COMMUNICATION DEVICE

摘要

It is an object to provide a communication device which includes a subsidiary device that can be used for a lighting device at the time of the occurrence of a power failure due to an earthquake, a highly viewable display unit, a turning-on or blinking alarm lamp that a user can select, and a incoming call lamp prevented from indicating the same color between ordinary time and emergency earthquake announce receiving time. When an estimated time up to the arrival of a main tremor is calculated, the communication device controls turning on/turning off a backlight set behind a group of buttons to display numbers from 0 to 9 on the input unit. A turning-on color of the backlight is changed in accordance with a value of an estimated tremor to display the estimated time. Further, a color with which the incoming call lamp turns on at the emergency earthquake announcement receiving time can never be set to be the same as a color with which the incoming call lamp turns on at the ordinary call receiving time. Further, a turning-on or blinking incoming lamp is made available for a user to select.
