3.5 Sensor Search Mode

If any of the sensor communication is lost, dashes (--.-) will be displayed on the screen. To reacquire

the signal:

1. If a specific channel is lost, press the CHANNEL/+ button until the channel indication arrow

is pointing at the appropriate channel.

Press and hold the CHANNEL/+ button for 3 seconds, and the remote search icon

be constantly displayed for up to 10 minutes.

Once the signal is reacquired, the remote search icon

will be displayed.

2. If new sensors are added, subtracted, or multiple sensor channels are lost, press the

3.6 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.

3.7 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.

Note: 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

optional. This section discusses practices, procedures and sources for sensor calibration to reduce

manufacturing and degradation errors. Do not compare your readings obtained from sources such as

the internet, radio, television or newspapers. They are in a different location and typically update once

per hour.

The purpose of your weather station is to measure conditions of your surroundings, which vary
