1. A communication terminal apparatus for making radio communication, comprising:
- a speaker;
a microphone;
a first amplifier which varies a level of a speech signal to be outputted by the speaker;
a second amplifier which varies a level of a speech signal inputted by the microphone;
a first memory which stores first information for respectively setting the gains of the first and second amplifiers at predetermined values, and for storing second information for respectively setting the gains of the first and second amplifiers at predetermined values different from the values of the first information;
means for designating any one of the first and second information;
a second memory which stores the information designated by the designating means;
means for controlling the gains of the first and second amplifiers based on the designated information stored in the second memory;
means for connecting to an external device capable of speech input/output;
means for detecting a connection to the external device and a disconnection from the external device; and
means for switching the speech input/output by the microphone and speaker to the speech input/output by the external device when the detecting means detects the connection to the external device, and for switching the speech input/output by the external device to the speech input/output by the microphone and speaker when the detecting means detects the disconnection from the external device;
wherein the controlling means controls the gain of the first and second amplifiers based on the designated information stored in the second memory when the detecting means detects the disconnection from the external device.

Abstract
A control section preliminarily stores in a memory section hands-free setting data indicating whether or not a hands-free communication function is set before connection of a car kit and, if the car kit is disconnected, resets the data to an operated condition before the car kit has been connected.
