A handy phone capable of performing infrared communication with an external apparatus is disclosed. As soon as the phone searching for the other station at the beginning of communication detects data via its infrared receipt section, it alerts the user of the detection of a bit error. Therefore, when the received data is free from a bit error, the phone can immediately inform the user of the phone of the fact that physical connection of the phone and the other station has no problems, even before a station location command is sent in all the slots. This eases the user's mind at the earliest possible stage. Further, the phone of the present invention is capable of immediately reporting the fact that the distance between infrared ports or the angle between the axes of the ports may not be adequate to the user, urging the user to correct the distance or the angle immediately.
