The first wireless module and the second wireless module are in a wireless connection with each other. The second wireless module detects a received signal strength indicator value of the wireless connection. If the received signal strength indicator value is lower than a predetermined signal strength value, the positioning module is enabled to generate plural position data within a predetermined time period. Moreover, the second processing module calculates a displacement of the portable electronic device according to the plural position data and determines whether a warning mode is enabled according to the displacement.
