Battery Life
The Wireless Rain-Clik Transmitter is designed to operate 
for at least 5 years with its sealed, maintenance-free 
battery. The transmitter is available as a replacement 
part (WR-CLIK-TR). Should you need to change the 
transmitter, the receiver will have to learn the new 
transmitter address.
To Check the Status of the Battery in the 
Transmitter
1.  Press and hold the quick response spindle at the top  
of the sensor on the short stack.
2.  Within a few seconds the LED light on the bottom  
of the sensor will briey ash.
3.  Release the spindle and the LED light will ash again. If 
the LED ashes, the battery in the transmitter is good.
If you are experiencing problems with your Wireless  
Rain-Clik Sensor, follow these simple checks rst before 
assuming the unit is defective and replacing it.
