Frequently Asked Questions - WT-981-C LA CROSSE TECHNOLOGY
How does the watch set the time automatically?
The watch receives a radio signal from the atomic clock (WWVB in the US or DCF77 in Europe) and updates the time automatically, usually overnight. Ensure the watch is placed near a window with good reception.
What should I do if the watch fails to sync?
Try placing the watch near a window facing the signal tower (Colorado for WWVB). Avoid metal surfaces and electronic interference. You can also manually set the time or force a sync by pressing the RECEIVE button (if available).
How do I change the battery?
Use a small screwdriver to open the battery compartment on the back. Replace the old CR2032 battery with a new one, ensuring the + side faces up. Close the cover and press any button to reset.
How do I set the alarm and snooze?
Press the ALARM button to enter alarm setting mode. Use the SET button to adjust hours and minutes. To enable snooze, press the SNOOZE button when the alarm sounds; it will repeat after 5 minutes.
How do I switch between 12h and 24h time format?
In normal time mode, press and hold the SET button for 3 seconds. Use the +/– buttons to toggle between 12H and 24H. Confirm with SET.
Is the watch water resistant?
The watch is splash resistant but not designed for swimming, showering, or submersion. Avoid exposing it to excessive moisture.
What does the reception icon (tower) on the display mean?
The tower icon indicates the watch has successfully received the atomic time signal. If it is flashing or absent, synchronization has not occurred. Move the watch to a better reception area.
How do I adjust the daylight saving time (DST) setting?
In the time zone setting menu, select DST ON (auto adjusts) or DST OFF. For some models, set to AUTO to follow regional DST rules automatically.
Can I replace the wrist strap?
Yes, the strap is replaceable. Use a spring bar tool to remove the old strap and attach a new one of the same width (typically 20 mm). Compatible straps are available from watch accessory stores.
What should I do if the display is dim or unreadable?
Try pressing the LIGHT button to activate the backlight. If the display remains dim, replace the battery as low voltage can cause poor contrast. Avoid storing the watch in direct sunlight for extended periods.
