Query: Constant beeping

I was impressed with the reviews for this product and liked the idea of the pet detection feature as my cat has never been around a newborn before. The pet detection feature worked very well and also alerted me when one of my six year old twins was near the baby! However, the parent unit would start beeping that it was out of range numerous times every day. We have a small home (1100 sq ft, two story) and tried many locations for both units with the same result. Three days of running downstairs at all times to reset the parent unit was enough! I called Evenflo since the beep was somewhat different than what was described in the manual for the out of range signal (but also different from the pet detection signal and happened with the pet detection feature off as well) and they could not explain it, so this unit went back to the store. The pet detection feature is a great idea, but they need to improve the range on this monitor.
