Frequently Asked Questions - WT-991 BL LA CROSSE TECHNOLOGY
How does the atomic time synchronization work?
The La Crosse WT-991 BL receives the WWVB time signal from Fort Collins, Colorado, and automatically sets the time to the atomic clock standard. It updates daily to maintain accuracy.
How do I set the time manually if the atomic signal is not available?
If you are outside the signal range or the signal is weak, you can set the time manually. Press the appropriate button to adjust the hour, minute, and time zone. The watch will still attempt to synchronize when the signal returns.
What type of battery does the WT-991 BL use and how long does it last?
The watch uses a CR2025 lithium coin cell battery. Depending on usage, the battery typically lasts about two years before replacement is needed.
Is the watch water-resistant? Can I swim with it?
The WT-991 BL has a water resistance rating of 3 ATM / 30 meters, meaning it can withstand splashes and brief immersion. It is not suitable for swimming, snorkeling, or diving.
Can I set the watch to 12-hour or 24-hour format?
Yes, the time format is user-selectable. In timekeeping mode, you can toggle between 12-hour and 24-hour display to match your preference.
How do I switch between time zones?
The watch includes the four US time zones: Eastern, Central, Mountain, and Pacific. In settings mode, select your local time zone so the atomic signal adjusts the hour correctly.
Does the watch have a backlight for night use?
Yes, the watch features an electroluminescent backlight. Press the light button to illuminate the display for a few seconds in low-light conditions.
What should I do if the display becomes faint or blank?
A faint or blank display usually indicates a low battery. Replace the CR2025 battery with a new one, ensuring the polarity is correct. If the problem persists, contact the manufacturer.
How should I clean and maintain my wristwatch?
Clean the case and strap with a soft, dry cloth. Do not use chemical solvents, abrasive cleaners, or immerse the watch in water. Avoid exposing it to extreme temperatures.
Are spare parts available for the WT-991 BL?
Yes, the battery and other components can be replaced. Spare parts and repair services are available through La Crosse Technology customer support or authorized service centers.
