LFF Household Electronics

LFF is a consumer electronics brand dedicated to improving household quality of life through intelligent and user-friendly products. Specializing in timekeeping and environmental monitoring, LFF offers a wide range of devices including digital atomic wall clocks with wireless outdoor temperature sensors, wireless weather stations, DAB/FM digital kitchen radios, and carbon dioxide (CO2) detectors.

Designed for convenience and reliability, LFF products feature auto-synchronizing atomic time, large easy-to-read displays, and precise sensors to keep users informed about their indoor and outdoor environments.

• How do I manually set the time on my LFF atomic clock?

  Press and hold the SET button for 3 seconds to enter setting mode. Use the UP/DOWN buttons to adjust values and press SET to confirm and move to the next item (Time Zone, DST, Year, Month, Day, Hour, Minute).

• How do I pair the outdoor sensor with my LFF weather station?

  Insert batteries into the main unit first, which will start the RF pairing mode. Then select a channel on the outdoor sensor and insert batteries. Keep them 5-10 feet apart until the connection is established.

• Why is the atomic clock signal (WWVB) not updating on my LFF clock?

  Place the clock away from electronic devices, large metal items, and thick walls. It typically searches for the WWVB signal automatically overnight between 1:00 AM and 5:00 AM.

• How do I contact LFF customer support?

  You can reach LFF customer support for issues with your clocks, weather stations, or air quality monitors by emailing support@lfftech.com.
