    • A radio telephone apparatus including a base unit connected to a wire line and a radio telephone unit connected to the base unit via a radio communication link. The apparatus has an instantaneous conversation function for establishing a conversation state by detecting that the radio telephone unit has been lifted up in a standby state, and also has a talk commencing/terminating key allowing a command for commencing a conversation and a command for terminating the conversation to be inputted alternately. A time guard controlling circuit is also provided for invalidating an input operation of the talk commencing/terminating key if the talk commencing/terminating key is operated during a preset time. Simultaneously as the conversation state is established by lifting the radio telephone unit in the standby state, the preset timer is started, and even if the talk commencing/terminating key is pressed during the preset time of the timer, the input operation is invalidated and the conversation state is maintained.
