Turning Airplane mode on or off

In many countries, you are required by law to turn off wireless devices while on board
an aircraft. A way to turn off wireless functions quickly is to switch HTC Amaze 4G to
Airplane mode.
When you enable Airplane mode, all wireless radios on HTC Amaze 4G are turned off,
including the call function, data services, Bluetooth, and Wi-Fi. When you disable
Airplane mode, the call function is turned back on and the previous state of Bluetooth
and Wi-Fi is restored.
To turn Airplane mode on or off, press and hold Power, and then tap Airplane mode.
When enabled, the Airplane mode icon is displayed in the status bar.
