Make sure the product is installed and calibrated correctly, failure to do so may result in serious injury. Keep the RF's antenna at least 1cm away from conductive materials such as carbon or metal. In order to ensure good signal quality, do not hold the RF antenna during use. Do not power on the receiver during the setup process to prevent loss of control. Make sure to remain within range to prevent loss of control. It is recommended that an external power supply is used in order to make sure that the RF module is getting enough power to function correctly.
