Cell phones, cordless phones, and other devices operating in the 900 MHz band can potentially cause interference with your Tracker Freedom® System. As a precaution, we recommend that you minimize their usage within the transmission range of your Tracker™ System. We have taken every precaution and tested to the highest standards to ensure accurate data transmission with your Tracker Freedom System. The main reason for linking your Tracker instruments with your software is to reduce the potential for unintentional data transfer from other devices, including other Tracker Freedom systems operating in the area. We have also incorporated state-of-the-art methods, such as frequency hopping and electronic signatures, to reduce the possibility of miscommunication.
