PURPOSE:To safely hold a control parameter, and to dispense with a backup power source by providing a mobile station with a storing means consisting of an EEPROM to store the control parameter needing to be rewritten. CONSTITUTION:A RAM 15 to be used as a work area, etc., and the EEPROM 11 for registering telephone number data are connected to the control part 9 of the mobile station 2. The desired one key of a read/write key 101 and a one-touch key 103 is pushed down, and afterward, after a desired telephone number is inputted by a ten-key 104, by pushing down the read/write key 101 again, said telephone number is stored in the EEPROM 11 as being made to correspond to the one-touch key 103. Thus, by constituting a memory for storing the dial data necessitated to be rewritten of the EEPROM, power consumption is reduced, and the life of a battery is elongated, and simultaneously, the backup battery, etc., is dispensed with. |
