Dan, You've asked a variety of questions. In order to answer them, we might need a little more information. 1. Cindy is quite right. If all you can get are vertical lines no matter what you do to the knobs, then the Optacon is not working. It will need the services of a repairer. 2. If you can let us know where you live, perhaps another Optacon user would be willing to spend a little time with you and find out if an Optacon would be useful to you at work. It does take practice to learn how to track with the camera with one hand and read the letters and other images on the array with the other. We often suggest that you start with something very easy; a page with a couple of lines of dashes for example. 3. If the Optacon is in its leather case and does not have to be removed from the case in order to use it, you know that you have an Optacon from the r1 series--either b c or d. At the back of the Optacon, above the area that contains the visual display connection and the invert switch, there might be some braille. If there is, you can deduce that the Optacon is an r1c or r1d. If there is no braille, it's probably an r1b or possibly an r1c. Some of the c's had the serial numbers included in braille. Some did not. 4. If the Optacon has to be removed from the leather case altogether in order to access the array and the knobs, then it is an Optacon II. 4. Does the Optacon have a charger to connect it to electricity or does it just have a wire with one end for the Optacon and the other for the plug? Again, if that is all it has, the Optacon is an Optacon II. 5. If the Optacon has been sitting around for a long time, it needs to charge. This assumes that it is an r1 Optacon with a power supply which we usually call a charger. One end of the wire connects to the Optacon. In the middle of the wire there is a rectangular box, then more wire which leads to the wall plug. When you connect the charger to the Optacon and plug it in, within three minutes or so, the charger should begin to feel warm to the touch. If it doesn't, then the charger is not working. To test the charger, you don't have to turn on the Optacon. 6. If the Optacon has no charger, the battery is probably dead or at least not charged. That would account for the vertical lines also. 7. When you open the snaps on the Optacon case and reach inside the front opening, the camera should be tucked in there with its retina cable wrapped around it. If you are lucky, the camera and cable should both be stored in a piece of plastic called the camera rest. Once you slide these out, the array should be reachable. There should not be anything else that you had to do. I think that's enough for you to tell us for now.
