Why are the lights on the baseband not lighting up on my Kirisun Repeater?
If the lights on the baseband of your Kirisun Repeater are not lighting up: * Check if the DC input port voltage is 13.2V. If correct, check whether DCDC (U1) input is 13.2V. If not, replace the fuse F1. * Verify if U1 output is 5V. If not, check U1 periphery or replace U1. * Check PMU (U2) or replace U2.
What does it mean if the FPGA operating LED is abnormal on Kirisun TR850 Repeater?
If the FPGA operating LED is abnormal on your Kirisun Repeater: * Check the status of the four lights (LED2, LED3, LED4, LED5) beside the baseband board FPGA (U14), and check the operating status of OMAP and FPGA. * Normally, 20 seconds after powering on, LED3 lights up, and LED2 and LED4 blink simultaneously, indicating the program is loaded successfully from NAND. * After another 40 seconds, LED3 and LED4 light up, and LED2 and LED5 blink simultaneously, indicating CPU and FPGA are started. * If the program keeps failing on loading or starting, connect to the JTAG port (J2) to connect to the OMAP simulator inspection program or reburn the program.
Why is there no voice being repeated on my Kirisun Repeater?
If there is no voice being repeated on your Kirisun Repeater: * Check Pin2 of the transmit unit connector (J17). If there's no modulation signal, check the reference voltage VREF (2.048V) of the DAC output from U29. * If the VREF voltage is abnormal, replace U29. * If VREF is normal, check DAC (U24).
