Claims

[Scope of Claim for Utility Model Registration] Message storage means for storing message data in an intercom for making alternating calls between a handset equipped with a call switch installed outside the house and a base unit installed inside the house. , a set time storage means for storing and setting arbitrary time range data; a clock circuit; and a determining means for determining whether the current time data outputted by the clock circuit is within the time range of the set time storage means. and output means for continuing to output the message data from the message storage means from the handset for an arbitrary time range in accordance with the determination result of the determination means.
