Maintenance
For solar models there is no required maintenance; the battery is continually
powered through the solar-trickle charge. For all other models 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 or 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.

Troubleshooting
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.
C. Toggle the manual override switch on the receiver to change status.
D. If you have a timer with built-in sensor terminals there is usually a
bypass switch located near the terminals, check that the switch is set
to "ON."
E. Check that the temperature is at least 39°F (4°C) or higher.
System will not shut off even after heavy rainfall:
A. Check wiring for correct installation (See "Operation Checks: Verify
Correct Wiring").
B. Check sensitivity setting on rain sensor, and move the cap to a more sen-
sitive setting. The rain sensor is an accurate rain gauge and can be verified by
setting up a "tube" type rain gauge in the same vicinity and making periodic
readings.
C. Check for obstructions to rainfall such as overhangs, trees, or walls.
D. Check the batteries.
E. Ensure that the solar cell is exposed to direct, unobstructed sunlight.
