PROBLEM TO BE SOLVED: To record the fact that a call has been made in a hands-free manner in a portable telephone. SOLUTION: In step 100, it is determined whether hands-free call has been made. An operation history is called from a memory 39, and the determination of the presence of the hands-free speech causes the control to proceed to step 120. In step 110, a navigation system 50 detects the position over a fixed period of time. When the detected position is moving over the fixed period of time, the equipment determines that a vehicle in question is running (step 120). The equipment then records the fact that a hands-free call has been made during the running of the vehicle in a memory 39 as a hands-free call record, and also records it also in an IC card 40 (step 140).
