ABSTRACT:
A domed member is positioned on the center of a telephone dial. Opposite each finger hole is a raised identifying character such as a Braille number corresponding to the number of the finger hole or a raised Arabic number which can be readily identified by a blind person. A flat on the edge of the member is oriented with the finger stop to assist in locating the member relative to the dial. Preferably the member is removable so that it may be installed and removed while traveling. For such purpose, the base of the member may have pressure-sensitive adhesive, or the member may be hollow and contain a suction cup, or the member may have clips for attachment.
