The headset is an important part of audio quality.PDAs that support stereo headphones with microphones are recommended.The Dell specific headset with a button on the wire, when used with theX51v, allows the MVC 2050 to answer an incoming call or release an activecall by pressing the button.ATTENTIONBluetooth and 802.11b operate on the same frequency band and use the sameWLAN hardware on the PDA. Therefore, the use of Bluetooth accessories withMVC 2050 can lead to poor call quality.Contact your PDA vendor to obtain headset recommendations.Automatic Gain Control and feedbackBecause MVC 2050 requires a headset to operate properly, disableAutomatic Gain Control. Refer to your PDA documentation to disableAutomatic Gain Control.When the PDA is used in handsfree mode, without a headset, the PDAmicrophone picks up sounds from the speaker, which creates a feedbackloop.
