Abstract
A communication device is provided in which, in case of a power failure caused by an earthquake, a slave unit can be used as an illumination device, which includes a high-visibility display portion, in which notification lamps to be lit or blinked can be selected by a user, and in which the color of an incoming lamp that is lit at the time of normal reception can be prevented from being similar to that at the time of reception of the earthquake early warning. When a predicted period up to the arrival of a primary shock is calculated, the lighting and extinguishing of backlights arranged behind a group of operation buttons is controlled, and any of digits from 0 to 9 is displayed on an input portion. The colors of the lit backlights are changed according to the value of a predicted seismic intensity, and the predicted period is displayed. The color of the incoming lamp lit when the earthquake early warning is received cannot be set at the color of the incoming lamp lit when normal reception is performed. The user can select the incoming lamps to be lit or blinked.
