4. First Time to Use

4.1 Pair the Outdoor Remote Sensor

First, pair the outdoor remote sensor with the weather station.

1. Plug in the included DC adaptor or insert 3 new "AAA" batteries (optional) into the weather station. The screen will turn on and begin searching for the sensor. During RF registration, the signal strength icon will animate until the sensor signal is received or for 5 minutes if no signal is available.
2. Slide the switch to CH1 of the outdoor sensor and insert 2 new "AAA" batteries.
3. Press the TX button on the outdoor sensor to transmit RF Signal.
4. Keep the outdoor sensor 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. Place the outdoor remote sensor near a window side to receive the atomic clock signal. Avoid placing the sensor near interference sources like electronic devices (TV, computer, microwave, radio, etc.).
7. Allow the outdoor sensor and weather station to sit together for 15 minutes to establish a strong connection.
8. Do not press any buttons for 15 minutes.
9. When the outdoor remote sensor receives the atomic clock signal, it will transmit the received atomic time to the weather station. The WWVB tower icon at the weather station will light up, indicating atomic time synchronization.
10. After 15 minutes, place the sensor in a shaded outdoor location.

Visual Description of Display during Pairing: The main unit display shows "LEARNING..." and an animating signal strength icon, indicating it is searching for the outdoor sensor.

4.2 Atomic Clock Reception

The outdoor remote sensor automatically begins searching for the WWVB signal and updates the time every day at 1:00 AM or after resetting the sensor. The updated time/date will be synchronized into the weather station, and the WWVB tower icon will light up.
