Using the Phone 4 - 3
Audio Modes
The MC75A offers three audio modes for use during phone calls:
•
Handset Mode: Switches audio to the speaker at the top front of the MC75, so you can use the MC75A as a
handset. This is the default mode.
•
Speaker Mode: Use the MC75A 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 MC75A defaults to handset mode. When a wired headset is plugged into the MC75A audio connector or a
Bluetooth headset is configured for use with the MC75, the earpiece and speakerphone are muted and audio is
heard through the headset.

Using a Wired Headset
You can use a stereo headset for audio communication when using an audio-enabled application. To use a
headset, plug the headset jack into the audio connector on the side of the MC75A. Set the MC75A’s volume
appropriately before putting the headset on. Plugging a headset into the jack mutes the speaker.
For the best audio performance, Zebra recommends a 2.5mm jack headset, see Chapter 7, Accessories.
NOTE While using a Bluetooth headset during a call, the mobile computer will not go into suspend mode.
