How do I register?

  2. Once registered, call the Microsoft Warranty department so they can ensure the warranty is properly registered.  Please note, you will need to send them your invoice from Zengar that contains your device serial number as proof of purchase date.  Visit this page for the telephone number list:

You need to connect to the internet at least once every seven days in order to validate your license. Sessions do not need internet connectivity to run. As long as you connect to the internet prior to launching NeurOptimal® at least once a week, your license will be validated and available for sessions for the rest of that week. We advise maintaining a constant connection to the internet in order to allow your system to update both Windows 10 and NeurOptimal® regularly.

Disk cleanup is a utility that removes temporary files and clears caches that build up during the normal operation of Windows. These files can add up over time, and maintaining your system through regular cleanups will ensure you always utilize the space on your drive effectively without waste.

Follow the steps below or watch a video tutorial, here.

  1. Enter “disk cleanup” in the Cortana box, and choose Disk Cleanup.
  2. If you are currently running Windows version 1803, select all the boxes. If you are currently running Windows version 1809, select all the boxes except for the Downloads box DO NOT CHECK OFF THE DOWNLOADS BOX then click on “Clean up system files”. To confirm which version you have, type “about” in the Cortana search box and select “About your PC.
    For Windows version 1803
    For Windows version 1809
  3. Choose the “More Options” tab.
  4. In System Restore and Shadow Copies, click on “Clean up…”
  5. Click on delete.
  6. Click on OK.
  7. Click on Delete files.
  8. Allow the Disk Cleanup to finish.

Optimizing your drive once per month is a great way to keep your NeurOptimal® system happy and healthy. SSDs are very fast and efficient, but even they need to be kept in good health and regularly optimizing them will improve their performance.

Follow the steps below or watch a video tutorial here.

  1. In the Cortana search box type “Optimize”.
  2. Select “Defragment and Optimize Drives”
  3. Click on “Optimize”
  4. And you’re done!

Defragmenting your drive once per month is a great way to keep your NeurOptimal® system happy and healthy. Over time, files on your drive become fragmented, slowing down your computer as it checks multiple places on your drive for pieces. Defragmenting helps clean this up, ensuring it is running as efficiently as possible.

  1. The way that you test sensors in NO3 is to Tap and hold (right click) on the Tools icon in the VAULT.
  2. A context menu will open up and you can tap/click on zAmp Tests.
  3. You will then select Live EEG for the test and run that test AFTER placing ALL of the sensors in between your thumb and finger, one on top of the other in a single stack to “Null” them and then Click on Start Test. Press hard and the lines should converge together as they do in the image below. If not, then try again, pressing harder. If the lines still do not converge, then one or more of your sensors is bad and you will need to replace the set. Voila!

    Live EEG Test, with sensors nulled and red-blue lines converged. All good!

  • Re-pair the stylus to the Surface Pro
  • Replace stylus battery

This is normal and different from what you would expect to notice with laptops. Laptops vent their heat primarily through the keyboard, side and bottom vents. Since the Surface Pros do not have an attached keyboard (actually don’t need one) they have been designed to dissipate heat differently. In addition to this, all of the heat producing components (processors, hard drive, memory, battery, etc..) are located in the tablet itself and not under the keyboard like in laptops. This having been said, if the basic system settings have not been altered this should not be an operational problem, even though the screen and back may seem to be very warm or even hot to the touch.

One sure sign of any computer system overheating would be a complete and sudden system shutdown. This would be triggered in order to prevent any heat damage from occurring to any components.

To allow efficient cooling of your Surface Pro(s), please remember to always use them with their “kickstand” supporting them in an upright position.

  1. Press and hold the Fn and Delete keys simultaneously, for 3 seconds
  2. The blue light will start to flash and is now ready to pair.
  3. Click on Action Center
  4. Click on connect
  5. Click on Find other types of devices
  6. Click on Bluetooth
  7. Look for Moko keyboard, or it may just say Keyboard, click on pair
  • Make sure Keyboard is on and paired
  • Make sure keyboard battery is charged, using the charging cable that is provided
  • Verify that the volume is not muted or set very low on the computer.
  • It is normal for Baselines to not playback any sound and for the visualizer to be black since it responds to sound.
  • Restart your system.
  • Install all Windows updates and restart the computer.
  • Verify sound is defaulted to system speakers/headphones and not external display via control panel > sound > Playback Devices.
  • Zen times may have not loaded properly before starting a training. Improperly loaded Zen times would be indicated by 00:00 appearing in some or all of the Zen mode time fields. If you see this, click on Stop, Training, then Record to set the zen times and restart the session.
  • On all ASUS laptops provided by Zengar, the USB 3.0 port must be used when connecting the zAmp to the laptop. The location and number of USB 3.0 ports varies between ASUS laptop models, but all USB 3.0 ports are indicated with an “SS” USB symbol near the port. USB 2.0 ports on ASUS laptops will cause the NeurOptimal session to stop prematurely and unexpectedly.
  • Included with every NeurOptimal system are two 15-foot USB cables. Try using the second USB cable to see if the session still stops prematurely. If you do not have another USB cable from Zengar available, you can purchase a replacement from Zengar here: It is very important to ONLY use a USB cable provided by Zengar or the exact model recommended by Zengar or else your sessions will continue to stop prematurely.
  • Verify that system time is in 12-hour format (US English): On the Windows taskbar, look for the time and date. The time should appear in “h:mm tt” format and the date in “M/d/yyyy” format (ex. 1:29 PM and 3/8/2017). If this is not the case, right click on the time and date, then on “Adjust date/time” and then on “Change date and time formats. The settings should match this image:
  • Temporary licenses are issued to all replacement systems until the previous system is unlicensed.
  • Temporary 90-day licenses are issued to all financed systems until paid in full
  • Relicensing must be done via ZenConnect

Sometimes when starting a session in NeurOptimal Professional, the following message appears:

To get past this, click on 1. Stop 2. Training 3. Record/QR

  • For Surface Pro 4 perform a 30 second shutdown (Watch a Video Tutorial)
  • For Surface Pro 3 make sure the Bluetooth keyboard is on, paired and charged.
