Take out the batteries and wait one minute, while covering the solar panel to drain the
voltage.
Put batteries back in and resynchronize with console by powering down and up the con-
sole with the sensor array about 3 meter away.

Best Practices for Wireless Communication
Note : To insure proper communication, mount the remote sensor(s) upright on a vertical
surface, such as a wall. Do not lay the sensor flat.
Wireless communication is susceptible to interference, distance, walls and metal barriers.
We recommend the following best practices for trouble free wireless communication.
1. Electro-Magnetic Interference (EMI). Keep the console several feet away from com-
puter monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 868 MHz devices and com-
munication is intermittent, try turning off these other devices for troubleshooting purposes.
You may need to relocate the transmitters or receivers to avoid intermittent communication.
3. Line of Sight Rating. This device is rated at 300 feet line of sight (no interference,
barriers or walls) but typically you will get 100 feet maximum under most real-world installa-
tions, which include passing through barriers or walls.
3. Metal Barriers. Radio frequency will not pass through metal barriers such as alu-
minum siding. If you have metal siding, align the remote and console through a window to
get a clear line of sight.
The following is a table of reception loss vs. the transmission medium. Each “wall” or ob-
struction decreases the transmission range by the factor shown below.
Medium RF Signal Strength Reduction
Glass (untreated) 5-15%
Plastics 10-15%
Wood 10-40%
Brick 10-40%
Concrete 40-80%
Metal 90-100%
