PASS Terms of Service

Who can join?
Users of the current version of NeurOptimal® Professional Edition are eligible for membership (users of earlier versions must upgrade prior to seeking membership).

Which systems are supported under the PASS technical support umbrella?

  • Your NeurOptimal® installation must be on a supported system, approved by the technical team, via MouseCall.
  • Systems less than 3 years old
  • Membership is per license-encoder-computer system configuration. The owner of the license is generally the member

The owner may allocate a representative to stand in their stead.

Multiple Systems: Owners of multiple software licenses can purchase additional memberships at half price, assuming that the same person is representing all licenses.

NeurOptimal® Representatives’ PASS memberships are for their personally owned systems. Representatives’ users must purchase their own membership for their systems to be supported.

Membership Refusal/Termination:

  • Zengar Institute Inc. always reserves the right to offer membership and to refuse membership entirely at its discretion, at any time.
  • Should Zengar Institute Inc. (or its representatives) elect to terminate a membership, the user will be reimbursed for the time remaining less their membership months calculated at the monthly rate. So, if the individual pre-paid for the year and were asked to leave PASS after 4 months, their reimbursement would be the annual fee minus (monthly fee x4).

Privacy: The contents of PASS are private, and this privacy for all members is taken very seriously. Information and resources enjoyed as a result of PASS membership are for the member’s own use only. While we certainly understand the process of sharing information with an interested significant other, please understand that under no circumstances can these resources or information contained therein be circulated in any manner, shape or form. PASS forums are confidential. Please do not post any PASS materials on any website.

Free Technical Support: If you have just received a new bundle you are already a PASS member and your system has already been accepted under the PASS umbrella. For new PASS members with systems older than 6 months, your system will be cleaned up and validated over an Initial MouseCall (billable after 30 mins), by our technical support staff and deemed supportable – or not – under the PASS umbrella. Generally, systems configured by Zengar fewer than three years old are accepted. Systems that are not accepted may still qualify for limited PASS support. More details will be provided to you by our technical and administrative staff should you fall into this category. Zengar has the right to accept or deny technical system support under PASS upon inspection of the system via the initial MouseCall. Hardware issues (excluding zAmp) must be dealt with directly with the manufacturer. We can try to diagnose hardware issues, but in some cases a local technician may be required or the computer or encoder may need sending to the manufacturer for diagnosis & repair. Technical Support is offered via the PASS forum and MouseCalls only. We do not offer telephone support.

In no case can we help with Internet connectivity or speed issues, nor do we support Macintosh or any OS other than W8 & W10 on systems having originated from Zengar.

Under no circumstance is Zengar to be held accountable for loss of time, income or clientele due to technical support issues. If you are a trainer by profession we strongly advise incorporating redundant systems into your practice and obtaining business interruption insurance from a third party vendor.

Please refrain from having any technician other than a Zengar technician work on your system. MouseCalls incurred after an outside technician has worked on your system may deem support time billable.

Programs not included with the NeurOptimal® system as configured by Zengar should never be installed on your system. These “other” programs may interfere with and inhibit NeurOptimal® performance and is therefore not recommended. We also do require that you keep an up to date version of our only approved Norton product installed and active on the system at all times. Please update Norton’s as often as prompted. Mousecall time spent uninstalling unapproved or extra software is always billable, so please do your best to keep your system clean.


Annual membership: Upon signing up at the monthly rate, you are committing to a 12 month contract. Once those 12 months are up the membership will continue, but you can cancel at anytime. Only should you cancel and then re-join will you need to complete the initial 12 month commitment again. You can prepay for a year at a discounted rate or you can pay on a monthly basis at the regular fee. To pay on a monthly basis you need to provide customer care with a credit card that is valid through the duration of your membership. We’re sorry, no credits are issued for cancelled memberships and payment in full is required for any outstanding balance.High Speed Internet: PASS members must avail themselves of high-speed (cable or DSL) internet access. Our ability to provide you with remote technical support depends on the quality of your internet connection. You also need high-speed internet to reasonably perform the necessary maintenance tasks on a regular basis. Please do not attempt a mousecall from a dial-up connection. Also, please login to MouseCalls using a wired connection as opposed to wireless. Wireless connections can drop which would require you to log back in each time.

System Specs: To have your system covered under PASS, your system must be “up to spec” to run the current version of NeurOptimal®. This will be assessed at the initial mousecall. You will be advised of issues we detect, which you may or may not be able to rectify. Please understand Zengar Institute Inc. may not accept your system for coverage or maintenance under this program.

Please note that every effort has been made in this document to convey accurately both the rights of a PASS member as well as the responsibilities. Zengar Institute Inc. reserves the right to amend, add or delete items as necessary, at any time as a consequence of wisdom gained through experience with PASS. Any user applying for membership is assumed to be knowledgeable of, and in agreement with, the above terms of service.

Loaner Service: We do our best to assure you receive quality hardware, including extensive testing of your personal hardware prior to delivery. Occasionally hardware can eventually fail, and these always need to be repaired off premises. We know the upheaval this can cause a business in terms of client cancellation and down time so we offer, exclusively to our PASS members, a special loaner service to help keep down time to a minimum. Once the need for loaner equipment is confirmed we will ship it out to you, often on the same day. All we ask members to do is pay for the shipping.

Ambassador Program:

What is the Ambassador Program? Zengar has developed the Ambassador Program as a way to thank our PASS members for spreading the word about NeurOptimal® and bringing new clients to Zengar. The Ambassador program is a great way for existing PASS members to share their knowledge and supplement their income.

Who is Eligible? The Ambassador Program is open to all PASS members.

What products can be sold? NeurOptimal® Professional Bundles and NeurOptimal® Personal Trainer Bundles

To whom can the ambassador sell? To any individual who is not currently a customer of Zengar (new trainers), to whom a legal sale may be made. Please note- the sale must be to a genuine new user who is not professionally associated with you in any way, nor can the system be placed to the same household or business address. This includes selling to a company name with which you are associated, a family member or friends in the same household. Ambassadors may be banned from the Ambassador program if discovered to have attempted any of the above. If you’re not sure if you qualify please don’t hesitate to contact us at [email protected] with any questions.

How do I get recognized as the Ambassador for a particular sale? The PASS member is only considered an Ambassador for a particular order when they deliver the purchase order (fax or online shopping cart) to Zengar or have their name submitted by the client at the time the order it placed. Regretfully, we cannot compensate a PASS member whose name is not submitted at the time of the order. A potential purchaser may contact a number of trainers out of their own due diligence to speak to them of their experiences of the system, it is up to you to decide whether you wish to spend time answering the persons questions or not.

Remuneration: The PASS member who successfully places a system with a new user and whose name is indicated at the time of order will be remunerated up to 10% on any Personal or Professional Bundles of the collected purchase price dependent on the product introduced and placed. This percentage is calculated on the base purchase price exclusive of any taxes, duties, shipping or other extraneous costs that may be added to prices to facilitate the sales process locally. These are always calculated on the base price in USD, even though prices may be converted into currencies locally. If Zengar refers a client to an Ambassador, or if there are two Ambassadors named on a sale, the remuneration will be reduced to 5%.

Payment: Payment is made via Paypal or may be credited to your Zengar client file, to be used toward future purchases. After the client (“customer”) submits their order listing you as their ambassador you will receive an e-mail from Zengar letting you know that you have been named as an Ambassador along with the necessary details of the order. In order to receive payment please send an e-mail to [email protected] within 30 days of receiving that e-mail that clearly indicates your name, client name, “Ambassador Fee” amount and the e-mail address linked to your paypal account. Should the customer opt for in house financing remuneration will be made 3 months from the sale date or at the time the 3rd payment is made, whichever is later. Should you prefer to hold the funds as a credit toward future purchases with Zengar please indicate this in your e-mail. Ambassador fees may not be applied to the sale invoice- they are fees available for collection only by the rightful ambassador of a qualifying NeurOptimal® product sale. Should the Ambassador be past due on any Zengar account the Ambassador fee will be applied toward that balance. Should the Ambassador currently have an in-house financing balance, the ambassador fee will be place in a “ZenCredit” account. The ambassador can then use these funds to pay for future financing installment payments, other Zengar purchases or receive as payment when the financing term is completed and in good standing.

Returns: Should the client return the purchased system to Zengar for any reason, the ambassador fee will be reimbursed to Zengar within the following 30 days. Failure to provide the reimbursement within that 30 day period may result in PASS benefit access being denied and Ambassador status suspended.

Representative Status: Any Ambassador who places 6 bundles or more during one calendar year is eligible to move up to Zengar Representative Status. Please contact [email protected] for more information.

Limitations: An ambassador may not offer a sale price differing from the www.zengar.com price (non-PASS discounted). Rebate incentives are not permitted. Ambassador Fees are offered on new clients first invoice only and not toward any subsequent purchases at a later date. Regretfully, an ambassador cannot be compensated for a sale that does not list them as the ambassador at the time of purchase. We suggest you aid in the placement of the client order to ensure you are named as the Ambassador or explain the importance of including your name to your client.
