DN-3000 TROUBLESHOOTING INFORMATION

The DN-3000 performs a self-test each time the unit is powered up or when the Mode Selection DIP Switch is changed. When it detects a failure, it will report the type of failure on the Status LED. All failures are reported as a flash code in which the DN-3000 will flash its Status LED yellow a designated number of times followed by a pause. The flash code will repeat itself until the unit is powered off. The possible errors that can be reported and the recommended actions are:

2 flashes followed by a pause

Random Access Memory Failure (RAM Failure)

Send the unit in for repair (Obtain RMA number first).

3 flashes followed by a pause

Firmware stored in ROM failed checksum test (ROM Failure)

Send the unit in for repair (Obtain RMA number first).

4 flashes followed by a pause

Unit Not Configured or EEPROM failure

If transferring your project file to the DN-3000 does not correct this error, send the unit in for repair (Obtain RMA number first).

5 flashes followed by a pause Invalid DIP Switch Setting

Verify that the DIP Switch is properly set to a valid operating mode (See DIP Switch Settings in this section). If the DIP Switch is properly set, send the unit in for repair (Obtain RMA number first).
