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:
Ma ybe the USB cable or the RS232 cable is connected loosely or have already
been broken, please connect it again or change for another one.
Ma ybe 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
POW ER
indicator doesn
’t work or no respond to any operation, please make
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.
