Frequently Asked Questions:

Q1: Why does the screen turn off after powering on the weather station? And sometimes during the night? What is RCC / WWVB? A: After powering on the weather station, it will soon activate the RCC function (Radio-controlled automatic time-calibration, abbr. RCC / WWVB). During the process, the display screen will automatically turn off to reduce other interference. After the process(in 7 minutes), the screen will light up again. Every night, at 1:00am, 2:00am, 3:00am, it will start RCC. If the reception of the RCC signal fails due to signal interference or a weak signal, it will start again at 4:00 am. If fails again, it will start again at 5:00 am. After 5:00 am, whether successful or not, it will not automatically start RCC. During the RCC process (in 7 minutes), if you want to light up the screen, please press “SNOOZE”, at the same time RCC will continue. If you want to stop RCC, please press “-“, RCC will stop and the screen will light up. If you want to activate RCC manually, please hold “-” for 2-3 seconds, the station will start RCC.
Q2: Why does the weather station not display the outdoor temperature? Why is there a horizontal line on the screen? Why do the temperature and humidity data on the screen show inconsistencies? A: In order to ensure that the device can receive signals quickly, please follow the steps below: (1)Power on the weather station first. (2)Then power on the sensor. (3)Confirm that the clock and the sensor are in the same channel. (4)After establishing a connection, the sensor transmits data every 60 seconds to update the temperature and humidity data. (5)If the connection failed, please hold”CH”for 2-3 seconds to clean up the data and restart to receive the data. And press the button “TX” on the back of the sensor to transmit a signal. The connection will be re-established. If there is a horizontal line on the screen (not displaying the temperature and the humidity), please ensure your station and the sensor are in the same channel. Please note that the transmitting distance is within about 60m/196feet. The displayed temperature and humidity will be more accurate after 3 hours. If there is some error, please wait about 3 hours. Indoor and outdoor temperature error within ±1, indoor and outdoor humidity error within ±5%.
Q3. Does it run on batteries during a power outage so that the alarm clock will still wake you up? AYes, the alarm clock will wake you up also when powered by batteries. The weather station can be used with a power adapter(in the package) or batteries(not included in the package). If powered by the adapter, the screen will be brighter and stay always bright. If powered by batteries, the screen will be darker and it will be off after about 15 seconds to save battery power.

ATTENTION:

  • If the weather station is powered by batteries, the brightness of the screen will be in low brightness and the brightness cannot be adjusted. The screen of the weather station will turn off after about 15 seconds to save power.
  • If you want the screen to be constantly lit and bright, or if you want to adjust it to your preferred brightness, please use the adapter to power it (cable adapter in the package). Note: batteries are no  included in the package.
