There is no need to power off the power amplifier board when replacing it. Put the finger directly into the socket 16
and remove the power amplifier board. Then insert the new power amplifier board into the slot, and push it in 17
place. The red light will be on. The corresponding channel display status of the LCD is normal, and the power 18
amplifier board is in normal working condition. 19
When an amplifier module reports information “failure” on the LCD, the power amplifier board needs to be 20
replaced. 21
Note: When you do not need to replace the module, do not insert your finger into the insertion hole to avoid 22
broadcast interruption. 23
