Troubleshooting

Introduction

This chapter provides troubleshooting information and

procedures for VIASYS Neurocare’s line of XP-based

neurodiagnostic instruments - Endeavor CR,

VikingQuest and VikingSelect.

The modular construction of these instruments and the

USB/FireWire Diagnostic packages included with these

systems make troubleshooting easy.

The first part of this chapter describes the use of the

USB/FireWire Diagnostics for testing the VIASYS-

unique hardware modules.

Next, is a section on Symptoms & Solutions that

addresses a variety of potential hardware, software,

environmental and operational issues.

Finally, we provide a list of Error Messages that you

might encounter and suggestions for resolving these

errors.

Try this First

Historically, the most common problems fall under two

categories: cabling problems and operational problems.

To resolve problems quickly and efficiently, we

recommend the following general procedures.

Hardware/Cabling Problems

1. Verify that all system cables are properly connected

and securely attached. If necessary, refer to the

cabling diagrams at the beginning of Chapter 3.

2. Verify the system is plugged directly into a working

hospital grade receptacle. Systems should not be

plugged into an extension cord or an unapproved

(non-medical grade) power strip.

3. Verify that the power On/Off switch on the isolated

power supply or medical grade power strip is

turned ON. Verify that the indicator light on the

power supply or power strip switch is illuminated.

If necessary, check the fuses or circuit breaker.

4. Verify that the indicator lights are illuminated on

the base unit, computer, and external modules.

5. Run the USB/FireWire Diagnostics to verify that

all VIASYS-unique modules are functioning

correctly.

6. Check the Device Manager to look for clues to the

source of a problem. Refer to Chapter 4: Software

Description for detailed instructions on using the

Device Manager.

Software/Application Problems

1. For lock up problems during system operation,

press and hold the <Ctrl>-<Alt>-<Delete> keys

simultaneously to invoke the Windows Security

screen, then click on Shut Down to reboot the

system.

2. If the problem recurs, reboot and click on

Start>Help and Support>Fixing a problem for

guided troubleshooting assistance related to the

Windows XP operating system and computer

platform.

3. Verify that the screen savers and power

management features are turned off.

4. Verify that no “unauthorized” third-party software

packages have been added to the system -

especially programs that may load on start-up and

run in the background.

5. From each drive’s Properties screen/Tools tab, run

the Error Checking utility to verify the integrity of

the system’s file/directory structure.

6. From each drive’s Properties screen/General tab,

verify at least 20% free space. Run the Disk

Cleaner utility to remove temporary files from the

system and conserve disk space.

7. Check the error logs to look for clues to the source

of a problem. Refer to Chapter 4: Software

Description for detailed instructions on checking

the error logs.

Operational Problems

Consult your system User’s Guide or On-Line Help for

assistance with running the application.
