FIRST TIME TO USE

PAIR THE OUTDOOR REMOTE SENSORS

First of all, it needs to do the pairing between outdoor remote sensors and the weather station. Please follow the 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 sensor’s signal is received or for 5 minutes if no signal is available. 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 correspondingly and insert the batteries.
   Note : It needs different channels with 3 sensors in order to weather station pair properly.

3. The wireless remote sensors will transmit the signal and LED will flash during transmission.

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 of sensor pairing time, the weather station will automatically receive an atomic clock signal, and the tower icon will be flashing

7. When the weather station detects the atomic clock signal, the signal strength indication will be indicated.

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 the button for 15 minutes.

12. After 15 minutes, place the sensors in a shaded outdoor location.

3. Follow the operation “4 FIRST TIME TO USE” to start the pair the sensor.

IMPORTANT PLACEMENT GUIDELINES

• Mounting under an eave or deck rail works well.
• Mount the remote sensor on the North side where to prevent sun from causing incorrect readings
• Be sure the outdoor sensor is mounted vertically to drain moisture.
• Mount at least 6 feet in the air for a strong RF (radio frequency) signal.
• To prevent wireless interference, place units at least 3 ft (0.9 m) away from electronic devices (TV, computer, microwave, radio, etc.).
• To maximize atomic signal reception, place the weather station away from large metallic items, thick walls, metal surfaces, or other objects that may limit radio communication.
• The maximum wireless transmission range must be within 300 feet (100m) in open air, not including walls and floors.

CARE AND MAINTENANCE

• Do not mix old and new batteries.
• Do not mix Alkaline, Standard, Lithium, or Rechargeable batteries.
