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

La Crosse Technology, Ltd Page 2
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.
Digital Clock Factory Restart
Explanation: The factory restart returns the clock and outdoor sensor to an “out-of-the-
box” default state and often resolves an issue.
Factory Restart:
1. Remove all power from clock.
2. Press one of the buttons on the clock at least 20 times to clear all memory.
3. Verify that the clock is blank before proceeding (there may be lines painted on the
screen that will show when there is no power).
4. Leave without power for 15 minutes (very important).
5. Insert fresh batteries into the clock.
Display Indoor Temperature or Seconds
Press the MODE button to toggle between indoor temperature, or seconds.
This is a normal feature of the clock.
Fahrenheit/Celsius
Use the program menu to switch from Fahrenheit to Celsius.
12-Hour Time Format
Use the program menu to switch from select 12-hour or 24-hour time format..
Supported Time Zones
This clock has 7 Time Zones: AST=Atlantic, EST= Eastern, CST= Central,
MST= Mountain, PST= Pacific, AKT= Alaska, HAT=Hawaiian The digital clock works in
North America.
Outside of North America, the digital clock will not receive a WWVB signal, but will
keep time like a quartz clock.
Dashes, HHH, LLL or Stuck Indoor Temperature

La Crosse Technology, Ltd Page 3
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.
This is generally a power related issue.
Batteries may be overpowered or underpowered. Remove batteries from atomic digital
clock.
Press any button 20 times. Leave the digital clock unpowered for 1-2 hours.
Insert fresh alkaline batteries with correct polarity.
If the indoor temperature is still dashes or HHH, LLL, the digital clock may need
replacement.
Does the clock have a backlight?
No, as this clock is battery operated there is no backlight.
Time is off by hours
Check to see if the WWVB Tower icon appears on the atomic digital clock. If not, the
digital clock has not received a WWVB time signal in the past 24 hours.
Reposition the digital 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 digital 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 digital 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.

Digital clock has distorted or frozen display
Explanation: On a brand new digital clock, check for thin plastic film of printed scratch
guard that may be on the screen of the digital 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 digital clock should be blank.
If numbers still appear, please check for scratch guard.
