Good catch there, Six Cats! Couldn't pass up your name, but do you have six cats? Well, I have seven cats, used to my 9 until 2004 when Muffin passed away from kidney failure when she was almost 17 and this year, I lost Greystone (my avatar), he was barely 5 years old, again, from kidney failure. I had a close brush with Boo, my 16 year old black cat, they though it was liver failure and possible cancer, but his organs are fine for his age and there is no cancer that is detected so it was diagnosed as an infection of unknown origin. I have a cat turning 19 this month, Pansy, my diluted calico, she had a hyperactive thyroid, we got her on meds but there are times her dose needs adjustment, a week and a half ago, her thyroid was out of whack and she had fluid on the lungs so we had to get that taken care of but now she is doing fine and is active again, she still acts like a kitten.
Sorry for being off the subject, if you go to Radio Shack's website, I do believe they have manuals there you can download if you take a little time to search for it, at least they did the last time I was looking around.
Wish I had your luck or even my fathers, he found a Handspring Visor Deluxe as a St. Vincent Du Paul's for 5 bucks. Then again, he is retired and has more time to do that than I do, I work in accounting for the ground division of a major shipping company so things get busy at times.
