Radios
Your device has a separate GSM radio and wireless LAN radio. Switching off the device by pressing the power key on the device
cover switches off both radios.
Note, however, that switching off the device or using the offline profile does not prevent you from establishing a new wireless
LAN connection. Therefore, remember to comply with any applicable safety requirements when establishing and using a wireless
LAN connection.
See "Setting the offline profile," p. 23.
