Features:

The LCD display lights up with all the icons for 2 seconds and 3 beeps when plugged in. Then the clock begins to search for RF signals (3 minutes, for temperature readings) and WWVB signals (3 minutes, for time calibration).
Default Time: 12:00, 12-hour time format.
Date: 01 / 01 2018, Monday.
Alarm 1: 6:00 a.m. Alarm 2: 12:00 p.m.
Weather Forecast: partly sunny.

Note: Batteries are only used to save the setting of your clock. Please do not use batteries as main power supply (you will not be able to operate the weather station when it is only powered by batteries). Instead, please use the included power adapter.

Setting the Wireless Sensor

This weather station is able to pair with three wireless sensors. One of these is included in the package while you can choose to purchase two more sensors separately if necessary.
Step 1: Plug in your weather station.
Step 2: Insert the batteries in the wireless sensor and use the TX channel selector to choose the desired transmission channel (1, 2 or 3).

Note:

Please keep your weather station away from concrete walls, cellars, metal doors and equipment that generates magnetic fields such as mobile phones, televisions, etc.
Since the cover of the sensor is designed to be splash-resistant, it may take 36-48 hours for the sensor to measure temperature readings that are relatively accurate.
Please ensure the wireless range between the weather station and the sensor is within 200 feet (60 m).

Step 3: Short press the ▲ button to select the channel number that has been set on the wireless sensor in the previous step. The icon of channel number flashes in sequence of 1, 2, and 3. If signal of the sensor is not received by the weather station, the symbol “-” will appear on the
screen.

The weather station automatically receives RF signals for 3 minutes after the weather station is plugged in.
Long press the “▲” button for two seconds to re-register data for the current channel.
Reception of RF signals
1. RF reception lasts for up to 3 minutes.
2. During RF registration, the antenna icon starts to flash.
  Long press the “▲” button for two seconds to re-register data for the current channel.
3. When the RF is successfully registered, the icon is displayed.
4. If the reception fails once in the later synchronization, the icon will disappear.
5. If the reception succeeds in the later synchronization, the icon will appear again and the outdoor temperature and humidity will be updated.
6. If the weather station fails to receive RF signals more than 1 hour, it will display the latest temperature and humidity before the update.

Auto Time Calibration via WWVB Signals

After the clock has received RF signals and displayed temperature readings, it starts searching for WWVB signals for time calibration.
During the searching, the WWVB icon flashes and the screen as well as projection turns off. It takes about 3 minutes to complete the procedure and get the time set automatically. When the calibration completes, the WWVB icon changes from to .

The measurement range for indoor humidity is from 20% to 95%.
If the current temperature exceeds the maximum measurement range of the weather station, HH.H will appear on the screen. If the current temperature is lower than the minimum measurement range of the weather station, LL.L will appear on the screen.
If the current humidity exceeds the maximum measurement range of the weather station, it will display 96% on the screen. Likewise, if the current humidity is lower than the minimum measurement range, the weather station will display 19% on its screen.
The weather station will automatically update indoor temperature and humidity every 60 seconds.
When the ALARM goes off or the weather station is receiving RF signals/WWVB signals, the weather station will stop updating temperature or humidity.

Weather Forecast

The weather forecast is for the next 12 hours based on the trends of outdoor temperature and humidity.
Weather forecast: Sunny, Partly sunny, Cloudy and Rainy.
Interval of update: every 60 minutes.
The weather forecast can be more accurate if it is placed in a naturally well-ventilated space. If you place the weather station in air-conditioned rooms, the weather forecast may not be accurate.

Note: the weather station makes a weather forecast based on the tendency of outdoor temperature and humidity. If the weather station fails to receive the signals sent from the sensor, the weather forecast will be made based on the indoor temperature and humidity. If there are discrepancies between the results from your device and that of the local weather forecast service, please follow the advice from the latter one.

When the humidity is over 85%, the weather station will display the rainy icon.
When the humidity is below 35%, the weather station will display the sunny or partly sunny icon.
When humidity rises more than 5% in an hour, the weather forecast icon will change to partly sunny (from sunny), cloudy (from partly sunny) or rainy (from cloudy).
When humidity reading drops more than 5% in an hour, the weather forecast icon will change to cloudy (from rainy), partly sunny (from cloudy), or sunny (from partly sunny).
