When you rent from us you'll be assigned a neurofeedback trainer coach to guide you if you are in need of extra help. Every rental includes a printed manual on how to use the system as well as how to troubleshoot. Usually a reboot of the system helps but if not, email your rental manager or use the chat widget on our website with a description of the problem and include the best way/time to reach you. It's important that you read the print out that came with the equipment and follow our guidelines how to handle the equipment.
