2AQBD-60234weather station

Operation instruction Model number: Main Features: YT60234 Operating instructions: Once your weather station powers on, it should automatically search for and connect to the wireless sensors. If the weather station does not connect within the first 5 minutes, refer to the following section, “RE-PAIRING SENSOR”. You will see the icon of an antenna scrolling in the temperature and humidity (outdoor) section of the display. Once the pairing process completes, the antenna icon will appear solid (not flashing), and the readings for outdoor temperature and humidity, wind speed, wind direction, UV, light intensity, and rainfall will appear in their designated sections of the LCD display. If the connection fails or the weather station is reset, then press and hold the【CHANNEL】button over 2 seconds to enter pairing mode, and the weather station will re-register all the sensors that have already been registered to it before, (i.e. the weather station will not lose the connection of the sensors that you’d paired up before.) Press and hold 【BARO/-/ 】 button over 3 seconds, the weather station LCD display will show the letter “AP” that it has entered Access Point (AP) mode. At this time it will be ready for the Wi-Fi settings to be adjusted. Use your smartphone, tablet, or computer to connect to the weather station via Wi-Fi by following these steps: 1.) On PC, open your Wi-Fi network settings. On Android™ or iOS devices, go to settings menu and then select Connections/WI-FI to open the network settings. 2.) Locate the weather station SSID from the list. It should appear as WWS-XXXXXX (where all the X’s are integers) in the list. Tap on the SSID to connect. This step will take several seconds. 3.) Once you are connected to the weather station, open up your internet or mobile web browser, and enter the following address into the address bar: http://192.168.1.1 to access the weather station web interface. (Make sure to include the http:// or else the web browser may interpret the address as a search query). We recommend using the latest version of reputable web browsers. 4.) Enter the following information into the web-interface. Make sure all of the information is entered prior to selecting Save. If you choose not to upload Wunder- ground.com, or upload weathercloud.net, leave the check boxes unchecked. 5.) If all of the information you entered is correct, press “Apply” to confirm. If it does not, check your web interface information again. When the weather station successfully connects to your Wi-Fi router, the Wi-Fi signal will appear on the LCD display. If the Wi-Fi signal is not stable or the weather station is trying to connect to the router, the icon will flash. If the icon disappeared, it means the weather station is not connected to the Wi-Fi router. Outdoor temperature/humidity reading, weather index Wind direction & speed Indoor temperature/humidity reading Weather forecast Time & date, moon phase, Weekday Light intensity UV index Rain Barometer After the weather station has connected to the internet, it will attempt to connect to the internet time server to obtain the UTC time. Once the connection succeeds and the weather station’s time has updated. The icon “SYNC” will appear on the LCD. In Normal time display, press and hold 【SET】over 2 seconds to enter time setting mode. Press and release 【WIND/+】 and 【BARO/-/ 】 to adjust the values. Hold 【WIND/+】 and 【BARO/- / 】 over 2 seconds to adjust the values rapidly. Press and release 【SET】to confirm and move to the next item. To exit the setting mode any time, press 【 LIGHT/SNOOZE】button. In normal time display, press 【SET】button to switch display alarm time (alarm time mode). In alarm time display, press and hold 【SET】button over 2 seconds to enter alarm setting mode. Hour of alarm starts to flash. Press 【WIND/+】button or 【BARO/-/ 】 button to set required alarm hours. Press 【SET】button to select minute of Alarm. Minute of alarm starts to flash. Press 【WIND/+】 button or 【BARO/-/ 】 button to set required alarm minutes. In alarm time display, press 【TEMP/ 】button to select the Alarm on or off. If the alarm is on, its corresponding alarm icon will be shown on the display. When the alarm is ringing, press any buttons except 【 LIGHT/SNOOZE】button to stop the alarm signal. It is not necessary to reactivate the alarm. It will ring again this time next day. When the alarm rings, press 【 LIGHT/SNOOZE】button to pause the alarm. The snooze indicator icon keep flashing. The alarm will resume after 5 minutes. In normal mode, press 【BARO/-/ 】 button switch between absolute and relative pressure. In normal display mode, press 【WIND/+】button to switch between current average wind speed, gust wind speed and wind direction. In normal display mode, press 【RAIN】button to switch between Rain Rate, Rain Event, Rain Hourly ,Rain Daily, Rain Weekly, Rain Monthly and Rain Total. In normal display mode, press and hold 【RAIN】button over 2 seconds to reset the rain record. When reading the Weather Index display, you can press 【TEMP/ 】 button to cycle through different weather indexes in the following order: Feels Like > Heat Index > Wind Chill In normal display mode, press 【MAX/MIN】button switching between maximum and minimum value. To clear the max value, press and hold 【MAX/MIN】button over 2 seconds while max values are displayed. To clear the min value, press and hold 【MAX/MIN】button over 2 seconds while min values are displayed. In normal display mode, press and hold 【ALERT】button over 2 seconds to enter the alert setting mode. Press 【WIND/+】button and 【BARO/-/ 】button to adjust the value up or down, then press 【TEMP/ 】button to turn on/off the alert. Press 【ALERT】button to confirm and jump to next setting. The icon will display when the alert is on. Manufacturer: FUJIAN YOUTONG INDUSTRIES CO.,LTD.
