Digital Conference System (D-3002)
6. 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 control unit and PC.
2)
When the control unit is not able to communicate with PC by connecting the twisted
pair or RS232 cable:
Maybe the twisted 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)
If the
POWER
indicator doesn’t work or no respond to any operation, please make
sure the power cord connection is good.
4)
If the static becomes stronger when connecting the discussion units, it probably due
to bad grounding of the control unit, please check the grounding and make sure if
the control unit is connected well, otherwise it would damage the control unit.
5)
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.
