TRANSMITTER BOX-BATTERY INSTALLATIONThe solar panel on transmitter box is an energy saving feature, which is an environmentally friendly way to provide power to the sensors and prolongs battery life. It can entirely provide power to the supplied rechargeable battery. Sensors can operate entirely on the rechargeable battery power. Locate the transmitter box under direct sunlight for power supplying by the solar panel.The rechargeable battery from factory is not with full battery for long time use and it probably becomes low battery during the shipping. We recommend you to charge it for several hours by the connected solar panel. You can also purchase a power adapter separately for directly providing power to the transmitter box. The output voltage of the power adapter is 3V. Route the adapter cable through the cable slot.Please check the solar panel connection. If it is not firmly plugged, please re-connect the solar panel: Plug the end of color-corded connector into corresponding socket in the transmitter box as shown below and place the wires neatly inside the box. To install the rechargeable battery: Insert the battery into the battery compartment, matching the polarity +/-. polarity + CHANNEL SETTINGYour weather station system can expand with up to 8 sets of thermometer & humidity sensors, and one of each of wind and rain sensors, which share one main unit to display the weather readings. You can number each transmitter box with an independent channel ID (1-8) by sliding the switches. Please follow the below chart to adjust the sliding switches of SW1: NOTE The below 0 in the chart represents off and 1 represents on.
