A radio communication apparatus has a plurality of communication functions such as an incoming call sound, an incoming call ringing pattern, an incoming call vibration, a received voice volume, a microphone sensibility, a noise canceling, a key confirming sound and a message recording, and a plurality of operation conditions of the communication functions are stored in a operation condition storing unit for each of a plurality of operation modes suitable for various environments. When a user selects a particular operation mode suitable for user's environment by pushing a mode selecting button, particular operation conditions of the communication functions corresponding to the particular operation mode are read out, and communication functions of a speaker, a vibrator, a buzzer, a noise canceler, a microphone and a message recorder are simultaneously set to the particular operation conditions. Therefore, when an incoming call and a caller's voice are received, the incoming call is rung at a pattern and a sound volume suitable for the user's environment, and the caller's voice is output at a sound volume suitable for the user's environment.
