5 - 6 MC909X User Guide
Using the Speakerphone and a Headset
You can use the MC9097 with the built-in speakerphone, with a wired headset or a Bluetooth headset. The
MC9097 defaults to speakerphone mode. When a wired headset is plugged into the MC9097 audio connector
or a Bluetooth headset is configured for use with the MC9097, the speakerphone is muted and audio is heard
through the headset.
Adjusting Audio Volume
Use the Volume Control Slider or the keypad keys to adjust the volume of the ringer when not in a call and the
audio volume when in a call.
Figure 5-8 Phone Volume Slider
To adjust the volume tap the Speaker icon in the Status Bar. Move the slider up or down to adjust the volume.
NOTE If the mobile computer goes into suspend mode while using a Bluetooth headset, the headset
disconnects from the mobile computer. The call is not dropped. The mobile computer defaults back to
speakerphone mode.
Phone Volume Slider
NOTE You cannot adjust the audio volume during a walkie-talkie call. To adjust the volume for a walkie-talkie
call, make a regular phone call, adjust the volume during a call and then make a walkie-talkie call. This
setting is used on subsequent walkie-talkie calls.
