To enable a test product to be moved on a production line in an assemble line system, efficiently transferred between processes, reduced in man- hours, and improved in productivity by a method wherein carrying-in and -out ports through which the test product is made to pass are provided in a shielded room for a talking test.
A carrying-in port 4 and a carrying-out port 5 for a test product such as a portable transceiver in arbitrary opposed side faces, for example, on the left and right side of the room 1. The carrying-in port 4 and the carrying- out port 5 are so set in size as the enable the test product to pass through. A carrying-in door 6 and a carrying-out door 7 both possessed of a shielding effect are provided in the carrying-in port 4 and carrying-out port 5 respectively, whereby radio waves are prevented from leaking out of the shielded room 1. By this setup, a test product is not required to be manually loaded into or unloaded from a shielded room each time the test product is subjected to a talking test, so that the test product can be moved on a production line in the conveyor system. Therefore, a product can be reduced in manufacturing man-hours and improved in productivity.
