Best Practices for Wireless Communication
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 computer
monitors and TVs.
2.
Radio Frequency Interference (RFI).
If you have other 915 MHz devices and
communication 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 installations,
which include passing through barriers or walls.
4.
Metal Barriers.
Radio frequency will not pass through metal barriers such as aluminum
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 obstruction
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%

Display Console
(1)
Connect the display console power jack to AC power adapter with the included power adapter,
as shown in Figure 4a.
(2)
Remove the battery door on the back of the console, and insert 2xAAA batteries per Figure
4b.
(3)
Wait several minutes for the remote sensor to synchronize with the display console. Make
sure the remote sensor is powered up and about 5 to 10 feet away while waiting for
synchronization. The remote search icon
will be present while searching.
Do not touch any buttons
until the remote sensor reports in, otherwise the remote sensor
search mode will be terminated and the search icon will turn off. When the remote sensor has
been received, the console will automatically switch to the normal mode, and all further
settings can be performed.
