摘要： Terminal equipment having transmitting and receiving functions for a vehicle radio telephone system has a function thereof limited to one of a plurality of modes depending on the time zone. The equipment is automatically locked when a predetermined period of time expires after the end of a communication. The area wherein a call can be originated on the equipment is limited to one of local, domestic and international areas on the basis of the time zone. A memory has a plurality of addresses each being loaded with a particular telephone number to allow the single equipment to selectively use a plurality of telephone channels, on the basis of the time zone. A plurality of memories each stores a particular speed call number table or a particular unattended telephone message table, so that the tables are selectively used depending on the time zone. Further, the volume level of an alert tone to be produced on the reception of a call and the illumination for a keyboard and a display are controlled on the basis of the time zone.
