Query: Unbearable static 20 feet from base

I love this phone. Bought it for my elder parents. However it has some shortcomings that all but overshadow the good:* Very poor range. One room over -- less than 20 feet -- and it is static city. Double that distance and you are out of range completely.* Clock goes out after every power outage (despite the advertised feature of "keeps phone working even during power outage").* Call 911 button too big and easy to hit by mistake.* Curiously small answering machine buttons.
