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
La Crosse Technology, Ltd Page 2
This atomic wall clock offers seven time zones:
The atomic wall clock works in North America. Outside of North America, the atomic wall clock
will not receive a WWVB signal, but will keep time like a quartz clock.
Atomic Wall clock Factory Restart
Explanation: The factory restart returns the atomic wall clock to an “out-of-the-box” state and
often resolves an issue.
Factory Restart:
1. Remove all power from the wall clock.
2. Press one of the buttons on the wall clock at least 20 times to clear all memory.
3. Verify that the wall clock is blank
4. Leave without power for 15 minutes (very important).
5. Insert fresh batteries into the wall clock.
6. Do not press buttons for 5 minutes.
Fahrenheit/Celsius
Press and release the SET °F/°C button to switch the temperature display from Fahrenheit
to Celsius.
Inaccurate Indoor Temperature Reading
Batteries may be overpowered or underpowered. Remove power from the wall clock.
Press any button 20 times. Leave the wall clock unpowered for 1-2 hours.
Install fresh Alkaline batteries with correct polarity.
If the indoor temperature is, still contact support with the indoor temperature reading and the
reading of the comparative product.
Does the clock have a backlight?
No the wall clock does not have a backlight.
Time is off by hours
Check to see if the WWVB Tower icon appears on the atomic wall clock. If not, the atomic
wall clock has not received a WWVB time signal in the past 24 hours.
Reposition the atomic wall 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
La Crosse Technology, Ltd Page 3
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.
Check for a WWVB Tower Icon showing on the atomic wall clock. The tower icon indicates
you have received the WWVB signal from Ft Collins CO in the past 24 hours.
Check that the clock is in the correct Time Zone.
Check whether the DST indicator is ON or OFF. If the indicator is OFF the clock will not
change.
Check for fresh batteries. Without proper batteries, the antenna will have a harder time
picking up the signal.
Position the atomic wall clock in a window (with the front or back) facing Ft. Collins,
Colorado and leave for up to five nights. If you do not have a window facing this direction,
position the clock near an outside wall and point the unit in this general direction.

Atomic Wall clock has distorted or frozen display
Explanation: On a brand new wall clock, check for thin plastic film of printed scratch guard
that may be on the screen of the wall clock. This thin piece of plastic has printed numbers for
store displays. When the batteries are installed, the “real” numbers show behind the printed
scratch guard and create distortion.
With all power removed, the wall clock should be blank.
If numbers still appear, please check for scratch guard.
Power:
Check that the batteries are installed correctly.
This is generally a power related issue.
Batteries may be overpowered or underpowered.
Remove batteries from wall clock.
Press any button 20 times. Leave the batteries out of the display for 2 hours.
Insert and batteries into the wall clock.
Atomic Wall clock is blank: No letters, numbers or dashed lines
Check that the batteries are installed correctly.
Batteries may be overpowered or underpowered.
Remove batteries from wall clock.
Press any button 20 times. Leave the batteries out of the display for 2 hours.
Insert batteries into the wall clock.
Atomic Wall clock drains batteries quickly
Test a new set of alkaline batteries. Write down the date of installation and the voltage of the
batteries.
When the batteries fail, please note the date and voltage again. This is helpful in
determining the problem.
Check for leaking batteries, which may damage the wall clock.

Atomic Wall clock has missing segments
Explanation: When parts of numbers, letters, or pictures are missing on the display, it is often
power related.
With all power removed, the wall clock should be blank.
If numbers still appear, please check for scratch guard.
Power:
