Hi @cmickie ,
Do you mean the in use red light on the base station or the red light on the phone?
Have you initialized the replacement phone with the base station, by placing the phone in the base station cradle? The base station in use red light will flash until initialization is completed
You may have to remove the batteries from the "current" handset when you do this as it appears that the base station can only handle one phone and the "current" phone may be still communicating with the base station even though it isn't in the cradle.
