Frequently Asked Questions - WT-3161BL LA CROSSE TECHNOLOGY

How do I set the time on my La Crosse Technology WT-3161BL clock?

The clock automatically sets itself after receiving the WWVB atomic signal. If you need to set manually, press and hold the SET button for 3 seconds, then use the +/- buttons to adjust time zone, DST, 12/24 hour, and time. Refer to the manual for detailed steps.

Why is my clock not receiving the atomic time signal?

Place the clock near a window, away from metal and electronic devices, at night for best reception. Ensure batteries are fresh. The clock attempts sync for up to 10 minutes after pressing the WWVB button. If it fails, try resetting by removing batteries for 10 seconds.

How do I change the batteries?

For the clock: open the battery compartment on the back and insert 2 fresh AA batteries (alkaline recommended). For the outdoor sensor: open the sensor's compartment and insert 2 AA batteries. Dispose of old batteries properly.

What is the outdoor temperature range for the remote sensor?

The remote sensor can measure temperatures from -40°F to 140°F (-40°C to 60°C). The transmission range is up to 330 feet (100 meters) in open air.

How do I switch between Fahrenheit and Celsius?

Press and hold the SET button for 3 seconds to enter settings. Use the +/- buttons to navigate to temperature unit, then press SET to toggle between °F and °C. Press SET again to confirm and exit.

My outdoor sensor shows '---' on the display. What should I do?

This indicates no reception. Check that the sensor is within range (330 ft) and the batteries are fresh. Press and hold the CH button on the clock to resync. Avoid interference from walls and electronics.

How do I set the alarm?

Press the ALARM button once to view alarm time. Press and hold ALARM for 3 seconds to set. Use +/- to adjust hour and minute, then press ALARM to save. The alarm icon will appear. To activate, press ALARM repeatedly until the icon shows.

Can I turn off the Daylight Saving Time adjustment?

Yes. Press and hold SET for 3 seconds, use +/- to find DST setting, then press SET to toggle between ON and OFF. Default is ON. If off, you must adjust time manually twice a year.

Why is the display dim?

The LCD display may become dim with low batteries. Replace the clock's batteries. If still dim, check the contrast/brightness setting (if available). In some models, pressing the SNOOZE/LIGHT button turns on backlight temporarily.

How do I perform a factory reset?

Remove all batteries from both clock and sensor. Wait 10 minutes. Reinstall batteries in the clock first, then in the sensor. The clock should start scanning for the atomic signal and sensor. Press and hold the RESET button (or a combination) if available. Refer to manual.

USER MANUAL WT-3161BL LA CROSSE TECHNOLOGY

16" Atomic Wall Clock

A Manual Time Setting Button
B Time Zone Selection Buttons
C Daylight Saving Time Button

Get Started

1: Slide the switch to select a time zone.
2: Insert 1 fresh AA, Alkaline battery according to the polarity marked on the case.
3: For the best reception, please place clock on a wall that faces Ft. Collins, Colorado. During the night, your clock will automatically set itself.

• When the battery is installed, the hands will move to the 12:00 position and search for the radio signal.
• If the radio signal is not received in the first 10 minutes, the clock will start running from the 12:00 position and will continue to run.
• The clock is searching for the WWVB signal and once the radio signal is decoded, the hands will automatically adjust to the correct time. This may take up to 5 nights if there is atmospheric interference.

Reset: If the clock does not respond to the various function modes, press the RESET button on the movement case.

Position Clock

• For the best reception, please place clock on a wall that faces Ft. Collins, Colorado. The antenna is best positioned for signal reception when there is only one wall or window between the clock and outside.
• 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.
• Large office buildings, schools, or hospitals may not receive the WWVB time signal in every room.
  • Buildings with a metal roof may interfere with reception.

Note: We recommend that you change the battery every 24 months to maintain accuracy. Remove the battery when the clock will not be in use for an extended period.

Manual Set Time

On rare occasions, the clock may not be able to utilize the radio controlled function because of 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.

Set the clock manually:

1. Hold the SET button for 3+ seconds to activate the manual mode. There are two ways to move the minute hand forward.

2. Hold the SET button down to move the minute hand forward consistently.

3. Alternatively, press the SET button rapidly (more than once per second) to move the minute hand forward step by step (in minute increments).
4. Use these features to move the minute hand forward until the correct time is set. The clock will automatically leave manual mode after the SET button is not pressed for 6+ seconds.

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 that faces Colorado.
• Weather – Electrical storms between you and Colorado during the night will interfere with the WWVB signal.
• Hands Spin- 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. Hands may spin if the battery is under powered or over powered.

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.

If you live in an area that does not recognize DST, you must slide the DST switch OFF. To reactivate the DST program simply slide the switch to the ON position.

Manual WWVB Time Signal Search

For WWVB information: www.nist.gov/pml/div688/grp40/wwvb.cfm

Manual Signal Search:

The WWVB signal is strongest at night.

• Hold the WAVE button down for 3+ seconds.
• The hands will automatically reset to the 12:00 position, and the clock will search for the WWVB time signal.
• If the clock receives the signal, the clock will set automatically to the correct time. The signal search takes approximately 3-8 minutes.
• Set the clock manually, and the movement's micro-CPU will control the time keeping function.

Frequently Asked Questions

Q. How long will the battery last?

A. A good AA alkaline battery will last over 24 months.

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

A: The clock cannot work on a timing circuit. Opening the clock voids the warranty.

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

A: The clock cannot work with a booster antenna. Opening the clock or movement voids the warranty.

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. The WAVE button will temporarily stop a WWVB search, but will not permanent stop the clock from receiving a WWVB time signal.

Care and Maintenance

• Always purchase the correct size and grade of battery suitable for intended use.
- Clean the battery contacts and also those of the device prior to battery installation.
- Ensure the battery installed with correct polarity (+and -).
- Remove battery from clock which is not to be used for an extended period of time.
- Remove expired battery promptly.
