Abstract: PURPOSE: A facsimile device capable of controlling the level of a signal coming into a handset is provided to control the level of a dial tone fed back to a receiving end of a handset from a transmission end of a modem through an LIU(Line Interface Unit), thereby reducing noise components included in the dial tone. CONSTITUTION: A key input unit(112) has a dial key. A modem(162) decodes fax data to be transmitted to an outer apparatus connected to the modem through a communication network, and encodes fax data received from the outer apparatus. A handset(164) performs voice communication with the outer apparatus. An LIU(166) selectively connects either the modem(162) or the handset(164) with the communication network, and controls the level of a signal coming into the handset(164). When a dial key signal is inputted through the key input unit(112) while the handset(164) is in hook-off state, a controller(180) connects a transmission end of the modem(162) with the communication network, and controls the LIU(166) to reduce a dial tone, corresponding to the dial key signal, by a predetermined level.
