5. Troubleshooting & Maintenance

1) If the units cannot be controlled by the front panel buttons, maybe the system is

online, please cut off the connection between the D-3001 and PC.

2) When the D-3001 is not able to communicate with PC by connecting the USB cable
or RS232 cable:

 Maybe the USB cable or the RS232 cable is connected loosely or have already

been broken, please connect it again or change for another one.

 Maybe the COM port number is not the same with the controlled one.

3) When the discussion unit is not able to speak:

 Check the set speech capacity and speech mode.
 Check if the chairman unit is pressing the Priority button.

4) If there are some noises inside the microphones:

 The output gain of microphone is too high.
 The spacing distance between two discussion units is too near.

5) If the POWER indicator doesn’t work or no respond to any operation, please m ake
sure the power cord connection is good.

6) If the static becomes stronger when connecting the discussion units, it probably due
to bad grounding of the D-3001, please check the grounding and make sure if the
D-3001 is connected well, otherwise it would damage the D-3001.

7) If the unit cannot be controlled through the front panel buttons or control software,
the unit may have already been broken. Please send it to the dealer for repairing.
