ON indicates disable failsafe Servos will remain on the last position after losing signal OFF indicates enable failsafe After losing signal the receiver will read out servo position data which is previously stored in the receiver Note SW2 can only take effect when it is set before the transmitter and receiver power on SW3 is designed for selecting input signal ON indicates DATA1 and DATA2 can only input PPM signal UHF transmitter is used for directly connecting to the remote control equipment OFF indicates DATA1 and DATA2 can only input digital signal It is used to connect the signal acquisition system Note When using the PPM signal please select low power mode in order to avoid distortion of the PPM signal and the crash of remote control equipment SW3 can only take effect when it is set before the transmitter power on SW4 is designed for debug mode ON indicates for enable the debug mode Then the RF power amplifier will turn off and the RF output will be very weak This mode is used for checking whether the transmitting and receiving communication is normal OFF indicates for the normal mode Note SW4 can only take effect when it is set before the transmitter power on SW5 and SW6 are designed for select the output frequency The frequency table is as follow SWS is OFF amp SW6 is OFF 435Mhz amateur bands SWS is OFF amp SW6 is ON 445Mhz amateur bands SWS is ON amp SW6 is2. If the distance is close or the signal is strong but the RX blinks irregularly this means the current frequency band is very dirty Generally the 433ISM band will be very dirty because all industrial devices use this frequency band If the test fails you can change to another frequency band Step two after the receiver is installed bind it after all airborne devices are started This binding is intended to exclude the EMI interference from airborne devices Quality certified products generally have good electromagnetic compatibility but the others are likely to have electromagnetic leakage The noise peak value in the UHF frequency components may be not small and even the noise as weak as 100dBm may reduce sensitivity of the receiver seriously After the binding is completed the receiver will display the highest value of EMI in the current band LED1 LEDS are off indicating the input signal is less than 115dBm LED1 is lit indicating the input signal is from 115 dBm to 109 dBm LED2 is lit indicating the input signal is from 109 dBm to 103 dBm LED3 is lit indicating the input signal is from 103 dBm to 97 dBm LED4 is lit indicating the input signal is from 97dBm to 85 dBm LED4 is lit indicating the input signal exceeds 85 dBm Under normal circumstances the LED2 will light In excellent case only LED1 lights If LED3 is lit this means that you need to adjust the position of airborne equipment Step three adjust the posit
