ABSTRACT:
A facsimile apparatus incorporating a cordless telephone set includes a base unit transmitting and receiving a signal to and from a remote unit with a radio signal, and a facsimile communication device. During voice communication with the remote unit via a telephone line, an alarm is issued to the user when the voice communication continues for more than a predetermined time period. An alarm is also given to the user of internal line voice communication when there is a telephone call from an external line during voice communication between the base unit and the remote unit. Therefore, the reception of a reception signal to the facsimile apparatus is not inhibited because an alarm is issued when voice communication continues for more than a predetermined time period and when there is a telephone call from an external line during internal line voice communication.
