Definitions

• a known problem for users of cellular telephones and cordless telephones is the fact that it may be stressful to manage to switch the ringing off in time when the telephone rings at inappropriate moments.
• Another problem may be to manage to answer in time, when answering involves a plurality of actions, such as picking up the telephone from a pocket or bag, flipping a lid open, identifying the appropriate button and activating the same.
• buttons are necessary for certain basic functions. This is accomplished most easily by placing the concerned buttons in such a way that they may be easily located using both touch and eyesight. By placing the buttons on the more narrow sides of the telephone, or in some other way well isolated from the normal numerical button set, the buttons will be more easily identifiable both visually and tactilely. The latter makes it possible to easily locate the buttons without removing the telephone from a bag or pocket. It is consequently even possible to push the buttons through garments, which increases the speed of the answering process. It is common to grip over the largest surfaces and not the smallest when removing a telephone from a pocket or a bag.
• buttons When the functions are defined so that more than one button will have to be pressed, a high degree of security is attained against unintentional activation. The probability that a telephone will get jammed from both side edges simultaneously is small. Furthermore, additional safety may be provided, if necessary, by recessing the buttons or by providing protective protrusions along their sides. If the buttons are placed on the more narrow sides of the telephone, the risk of unintentional activation is further reduced.
• An object of the present invention is to make it possible to easily and securely answer a telephone call, on a cellular telephone or a cordless telephone, faster than conventional technology allows. This is accomplished using a new form of button set.
• buttons are designed to provide maximum tactile identification possibility and to minimize the risk of erroneous input, which is achieved by providing cellular telephones and cordless telephones with two buttons which control a number of basic functions while being simultaneously activated in different ways.
• buttons are designed to minimize the risk of erroneous input and to maximize the tactile identification possibility by being located in such a way that the risk of simultaneous activation is minimized while, at the same time, the buttons are easily identifiable, which is achieved by placing the buttons on opposite sides of the telephone and preferably on the short sides of the telephone, and by placing the buttons in a protrusion or in a recess.
• buttons on opposite sides are unintentionally pressed simultaneously, in case someone would choose to grip the short sides of the telephone to remove it from a pocket, the buttons may be placed at somewhat varying heights, so that they are not placed directly opposite each other.
• buttons may also be doubled by varying the time the button is kept depressed to generate different signals to the telephone. A longer depression may mean On/Off and a shorter Off hook/On hook.
• a further embodiment is to place two buttons next to each other on the same side of the telephone and to assign them different functions for different combina- tions of button depressions.
• buttons By placing these buttons on the end side or sides of the telephone, the effect is that they become easily tactilely identifiable and can be activated through, for example, the cloth when the telephone is lying in a pocket.
• the operation may be that they have certain functions when they are activated separately and other functions when they are activated together with one or more buttons on the opposite side.
• buttons may be activated by depressing any one of these buttons or both in combination with one or more buttons on the opposite side.
• the concerned basic functions are On/Off, On hook/Off hook, Signal off/Signal on.
