Abstract
A wireless device to be mounted on a license plate of an automobile is composed of a casing, components contained in the casing and an operating member inserted into the casing. A battery for supplying power to the components is selectively turned on or off by controlling an insertion depth of the operating member into the casing. At an initial depth, the power supply is turned on for testing the wireless device at a manufacturing plant. At an intermediate depth, the power supply is turned off to save energy consumption in periods of transportation or storage. At a final depth, the power supply is finally turned on for actual use of the wireless device, and the casing is hermetically closed by the operating member.
