I am having a hard time programming the keys. No where in the manual does it say how to clear the entire board. It also says that I need to activate the keys in order to program them, but I can't find how to do that either.
Hi Sara,
I am a cash register dealer and if you are in CT I can help you. Programming is rather involved to be able to explain it here. Feel free to contact me at all-cash-register@comcast.net.
