4 FIRST TIME TO USE
First of all, it needs to do the pairing between outdoor remote sensors and
weather station. Please follow below procedure to pair the sensors.
1). Plug the included AC-AC adaptor into the weather station. (optional) insert 2
new “AAA”alkaline batteries for backup.
The screen is turned on. It starts to search sensors and register the received
sensors. During RF pairing, the signal strength icon will animate until the
sensors signal is received or for 5 minutes if no signal available.

6
12
Note: If no sensors is paired, you can pair the sensors again manually by
pressing and holding the 【 CHANNEL】 key over 2 seconds. Please refer to
“14 SEARCH FOR OUTDOOR SENSORS”.
2). Slide the switch to CH1/CH2/CH3 of the outdoor sensors correspodingly and
insert the batteries.
Note: It needs different channels with 3 sensors in order to weather station
pairing properly.
3). The wireless remote sensors will transmit the signal and LED will flash during
transmission.

7
4). Keep the outdoor sensors 5-10 feet from the weather station.
5). When the RF connection is established, the temperature and humidity
readings will appear on the station.
6). After 5 minutes sensors pairing time, the weather station will automatically
receive atomic clock signal, the tower icon will be flashing.
7). When the weather station detects the atomic clock signal, the signal strength
indication will be indicated.

You can receive the atomic clock signal manually. In Normal time display, press
and hold the 【 Down/°C/°F/RCC】over 2 seconds to receive the atomic
clock signal manually.
The tower icon is flashing and will start atomic clock reception.
When the atomic clock signal is received successfully, the time and date will be
updated.

8). Put the weather station away from interference, such as electronic devices
(TV, computer, microwave, radio, etc.)
9). When the atomic clock signal is received successfully , the time and date will
be updated.
10). Allow the outdoor sensors and weather to sit together for 15 minutes to
establish a strong connection.
11). Do not press button for 15 minutes.
12). After 15 minutes, place the sensors in a shaded outdoor location.
• The weather station automatically begins search WWVB signal and update the
time every day at 1:00am，2:00am，3:00am，4:00am，5:00am.
• The Atomic Time tower icon will flash while searching and will be solid when
it has connected.
