Sorry I disappeared. Power and wireless went out with a thunderstorm. Look at this thread and click on the link to the poochie-bells and you'll see what I mean. If you are interested, I will try to help you. If not, fine. Everyone has their own approach. Some have them ringing the stationary bell - like at hotel desks.
Any questions, please do not hesitate to ask.
