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.
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 Clock Factory Restart

Explanation: The factory restart returns the atomic clock and remote sensor to an
“out-of-the-box” default state and often resolves an issue.
Factory Restart:
1. Remove batteries from atomic clock.
2. Press one of the buttons on the atomic clock at least 20 times to clear all memory.
3. Verify that the atomic clock is blank before proceeding (there may be lines painted on the screen that will show when there is no power).
4. Leave clock without power for 15 minutes (very important).
5. Install fresh batteries in the atomic clock.

Atomic clock

Power Requirements

2-AA alkaline batteries may be used.

12-Hour time format

Time can display in 12-hour only

Fahrenheit/Celsius

Use the program menu
to switch between Fahrenheit and Celsius.

HI | LO Records

Explanation: The atomic clock shows the daily HI | LO temperature and humidity records each day starting at midnight (12:00 AM). The atomic clock automatically resets the HI | LO records at midnight (12:00 AM).
• Press and release the PLUS button to view the HI temperature, than Humidity
record.
• Press and release the MINUS button to view the LO temperature, than Humidity
record.

Dashes, HH.H, LL.L or stuck Indoor Temperature | Humidity

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.
Page 2
Page 3
Batteries may be overpowered or underpowered. Remove batteries from the
atomic clock.
Press any button 20 times. Leave the atomic 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 atomic clock
may need replacement.

Inaccurate Indoor Temperature Reading

Explanation: When the indoor temperature is inaccurate, it is often due to the location of the display or overpowered/under powered batteries. You can test the accuracy at you home.
Side-by-side test: Bring the remote sensor in the house and place it next to the atomic clock for 2 hours. Compare indoor and remote temperature. The temperature should be within 4
degrees to be within tolerance. Look for heat sources such as sunlight, door or window frames or reflected heat
or cold near the atomic clock.

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 (On this clock, please
change the DST setting to OFF unless you live in Arizona). 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 t he 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. On this clock, please change the
DST setting to OFF unless you live in Arizona. Check for fresh batteries. Without proper batter ies, the antenna w ill 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.

Atomic clock is dim

Explanation: Most atomic clocks have a dark background. Place the atomic clock at eye level, to determine if it is dim. Atomic clocks that sit in the sunlight can develop a cloudy film over time.
This is generally a power related issue. Batteries
may be overpowered or underpowered. Remove batteries from atomic
clock.
Press any button 20 times. Leave the atomic clock unpowered for 1-2 hours. Install fresh alkaline batteries with correct polarity.

Atomic clock has distorted or frozen display

Explanation: On a brand new atomic clock, check for thin plastic film of printed scratch guard that may be on the screen of the atomic 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 atomic 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 atomic clock.  Press any button 20 times. Leave the batteries out of the display for 2 hours.  Insert batteries into the atomic clock.

Atomic 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 atomic clock. Press any button 20 times. Leave the batteries out of the display for 2 hours. Insert batteries into the atomic clock.

Atomic 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 atomic clock.

Atomic clock has missing segments

Explanation: When parts of numbers, letters, or pictures are missing on the displa y , it is ofte n power related.
Batteries
may be overpowered or underpowered. Remove batteries from atomic
clock.
Press any button 20 times. Leave the atomic clock unpowered for 1-2 hours. Install fresh alkaline batteries with correct polarity.
