Summary
Below are lists of things that can cause excessively high or low readings with the MyoVision 8000 or the
3G WireFree system. You should also check the Basic Troubleshooting document for more information.
Equipment Check – Electrodes
Electrodes should be changed every 150 usages or every three months.
Take a look at your electrodes. Would you describe them as dark gray with a matte finish? Or would you
describe them as silver and shiny? If they are silver and shiny, they need to be replaced.
If you replaced your electrodes and the problem still exists, verify the last time you purchased
electrodes from MyoVision. Electrodes have a shelf life of at least two years if stored in appropriate
conditions. You may need to order new ones.
If you ordered electrodes less than two years ago and you are still getting inaccurate readings, you may
still need to order new electrodes.
After you have replaced your electrodes, try scanning again.
Equipment Check – Kinks in Wires
Look at the cables (this includes the cables connecting your devices to the box, the box to the wall, and
the box to the computer). Are there visible kinks? Are there exposed ends?
Run your fingers down the cable to feel for any other bends or kinks in the cable.
Your cables will not last indefinitely. If you feel or see kinks in the cable, you will need to order new
ones. You especially need new cables if there are exposed wires.
After you have replaced your wires, try scanning again.

Equipment Check – Build up of QuickScan fluid
Check the base around the electrodes. Is there a build-up of white deposits?
If you are seeing white deposits around the base of the electrodes, use cotton swabs or a cloth with
isopropyl alcohol to remove them.
To prevent build-up, dab the electrode posts with alcohol after each scan. Do not rub the electrodes
with the alcohol pad as alcohol will wear out the electrodes prematurely. Twice a month, remove the
electrodes and clean the body of the scanners with a cotton swab dipped in rubbing alcohol, paying
particular attention to the area around the electrodes.
QuickScan Pads Review
One of the most common causes for inaccurate readings is incorrect usage of QuickScan Pads.
You should always use QuickScan pads. QuickScan pads are concentrated conductive fluid necessary for
the scans to be accurate.
Simple rubbing alcohol is not a substitute for QuickScan pads. Rubbing alcohol is only to be used for
cleaning the scanner and wiping down the patient’s skin. Using rubbing alcohol instead of QuickScan
pads could potentially damage the device and will certainly wear out the electrodes faster.
Best Practice for QuickScan Pads
1. Take a pad out of the QuickScan pad jar and place it on top of the lid.
2. Press the electrodes of the scanner to the pad with intent, but not roughly.
3. Find the section you are scanning, press electrodes to skin, and begin scan.
4. Repeat steps 2 and 3 for each vertebra.
You should use QuickScan pads between every skin contact. Example: Dab electrodes on a pad, then
scan for C2 reading. Then touch electrodes to QuickScan pad and perform C4 reading. Etc.
After you have assessed your use of the QuickScan pads, implement the necessary changes and perform
your scans again.
Never place the probe inside the jar, as this will get the liquid on the probe, potentially damaging it. In
addition, do not rub QuickScan liquid onto the patient’s skin using the pad.

Check the “STATIC” setting on the M8000 box
Check the “STATIC” setting on the M8000 box
Look at the lights on the M8000 box. One will be labeled power. The other light should be next to the
word “STATIC” spelled vertically.
If the light is not on next to the word “STATIC,” check to see if it’s on next to the word “DYNAMIC” (also
spelled vertically). If the light is on next to the word “DYNAMIC,” then you will need to toggle the switch
in the middle of the box so that the light changes to “STATIC.”
Note: Sometimes, the light in the box can wear out, meaning that you may not see a light next to the
appropriate signifier. Unfortunately there is no way to remedy this as the M8000 box is no longer
manufactured.
Try your scans again.
Skin Preparation Review
For more process review, consult your MyoVision User’s Guide.
Wipe the skin with alcohol along the paraspinals. Begin with the cervical left side, and rub down the
spine. Repeat this for the right side. A simple wipe down the skin once or twice is usually sufficient. Dry
the skin dry with a paper towel before testing to make certain that the skin is dry prior to testing.
Check for updates to your computer
You should be updating your computer regularly. Many times these errors occur because the updates have not been done for some time. Windows sends updates to your computer every second Tuesday of the month. These are important for the continued functionality of your machine.
1. Go to Control Panel to locate Windows Update.
2. In control panel, change your view so that you can see many smaller icons.
3. Locate program, Windows Update
Alternatively, you could also search for Windows Update.
4. Click the "Check for Updates" button.
5. Install all Important Updates.
6. Restart your computer.
7. Repeat steps 1 - 6 until there are no more important updates to install.
Depending on how long it’s been since you’ve updated your computer, how fast your computer is, and how strong the internet connection, this process can take anywhere from 2 hours to 2 days.
Once your computer has been updated, try your scans again.
