How can I synchronize my ThermoPro TP65 remote sensor with the base station?

[MacJosephine]

To sync your ThermoPro TP65 Wireless Humidity and Temperature Monitor remote sensor with the base station, follow these steps: First, place the remote sensor close to the base station. Next, insert batteries into the remote sensor. After installing batteries in the base station, the RF signal icon on the base station display will blink for three minutes, signifying synchronization mode. If the RF signal icon stops flashing before you complete the process, press and hold the CHANNEL/SYNC button on the base station for three to four seconds until the RF signal icon starts flashing again. Then, either wait a short time or press the TX or RESET button located inside the remote sensor's battery compartment. When the remote sensor's temperature and humidity readings appear on the base station display, the synchronization is complete. Remember to repeat this synchronization process whenever you replace batteries or if the base station and remote sensor lose connection. You can register up to three remote sensors with one base station. If you have extra sensors, repeat the steps above to pair and connect.
