Troubleshooting Guide
First, it must be made sure that the antenna and ACU are properly connected according to page 15. If the connectors
are correct, here are the steps.
a. Disconnect the coaxial cables between the antenna and ACU, and check RX and TX coaxial cables connections with
the buzzer of multimeter. If RX and TX coaxial cables are broken, contact the manufacturer to replace.
b. Connect TX coaxial cable to the ACU, keep TX coaxial cable and antenna disconnected, and turn on the ACU power.
Use the multimeter to measure TX coaxial cable near to the antenna, and the normal voltage reading is about 48V. If
the 48V voltage is abnormal, check the ACU mainboard. If the 48V voltage is normal, connect TX coaxial cable with the
antenna.
