A while ago their was quite a lively discussion on this list of the book ports imbalance when laid on it's back. Main points being, when it is in that position using the six buttons at the bottom of the telephone stile key pad causes it to tip because of the belt clip affixed to the back of the unit. I have given this design flaw a good bit of thought from time to time and considered some complicated fixes and a couple of simple solutions. Well, you could just fold a paper napkin to the correct thickness and place it under the and of the book port and actually that works pretty well. I have a small shop so, I considered building a wooden cradle for the appliance but, gave that idea up, to much trouble. I removed the screws holding the case together and found my nerve flagging when it came to removing the works of the book port to get to the belt clip. Of course any work around must be accomplished with out compromising the integrity of the cover to the battery compartment. For what it is worth here are today's final solutions to this vexing little problem. You may or may not no you can buy Velcro strips in several different lengths and sizes at many retail stores. Of course Wall-Mart, I would think all dollar stores, and most pharmacies would have it. What I have seen has the mail and female locked together and has a peal off backing on both. I cut a peace slightly smaller then the battery cover, pealed off the film covering the sticky stuff on the back of the mail and affixed it to the door. Then I found a peace of cardboard the correct thickness, and attached the female Velcro to said cardboard. I even went one step further and put a peace of Velcro on the arm of my recliner so when I recline or leave the chair rapidly the book port remains in place. I am not touting this as the only or even the best solution to the problem, just one of many and also, one that works very well. Phil Parr.
