Frequently Asked Questions - WT-971 L LA CROSSE TECHNOLOGY

How do I set the time manually on my WT-971 L?

Press and hold the SET button for 3 seconds until the hour digits flash. Use the + or - buttons to adjust. Press SET again to adjust minutes, year, date, etc. Finally, press SET to exit.

Why is my clock not receiving the atomic signal?

Place the clock near a window facing Colorado (direction of the WWVB transmitter) at night when signals are strongest. Ensure no metal obstructions. It may take up to 2-5 nights to sync automatically.

How do I change the temperature unit from Fahrenheit to Celsius?

Press the °F/°C button on the back of the clock to toggle between Fahrenheit and Celsius display.

What type of batteries does the WT-971 L use?

It requires 2 AA alkaline batteries. Do not use rechargeable batteries as they may not provide enough voltage.

How do I turn on the backlight?

Press the LIGHT button on the top or side of the clock. You can select between Low, High, and Auto (lights up when you press the button) by repeatedly pressing the LIGHT button.

Is there a snooze function on the alarm?

Yes, when the alarm sounds, press the SNOOZE button (usually the LIGHT button) to delay for 5 minutes. The alarm will repeat.

How do I turn off the alarm?

To deactivate the alarm completely, press the ALARM ON/OFF button until the alarm icon disappears from the display.

Can I mount this clock on the wall?

Yes, the clock has a keyhole slot on the back. Use a nail or screw to hang it, ensuring it is secure and level.

What is the accuracy of the atomic time?

When synced with the WWVB signal, the time is accurate to within 1 second of official US atomic time. Without sync, it remains accurate to about ±1 minute per month.

How do I reset the clock to factory defaults?

Press and hold the RESET button (usually on the back) with a pin or paperclip for 3 seconds. This will clear all settings and restart the atomic sync process.

WWVB-RADIO CONTROLLED WATCH

The NIST (National Institute of Standards and Technology-Time and Frequency Division) WWVB radio station is located in Ft. Collins, Colorado, and transmits the exact time signal continuously at 60 kHz. The signal can be received up to 2,000 miles away through the internal antenna in the La Crosse Technology watch. However, due

to the nature of the Earth's Ionosphere, reception is very limited during daylight hours.

The Watch will search for a signal every night when reception is best. The WWVB radio station derives its signal from the NIST Atomic clock in Ft. Collins, Colorado. A team of atomic physicists is continually measuring every second, of every day, to an accuracy of ten billionths of a second per day. These physicists have created an international standard, measuring a second as 9,192,631,770 vibrations of a Cesium-133 atom in a vacuum. This watch is regulated by the WWVB transmitter.

2. Place the watch on a steady surface for better reception. Prior to WWVB reception (and 15 seconds after holding the PUSH-PIECE) the hands will automatically return to the manually set time. The watch is now set to the WWVB signal reception mode. If the reception is disturbed (ex: close proximity to metallic objects or electric appliances), the watch will automatically try several times to receive the WWVB signal.

ADJUSTING THE HANDS

If the time is displayed incorrectly despite successful WWVB signal reception, the hands may have been moved by mechanical influences and will need to be adjusted manually.
