Using the Phone 4 - 3
Audio Modes
The MC55 offers three audio modes for use during phone calls:
•
Handset Mode: Switches audio to the speaker at the top front of the MC55, so you can use the MC55 as a
handset. This is the default mode.
•
Speaker Mode: Use the MC55 as a speaker phone. Tap the Speaker On button to activate this mode. Tap
the Speaker Off button to switch back to handset mode.
•
Headset Mode: Connect a Bluetooth headset to automatically switch audio to the headset.
The MC55 defaults to handset mode. When a Bluetooth headset is configured for use with the MC55, the earpiece
and speakerphone are muted and audio is heard through the headset.

Using a Bluetooth Headset
You can use a Bluetooth headset for audio communication when using an audio-enabled application. See Chapter
5, Using Bluetooth for information on connecting a Bluetooth headset to the MC55. Set the MC55’s volume
appropriately before putting the headset on. When a Bluetooth headset is connected the speakerphone is muted.
It is recommended for phone conversations to use the Bluetooth Hands-free profile instead of the Headset profile.
See Chapter 5, Using Bluetooth for more information.
The following dialog box displays when a Bluetooth headset connection is established and the power button is
pressed.
