6.1 Introduction
•
Optional.
•
Make a phone call from the
Phone
app, the
Contacts
app, or other apps or widgets that display
contact information. This section applies to WWAN devices only.
6.2 Emergency Calling
The service provider programs one or more emergency phone numbers, such as 911 or 999, that the
user can call under any circumstances, even when the phone is locked, a SIM card is not inserted or the
phone is not activated. The service provider can program additional emergency numbers into the SIM card.
However, the SIM card must be inserted in the device in order to use the numbers stored on it. See the
service provider for additional information.
Emergency numbers vary by country. The phone’s pre-programmed emergency number(s) may
not work in all loca-tions, and sometimes an emergency call cannot be placed due to network,
environmental, or interference issues.
6.3 Audio Modes
The device offers three audio modes for use during phone calls:
•
Handset Mode : Switch audio to the receiver at the top front of the device to use the device as a handset.
This is the default mode.
•
Speaker Mode : Use the device as a speakerphone.
•
Headset Mode : Connect a Bluetooth or wired headset to automatically switch audio to the headset.
6.4 Using a Bluetooth Headset
Use a Bluetooth headset for audio communication when using an audio-enabled app. Set the volume
appropriately before putting on the headset. When a Bluetooth headset is connected, the speakerphone is
muted.
6.5 Using a Wired Headset

volume appropriately before putting on the headset. When a wired headset is connected, the speakerphone
is muted.
To end a call using the wired headset, press and hold the headset button until the call ends.
