Aspects described herein relate to communication settings in wireless devices and in particular, to communication settings in waterproof wireless devices. A data packet comprising data sufficient to identify a network connection with which the data packet is associated is received. By the detected contact voltage, it can at least be determined whether the input voltage has been through-connected to the output or switched off. A cutter ring is adapted to mount on an outer circumference of the stepped portion of the back plate, and a fastening member is adapted to connect the cutter ring with the back plate. A plurality of peripheral areas are provided around the central display area, and are adapted to automatically and sequentially display various weight-related data. The magnetic force holds the insert piece into position, eliminating the need for any additional holding structures in the foaming tool.
