not press buttons for 15 minutes.
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
Fahrenheit/Celsius
Press and release the ▼ button to switch the temperature display from Fahrenheit to
Celsius.
Inaccurate Indoor Temperature Reading
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 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.
Does the clock have a backlight?
Yes, this atomic alarm clock has a backlight. Press and release the SNOOZE/LIGHT button and
the backlight will show for 5 seconds, when operating on batteries only.
