PROBLEM TO BE SOLVED: To identify an installation position of each apparatus with accuracy after installation of a plurality of apparatuses. ! SOLUTION: A terminal operator uses a construction instrument having a laser emission function to irradiate a light receiving part of arbitrary one of a plurality of devices with laser light. The arbitrary one device that received the laser light at the light receiving part transmits an ID number given to the own device to the terminal device by using a communication function. The terminal device receives the ID number transmitted from the arbitrary one device, associating the received ID number and an installation position of the arbitrary one device with each other on the basis of the installation position of a device that the terminal operator identified as the arbitrary one device, in an arrangement drawing of the plurality of devices, displayed on the display part, and transmits the associated ID number and the installation position of the arbitrary device to a |
