Query: Worked great for two weeks then died

I got the two handset model KX-TG5110m. It worked great for two weeks. Then came the fatal "System Error #9" all the lights on the base flash like a Christmas tree. I called Panasonic customer service the hold time was 12 minutes. The guy told me the phone was done for. He said it could have been a power serge, I do have the phone plugged into a good serge protector. Oh well, I can't seem to find a phone with better features, so I will exchange it for new one and give it another try.
