Further, the auto-in unit 4 is installed near the AV equipment, and the control signal and remote control signal are converted into optical signals by the remote control transmitting section 4d, and outputted from the optical output section 7 via the optical cable 6. Therefore, the light output section 7 is arranged close to the remote control light receiving section 1a of the television receiver 1 in the light receiving direction. On the other hand, a broadcast signal such as a UHF band received by an antenna and a video signal from the camera 3 are mixed in a mixer 8, and this mixed signal is input to the television receiver 1. In that case, when setting the channel by the changeover/setting switch section 4C, it is necessary to set the channel to an empty channel.

In this way, after the video interrupt time and video channel are set by the changeover/setting switch section 4C, when the visitor operates the intercom 2, the auto-in unit 4 switches the television receiver 1 to the set channel. , and a control signal for interrupting the image by the camera 3 for a certain period of time is optically output. Then, the image of the camera 3 is displayed on the screen of the television receiver 1 for a certain period of time. Further, when a remote control signal is generated from the remote control 5, the auto-in unit 4 performs a conventional process, and a control signal corresponding to the operation of the remote control 5 is optically output to the television receiver 1.

Then, the channel of the television receiver 1 is switched or the volume is increased or decreased.

[Problems to be Solved by the Invention] By the way, the above-mentioned auto-in unit seems to be convenient for the user because it is possible to arbitrarily switch the video interrupt time and set a plurality of video channels using the changeover/setting switch section 4c. .

However, since the changeover/setting switch section 4C is manually operated and requires somewhat troublesome operations such as having to set a dummy for the video channel settings, incorrect operations or settings may be performed. Another problem is that, for example, one interrupt time may be changed to a longer one, or the video channel to be interrupted may be set to a television broadcast channel. That is, since the image of the camera 3 is displayed on the screen of the television receiver 1 for a long time, the interruption of the television broadcast may become longer, or the television broadcast may not be watched due to the above-mentioned incorrect channel setting. was.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide an auto-in unit that can issue a warning in case of an operation error or a setting error of a changeover/setting switch.
