PURPOSE:To reduce power consumption and to extend the battery service life by setting a notice time with only a light at the arrival of a call. CONSTITUTION:A notice section 13 is provided with a means, which generates a light over a preset time when the notice section 13 is started by a decoder section 4 and generates a sound succeedingly. With a changeover switch 6 thrown to the position of 'N', a signal from the changeover switch 6 to the decoder 4 is logical H and the decoder 4 discriminates it that the notice means is an LED 10 and a speaker 12. When a carrier selects the position 'N', a driver 9 stimulates the LED 10 at the same time of the reception and drives and sounds the speaker 12 together with stimulation after a preset time (t sec). Thus, the power consumption required for the confirmation of a call is reduced. |
