Abstract

Abstract of the Disclosure A radio telecommunication apparatus comprises a volume key for controlling volume, detecting means for generating a first detection signal in response to con-tinuous push of the volume key, and generating a second detection signal in response to intermittent push of the volume key, and voice volume control means for per-forming control to increase the volume in response to one of the first and second detection signals, and per-forming control to decrease the volume in response to the other of the first and second detection signals.
