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.

La Crosse Technology, Ltd Page 2
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:
E = Eastern
C = Central
M = Mountain
P = 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.
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 5 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
Use the program menu to change from Fahrenheit to Celsius.
Inaccurate Indoor Temperature Reading
Check for sources of heat near the clock.
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.

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 8 seconds, when operating on batteries only.
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.
Check for a WWVB Tower Icon showing on the atomic alarm 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 alarm 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.
