Troubleshooting
If you encounter problems at any point in the installation process, or the components do not
function properly, try the Troubleshooting procedures first. If the problem is not listed or the
remedy does not resolve the problem, contact your local Toro irrigation distributor for assistance.
❑ Signal strength is weak or inconsistent.
The Wireless Rain Sensor system has a maximum operating range of 152.4m (500') LOS
(Line-of-Site). Operating range is based on optimum site conditions with no signal interference
present. But in most cases there are buildings in the way or other sources of radio signal
interference, that can reduce the signal range. Most residential and small commercial buildings
will not pose reception problems under normal conditions. However, there are some sites with
buildings or structures constructed of thick, dense walls, or contain electrical equipment that
emits high levels of radio frequency interference. If you are having difficulty obtaining good
signal strength, try the following possible solutions:
• Move the antenna away from any large metal object.
• Avoid indoor receiver locations where cellular or cordless phones have trouble with reception.
• Mount the sensor and receiver modules closer together if possible.
• If the sensor is installed directly over the receiver, move the sensor slightly to either side of
the receiver.
