5. TROUBLESHOOTING
1) The power LED flashes red:
At power up, the DLS 6700 performs a self-test. If this self-test fails, the power
LED flashes red. If this happens, consult the factory.
2) The power LED is orange:
If the DLS 6700 detects an internal error, it does a full system initialisation and
turns the power LED orange. If this happens, consult the factory.
3) The remote LED is off:
This is normal after both a power-up and a reset.
4) The remote LED is red:
The DLS 6700 received an invalid command from the computer. See Chapter 4
"REMOTE CONTROL" for more details.
5) The DLS 6700 program indicates a communication error:
• Check that no device (such as a mouse) is connected to the same serial
port as the DLS 6700.
• Check the cabling.
