Thank you steve. I just keep the unit at home for home use or where there is no necessity for quiet. I don't want to send it to freedom. If I decide to try something on the way of the springs such as are in the braille lite, ... but if it isn't yet being done, I don't want mine to be the first unit. But thank you so much. I'll keep looking into it. If anyone hears of its being tried, I'd love to know. Thank you all. Penny Golden pgolden@xxxxxxxxxxxxxx
