Frequently Asked Questions - WT-3181P LA CROSSE TECHNOLOGY

How do I set the time on my La Crosse Technology WT-3181P?

Insert a fresh AA battery into the clock. The hands will automatically advance to the correct time if the clock is atomic. If it is a manual set clock, turn the knob on the back to set the time.

Why is the clock not working?

Check if the battery is inserted correctly with the correct polarity. Replace the battery with a new one. Ensure the clock is not exposed to extreme temperatures or moisture.

What type of battery does the WT-3181P use?

The clock requires one AA battery (alkaline recommended). Do not use rechargeable batteries as they may not provide sufficient voltage.

Is the clock atomic?

The WT-3181P model is typically an analog clock without atomic time sync. It requires manual adjustment. Please refer to the product packaging to confirm.

How do I mount the clock on the wall?

Use a screw or nail that fits the keyhole hanger on the back of the clock. Ensure it is securely fastened to the wall.

The clock is running fast or slow. What should I do?

Quartz clocks are generally accurate. If the clock is consistently off, replace the battery first. If the problem persists, the movement may be faulty and the clock should be replaced.

Can I use the clock outdoors?

The clock is designed for indoor use only. Exposure to outdoor elements may damage the clock.

How do I clean the clock?

Wipe the clock with a soft, dry cloth. Do not use water, solvents, or abrasive cleaners as they may damage the finish.

Where can I find a replacement battery cover?

Contact La Crosse Technology customer service for spare parts. Battery covers are often available for purchase.

What is the warranty on the WT-3181P?

La Crosse Technology offers a 1-year limited warranty from the date of purchase against defects in materials and workmanship.

18" Indoor/Outdoor Atomic Wall Clock

Get Started

Step 1: Remove the round battery cover from the back of the clock.

Step 2: Insert 1 fresh AA, LR6 1.5 volt ALKALINE battery according to the polarity marked on the case. Replace the battery cover.

Step 2: Firmly press the time zone button once.

Step 3: Position the clock on an exterior wall that faces Ft. Collins, Colorado. During the night, your clock will automatically set itself. Note: The hands will move to the 12:00, 4:00 or 8:00 position and search for the radio signal. If the radio signal is received the time will set. If the signal is not received the clock will stay at the 12:00, 4:00 or 8:00 position and search for the WWVB time signal on the even hours. Once the radio signal is decoded, the hands will automatically adjust to the correct time. This may take up to 5 nights.

Step 4: The default time zone is Pacific Time. If the clocks sets itself and the hours are off, hold the correct time zone button for 5 seconds to correct.

Position Clock

• Indoor: Choose a location 6 feet or more from electronics such as cordless phones, wireless gaming systems, televisions, microwaves, routers, baby monitors, etc., which can prevent signal reception.

• Position near an exterior wall that faces Ft. Collins, Colorado for WWVB time signal reception.

• The antenna is available for signal reception when the front or back of the clock faces Colorado.

• Outdoor: Choose a location with an overhang to protect the clock from the overhead sun or standing snow or rain.
• A shaded location will prevent inaccurate temperature readings. Mount the clock on a wall with the hanging hole on the back of the clock. Be sure the battery cover is on snug.

Manual Set Time

On rare occasions in certain areas, the clock may not be able to receive the radio controlled time signal due to the strength of the signal or the geographic location.

In this case, the clock can be set manually and used as a regular quartz wall clock.

Note: Allow up to five nights for the clock to receive the WWVB signal before manually setting the time.

Set the clock manually:

1. Remove battery for 15 minutes and press the Manual Set Tab 20 times.
2. After 15 minutes, insert the battery and allow the clock to spin to 12:00, 4:00 or 8:00.
3. Hold the Manual Set Tab and the hand will spin. Continue holding until the correct time is achieved.

Note: You can only set the clock manually for about 2 minutes after the battery is inserted. If the clock receives the WWVB time signal, this signal will override manually set time.

Temperature and Humidity

The La Crosse Technology® atomic wall clock has two analog sensors that measure surrounding temperature and humidity. The temperature information is displayed in degrees Fahrenheit and Celsius, and humidity data is displayed in percentage.

The thermometer and hygrometer have been calibrated at the factory. To check the sensors accuracy, tune to your local weather forecast information broadcast for the latest weather information. The sensors may be adjusted.

To manually adjust the sensors, use a flat tipped screwdriver to gently turn the temperature or humidity sensor screw at the back of the clock until desired setting has been reached.

Daylight Saving Time

The National Institute of Standards and Technology and WWVB encode a special DST "bit" in the WWVB transmission for DST. Your clock will read this information and automatically advance the hands one hour in the spring and eleven hours in the fall.

Arizona: If you live in an area that does not recognize DST, you must press the DST button one time only to turn OFF.

Manual WWVB Time Signal Search

Signal Interference

In some cases, the signal is affected by weather conditions and electrical interferences, or the location of the clock itself may result in poor reception. If the clock has not synchronized to the correct time within a few days of activation, you may need to move the clock to a different location.

Frequently Asked Questions

Q. How long will the battery last?

A. A good AA alkaline battery will last over 12 months.

Q: Is there a version of analog clock with more than the four continental US times zones?

A: La Crosse Technology ^® does not make an analog clock with more than four time zones. These time zones are PT (Pacific Time), MT (Mountain Time), CT (Central Time), and ET (Eastern Time).

Q: Can I shut off the WWVB signal?

A: No. If you manually set the time, when the clock receives a WWVB signal, that signal will override the manual set.

Q: Is there a booster antenna to receive the WWVB signal in a difficult location?

A: No, the clock cannot work with a booster antenna. Opening the clock or movement voids the warranty.

Q: Can I wire a control timing circuit to the La Crosse Technology® atomic clock?

A: No, the clock cannot work on a timing circuit. Opening the clock voids the warranty.

Q: Why do the hands spin?

A: When the hands spin about the same time every day the clock is auto-correcting the time. The hour hand should not spin more than twice around the clock.

A: Hands may spin if the battery is under powered or over powered. Use only Alkaline batteries in the clock.

Q: How do I adjust the Temperature or Humidity?

A: Use a flat tipped screwdriver to gently turn the temperature or humidity sensor screw at the back of the clock, until desired setting has been reached.

Troubleshooting

The wonderful advantage of owning a radio-controlled clock is that it is virtually trouble free. If the clock receives a clear time signal, it will set

itself perfectly. If it does not receive a time signal, consider the following:

• Battery: The clock must have a fresh battery to receive and process the time signal.
• Location: Try a different location, ideally near a window. Your clock should be at least six feet from computers, TVs, air conditioners, other radio-controlled clocks and other electrical appliances that cause interference.
• Weather: Electrical storms between you and Colorado during the night will interfere with the WWVB signal.

Care and Maintenance

• Do not mix old and new batteries
  • Do not mix Alkaline, Standard, Lithium or Rechargeable Batteries
• Always purchase the correct size and grade of battery most suitable for intended use.
• Replace all batteries of a set at the same time.
