Unfortunately this doesn't seem to work for the 740. There's already a folder called Contacts. Within this folder there are 3 other folders. They're labeled Buddies.dat, Called and Inbox. I would assume the Buddies.Dat is the file to edit. However, Windows reports it can't open this folder, and directs me to a web search which isn't much help. Properties says that this folder opens with Windows Shell Common. I can't find much in the way of opening that type of file. I suppose I could try renaming it, editing it, and then putting back the original name, but I'm reluctant, as I don't want to screw anything up, and I don't know that it will work anyway. I found that the Called subfolder is editable with notepad, so I was able to insert 10 names and numbers that it seems to retain. I can access these with the 'Recently Called' function on the 740. In a way that works as a small indirect phonebook although it only retains the last 10 numbers, and will obviously change as I call different numbers. As a last resort I tried creating my own Contacts folder, but try as I might, it will only retain the property of 'Read Only'. I've edited the properties to take away the Read Only Tag, hit the Apply button, only to find it reverts to Read Only, so I can't edit it. I suppose I should contact customer support and see what they say about manual entries, but for the money this unit cost me, I think it's ridiculous to have to do that. Anyway, thanks for your help.
