Abstract
A comparing unit,, when a radio unit,receives a radio signal, compares an ambient noise level detected by a noise sensor,with a preset threshold value. If the ambient noise level is smaller than the threshold value, the comparing unit,outputs a set value signal SH, and sets a receiving voice level set value of a receiving voice level setting unit,to “SMALL”, a transmitting voice level set value of a transmitting voice level setting unit,to “LARGE” and a calling sound level set value of a calling sound level setting unit,to “SMALL”, respectively. By contrast, if the ambient noise level is larger than the ambient noise level, the comparing unit,outputs the set value signal SH and sets the receiving voice level set value of the receiving voice level setting unit,to “LARGE”, the transmitting voice level set value of the transmitting voice level setting unit,to “SMALL” and the calling sound level set value of the calling sound level setting unit,to “LARGE”, respectively.
