The handle was fitted in size according to the dimensions of an average face, which had been taken as the starting point of the design process. In the completed product, the distance between the transmitter (mouth piece) and the receiver (ear phone) was noticeably shorter than earlier models. The handle was made as light as possible to minimize the stress inflicted upon the wrist and blood veins of the speaker during long calls. The weight of the base unit was also minimized especially for logistical and packaging reasons. The dial finger wheel and face plate consisted of several parts and was designed so that it could be replaced with a set of buttons in a later version of the phone.
