Step 6 : Ensure that the Green LED (Digital Transmitter) is light-up. If it does not light up, there is no established link between them. (No communication is established between the digital transmitter & receiver unit). It could be due the below possible causes: 1. The digital transmitter unit is not fully inserted into the slot of the service jig. (Note: The wireless link indicator light will be flashing if the digital transmitter unit is not fully inserted into the slot. 2. The 5V DC power supply to the service jig is not connected properly or it is connected loosely. 3. The digital transmitter or the receiver unit is not operating properly due to power supply not connected properly. (Refer to section 9.3.1 for troubleshooting procedures for the receiver module P.C.B.) Step 7 : Ensure that the audio input into the digital transmitter can be heard from the speaker at the digital receiver unit. If there is no audio output at the speaker, check and confirm the connection of speakers at the rear of the receiver unit. (Refer to section 9.3.3 for the troubleshooting procedures for checking of power Amp IC).
