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 if on 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 wired or Bluetooth headset to automatically switch audio to the headset.
The MC55 defaults to handset mode. When a wired headset is plugged into the MC55 audio connector or 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
4, 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.
NOTE If the mobile computer goes into suspend mode while using a Bluetooth headset, the headset disconnects
from the mobile computer. The mobile computer defaults back to handset mode.
