Table 7. Possible troubleshooting
Trouble symptom
Neuron-Spectrum.NET software
doesn't start.
When switching on the
monitoring mode, the EEG signal
cannot be recorded.
When starting the program, the
message "Database connection
error" can appear on the screen.
Error occurs in Neuron-
Spectrum.NET software and the
operating indicator is red.
The software execution is
interrupted by USB connection
error
The exam report can't be created
or printed.
After proper setting of EEG
electrode, the impedance value is
1000 kΩ.
EEG traces recorded in one
hemisphere channel are not
displayed adequately.
EEG traces recorded in one of
the channels are not displayed
adequately.
Cause
Digital system software is not
installed or is installed incorrectly.
Digital system is connected
incorrectly.
1. The directory with patient
exam files is inaccessible.
2. The directory with patient
exam files was renamed or
replaced.
Critical error in the system
operation.
USB connector of PC does not
provide proper connection
1. The printer is not set up.
2. The printer is not connected to
PC or out of order.
Derivation cable breaks
1. Problems with reference
electrode (ear electrode during
monopolar recording with ear
electrode reference).
2. Problems with the electronic
unit.
1. The derivation cable is faulty.
2. Problems with electronic unit.
Way of Removal
1. Check whether the digital
system software is set up.
2. Reinstall digital system
software using the digital media.
1. Check whether digital system
is connected.
2. Consult the manufacturer
(Neurosoft).
1. Check the connection to local
network. Make sure that the
computer with patient file
directory is connected to local
network and switched on.
2. Restore the name and the
directory placement.
1. Exit the Neuron-Spectrum.NET
software. Disconnect the system
from USB and connect it again.
Run the program.
2. If problem still remains, consult
Neurosoft.
Reconnect the system electronic
unit to another USB connector
1. Set up the printer using
Windows control panel.
2. Check the printer connection
and its working order.
Replace the derivation cable.
1. Check the quality of electrode
setting by impedance
measurement.
2. Change places of
the reference electrode cables
(A1 and A2). If the problem is
repeated in the other hemisphere
that means the electrode is out of
operation. Replace it.
3. If the problem was not
removed, the electronic unit is
out of operation. Consult
Neurosoft.
1. Check the quality of electrode
setting by impedance
measurement.
2. Replace the electrode.
3. If the problem still remains,
address to Neurosoft.
