Abstract

When the key operation area is pressed, a decision is made about whether the key is pre-registered a single button dialing telephone number or not (step 3). In case a decision is made that a single button dialing telephone number is pre-registered to the key in step 3, the timer starts when the key is pressed (step 6). In case the key is held down for the predetermined period (T1), an operation to instruct single button dialing via a so-called hold-down operation is assumed, thus causing the single button dialing telephone number pre-registered to the key held down to appear on the display (step 8). When a predetermined period (T2) has elapsed with the key held down (step 9), an operation to instruct a call origination to the telephone number on the display is assumed and a call is originated then conversation starts depending on the answer of the distant party (step 10). Keys on the cover can be used to operate keys on the body.
