The watch uses radio signals to connect to wireless networks.  Observe signs and notices that prohibit or restrict the use of electronic devices (for example, in healthcare facilities or on airplanes). 

Although the watch is designed, tested, and manufactured to comply with regulations governing radiofrequency emissions, such emissions may affect or interfere with the operation of other electronic equipment. Use Airplane Mode when use is prohibited, such as while traveling in aircraft, or when asked to do so by authorities.
