  If your Rain Bird Accessories device indicates a low battery, replace it. Remove the battery cassette from the sensor, then remove the battery from the cassette. Insert a new battery, using the label on the battery cassette to properly orient the battery. Then, insert the battery cassette back into the sensor. The sensor LED will blink once to indicate the sensor is powered up. Under normal operation, the battery should last for four or more years.
