Parts List
2.2 Display Console Set Up
- Move the remote thermometer(s) about 5 to 10′ away from the display console (if the sensor is too close, it may not be received by the display console). If you have more than one probe thermometer, make sure they are all powered up and transmitting on different channels.
- Remove the battery door on the back of the display, as shown in Figure 1. Insert four AAA (alkaline or lithium, avoid rechargeable) batteries in the back of the display console.
All of the LCD segments will light up for a few seconds to verify all segments are operating properly. - Replace the battery door, and fold out the desk stand and place the console in the upright position.
The console will instantly display indoor temperature as designated by the icon. The remote temperature probes will update on the display within a few minutes on the appropriate channel.
While in the search mode, the remote search icon 
will be constantly displayed for each sensor.
If you have more than two remote sensors (additional channels 3-8 are supported), the display will automatically toggle between sensors until all sensors have reported in.
Do not touch any buttons until all of the remote sensors has reported in, or the radio search icon is no longer visible, otherwise the remote sensor search mode will be terminated. When the remote sensor temperature has been received, the console will automatically switch to the normal mode, and all further settings can be performed.
If a remote does not update, please reference the troubleshooting guide in Section 6.

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.
- Electro-Magnetic Interference (EMI). Keep the console several feet away from computer monitors and TVs.
- 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.
- 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.
- 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 significantly from location to location.
Prior to entering the calibration mode, press the CHANNEL/+ button until the channel indication arrow is pointing at the appropriate channel.
To enter the temperature calibration mode, press and hold the ALARM/ADJUST and CHANNEL/+ buttons at the same time for 5 seconds and the temperature value will begin flashing. Press the CHANNEL/+ button to increase the temperature and the CLEAR/- button to decrease the temperature reading in 0.1° increments. To rapidly increase (or decrease) the temperature reading, press and hold the CHANNEL/+ or CLEAR/- button.
To return the temperature to the actual or uncalibrated measurement, press the ALARM/ADJUST button.
Once the displayed temperature equals the calibrated source, press and hold the ALARM/ADJUST button for three seconds, or wait 15 seconds for timeout, and the temperature value will stop flashing.
Discussion: Temperature errors can occur when a sensor is placed too close to a heat source (such as a building structure, the ground or trees).
To calibrate temperature, we recommend a mercury or red spirit (fluid) thermometer. Bi-metal (dial) and other digital thermometers are not a good source and have their own margin of error. Using a local weather station in your area is also a poor source due to changes in location, timing (airport weather stations are only updated once per hour) and possible calibration errors (many official weather stations are not properly installed and calibrated).
Place the sensor in a controlled environment next to the fluid thermometer, and allow the sensor to stabilize for 48 hours. Compare this temperature to the fluid thermometer and adjust the console to match the fluid thermometer.
