Note for the customer before use

Q: What is the DCF radio clock? Why does the screen turn off sometimes even if the power adapter is plugged especially during the night?

1. After powering on the weather station, it will start the DCF Signal search up to 7 minutes after any restart or change of batteries. Once the signal is found the Time and Date will be automatically set. During the DCF signal search mode only the “ ” and “▲” button will function, all other buttons have no function. And backlight will turn OFF during this moment even if the adapter plug in. Press and hold down the “▲” button for 2 seconds can manually start/stop the DCF signal search
2. At 1:00 / 2:00 / 3:00 am the Weather Station automatically carries out a synchronization procedure with the DCF signal to correct any deviations to the exact time, the screen will be turned off during this time. If this synchronization attempt is unsuccessful (The radio mast symbol disappears from the display), the system will automatically attempt another synchronization at the next full hour. This procedure is repeated automatically up to 5 times.

Q: Why there is “- -” display on the screen instead of outdoor data? Why do the temperature and humidity data show inconsistencies on the screen?

1. If the “- -” display is on the screen, it means the weather station and outdoor sensor are disconnected. Press and hold the “▼” button for 3 seconds to restart receive transmission data. And press the “ TX ” button on the back of the sensor to manually transmit a signal, and the connection between the weather station and the sensor will be re-established.
   2. Make sure the weather station and sensor are set in the same channel. You can press the “▼” button to switch the channel display on the screen. If you have only one sensor, we would suggest setting both the sensor and weather station display to channel 1. And make sure the symbol “ ” is disappear in the channel zone on the screen,  which means deactivating the automatic channel switching.

2. The sensor transmits data every 60 seconds to update the temperature and humidity. So if you find data is different between the weather station and the sensor, please wait for 60 seconds and let them to update. Please note the transmitting is about 60m/196feet. The displayed temperature and humidity will be more accurate after 3 hours.  Indoor and outdoor temperature error within ±1°C, indoor and outdoor humidity error within ±5%.

Q: Does the screen can constantly lit? Can the alarm clock work with battery power?

1. The weather station can be powered by an adapter(included) or batteries(not included). If the weather station is powered by the adapter, the screen will be constantly lit and the brightness can be adjusted. If the weather station is powered by batteries, press the “ ” button on the bright screen for 15 seconds and turn it off to save power. An alarm clock also can wake you up when powered by batteries only.
