Using Phone Features

Turning On the Speakerphone During a Call

While a call or three-way call is in progress, you can turn on the speakerphone by simply placing your

device face down.

Your device provides crystal-clear sound quality and voice reception during three-way calls. When the

speakerphone is on, your device also enables the dual microphone to enhance your voice quality and

reduce noise.

When you need to temporarily mute the dual microphone so that the three-way call participants will not hear

you, press the

Mute button. Press it again to unmute.

Turning the Phone On and Off

In many countries, you are required by law to turn off the phone while on board an aircraft.

Enabling or Disabling the Phone

1. Tap Start > Settings > Communications to open the Comm Manager.

2. Tap the OFF/ON slider at the right side of the Phone option to enable or disable the phone function.

When enabled, the

ON indicator is activated.

Enabling or Disabling Airplane Mode

Another way to turn off the phone function is to switch your device to Airplane Mode.

1. Tap Start > Settings > Communications to open the Comm Manager.

2. On the Comm Manager screen, tap Airplane Mode to enable or disable Airplane Mode. When enabled,

the ON indicator is activated.

When you enable Airplane Mode, all wireless radios on your device are turned off, including the phone

function, Bluetooth, and Wi-Fi. When you disable Airplane Mode, the phone function is turned back on and

the previous states of Bluetooth and Wi-Fi are restored.

Note

For instructions on how to make a three-way call, see “Making a Three-Way Call” on page 137 .

Note

When you return from an international trip and you disable Airplane Mode after landing in the United States, your

device will first search for GSM networks if your device has been set to Global mode and was connected to a

GSM network before. A “No Service” status message may first appear on your device. Please wait for your device

to scan for CDMA service and connect to the Nationwide Sprint Network or a CDMA roaming network.
