<br><br> <b>Specifications </b><br>1. 433 Mhz transmission frequency.<br> 2. Transmission range up to 200 ft. (range maybe shorter based on interference present).<br><br> <b>Package Contents: </b><br> 1 x remote sensor (Transmitter).<br>2 x AAA size batteries(included).<br><br> <b>NOTE: </b><br> The remote unit should NOT be placed under the direct sunlight..<br>sunlight will heat up the remote sensor which leads to higher temperature reading than the air temperature which is supposed to be measured.<br>The remote sensor must be always placed upwards so that rain won't get inside the sensor through the vent holes on the bottom of the senor which functions to let the remote sensor detect the environmental temperature and humidity more precisely and quickly.<br><br> <b>NOTE - Synchronize Remote Sensors</b><br> 1.Position the remote sensor near the base station<br> 2.Install batteries into transmitter and receiver<br> 3.The RF signal icon (located on the upper left of the base station display) will flash<br> 4.Wait for a moment or press TX button in the outdoor transmitter<br> 5.The remote sensor temperature/humidity will appear
