CHAPTER 3 CALLS
Introduction
This chapter discusses making a phone call from the Phone application, the Contacts application or other
applications or widgets that display contact information.
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.
Audio Modes
The device offers three audio modes for use during phone calls:
•
Handset Mode: Switches audio to the receiver at the top front of the device, so the user can use the device
as a handset. This is the default mode.
•
Speaker Mode: Use the device as if on speaker phone.
•
Headset Mode: Connect a Bluetooth or wired headset to automatically switch audio to the headset.
Using a Bluetooth Headset
Use a Bluetooth headset for audio communication when using an audio-enabled application. See Bluetooth on
page 6-16 for information on connecting a Bluetooth headset to the device. Set the volume appropriately before
putting on the headset. When a Bluetooth headset is connected, the speakerphone is muted.
NOTE Emergency numbers vary by country. The phone’s pre-programmed emergency number(s) may not work
in all locations, and sometimes an emergency call cannot be placed due to network, environmental, or
interference issues.
