My Panasonic Cordless Phone, which is placed in my bedroom as my second phone, stopped ringing and stopped displaying the time a couple of days ago. The following message was all that it would give me: No link to base. Move closer to base, try again. I don't have a manual because this phone was given to me as a gift by my mother, who said she misplaced the manual; therefore, I don't have any idea what that message means. Any assistance would be appreciated.
