Let's face it...the people who hate technology, but love to watch TV and listen to their favorite music are our customers. After they watch me install a system that takes hours or months, they have already convinced themselves they won't be able to operate it. During the sale and installation process I reassure them they will be able to operate it...and promise a customized cheat sheet on my letterhead. I also add they won't need it. I provide cheat sheets...even for Universal Remotes...because it is for the customer's peace of mind. Otherwise, I have to explain I won't provide the cheat sheet because I can work their system and I don't think they need it...rather awkward.
