Maintenance
The two lithium 3V batteries (CR2032) will need to be changed as needed. There
is a low battery indicator light on the receiver that tells you when you need to
change the battery. To change the batteries, remove the black rubber cover
from underneath the sensor/transmitter. The battery mount should drop down,
attached with a wire. Replace both batteries, making sure the + side of the
batteries point to the + indicated on the mount. Insert the battery mount and
replace cover, making sure it’s seated properly.
Neither the rain nor freeze sensor needs to be removed or covered during the
winter. All parts are easily replaceable if they become damaged or lost. The
spindle assembly is designed to stay with the cap. Do not pull them apart.
Follow These Simple Checks Before Replacing Your
Rain/Freeze Sensor:
System Will Not Come On At All:
A. Check to see that the rain sensor discs are dry and the switch “clicks” on
and off freely by pressing the top of the spindle.
B. Check the feature control switch to make sure it is switched to the “rain”
setting or the “rain/freeze” setting.
