1.
If a specific channel is lost, press the
CH/+
button to display this channel, then Press and hold
the
CH/+
button for
3
seconds, and the remote search icon
will be constantly displayed
for up to 3 minutes. Once the signal is reacquired, the remote search icon
will turn off,
and the current values will be displayed.
2.
If new sensors are added, subtracted, or multiple sensor channels are lost, press and hold the
CH/+
button for
5
seconds (on any channel), and the remote search icon
will be
constantly displayed for up to 10 minutes. Once the signal is reacquired, the remote search
icon
will turn off, and the current values will be displayed.

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 433 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%
5.6 Adjustment or Calibration
Note:
The calibrated value can only be adjusted on the console. The remote sensor(s) always
displays the un-calibrated or measured value.
The purpose of calibration is to fine tune or correct for any sensor error associated with the devices
margin of error. The measurement can be adjusted from the console to calibrate to a known source.
Calibration is only useful if you have a known calibrated source you can compare it against, and is
