Solution Steps:

1. Try connecting the device to a different USB port (preferably a direct port on the computer, not a USB hub)
2. Check the USB cable for damage and replace if necessary
3. Restart your computer with the device disconnected, then reconnect after Windows has fully loaded
4. Update or reinstall USB drivers:
   • Open Device Manager (right-click Start menu and select “Device Manager”)

Solution Steps:

1. Ensure the encryption lock (USB key) is firmly inserted into a working USB port
2. Try a different USB port, preferably USB 2.0 for older encryption locks
3. Close and restart the Quantum Analyzer Software with the encryption lock already inserted
4. Check for physical damage to the encryption lock
5. Verify that the encryption lock LED light (if present) illuminates when connected
6. Clean the USB connector gently with compressed air or a soft cloth

Solution Steps:

1. Ensure the client is holding the sensor correctly:
   • The sensor should be held firmly but not squeezed
   • The client’s hand should be clean and dry
   • Remove any metallic items (watches, jewelry) from the client’s hands and wrists
2. Check the sensor cable for damage or loose connections
3. Verify that the client is sitting still and relaxed during the test
4. Ensure no mobile phones or other electronic devices are within 1 meter of the analyzer during testing
5. Clean the sensor contacts with a slightly damp cloth and allow to dry completely

Solution Steps:

1. Ensure the testing environment is free from electromagnetic interference:
   • Move away from large electronic equipment
   • Turn off nearby mobile phones
   • Ensure the analyzer is not placed on metal surfaces
2. Check that the client is properly hydrated (dehydration can reduce signal strength)
3. Verify that the client is not wearing synthetic gloves or has excessive hand lotion
4. Try slightly moistening the client’s palm with a small amount of water
5. Restart the device and software to reset the sensor calibration

Solution Steps:

1. Wait at least 2-3 minutes as some complex analyses require additional processing time
2. If the software remains frozen, force close the application:
   • Press Ctrl+Alt+Delete and select “Task Manager”
   • Find the Quantum Analyzer Software in the list of processes
   • Select it and click “End Task”
3. Restart your computer completely
4. Launch the software with administrative privileges (right-click and select “Run as Administrator”)
5. Reduce other running applications to free up system resources

Solution Steps:

1. Verify you have sufficient disk space (at least 500MB free) on the drive where reports are saved

   • Right-click on the destination folder and select “Properties”
   • Go to the “Security” tab and verify your user account has “Write” permissions
3. Try saving to a different location, such as the Desktop
4. Check if your antivirus software is blocking the report generation

   • Go to Control Panel > Programs > Programs and Features
   • Find any PDF-related components and select “Repair”
   • Alternatively, install a free PDF reader like Adobe Acrobat Reader

Preventive Maintenance Checklist:

• Keep your Quantum Analyzer Software updated to the latest version
