Holding the Device

Your device’s internal antenna is located along the top back 
of the device. Do not block the antenna; doing so may affect 
signal quality and may cause the device to operate at a 
higher power level than is necessary.

Securing Your Device

By default, the device locks automatically when the screen 
times out or you can lock it manually.
