3. Wireless Sensor Installation Outdoor Installation Use four screws to fix the base of the outdoor sensor on a flat surface.
4. Console Operation Note: The console has two buttons for easy operation: 【 °C/°F 】 button (on the left), and 【MAX】button (on the right). 4.1 °C/°F Short press【°C/°F】button: switch between display of temperature unit: °C/°F Press and hold the 【 ° C/ ° F 】 button for 2 seconds: switch between display of the 24H average value of the PM2.5 concentration and AQI. 4.2 MAX Short press the【MAX】button: switch between display of the 1h MAX / 24h MAX / MAX(since last reset) value of the PM2.
5. Sensor Resynchronization When the remote sensor lost reception, holding the °C/°F and MAX button for 5s, will register new outdoor for 12 minutes. While in the search mode, the reception search icon flash. You can also re-sync the two units by removing all the batteries and then wait for several minutes. Then install the batteries again to register faster. 6. Best Practices for Wireless Communication Note: To insure proper communication, place the remote sensor on a flat surface.
