Solution
• Reduce speaking volume by changing the speaking volume
major adjust switch setting. See page 16.
• Point microphone towards your chin.
• Listening volume too high on phone. If your phone has a
handset volume control, lower this until the distortion
disappears.
• If the distortion is still present, lower the listening volume
adjust button on the headset. If the distortion persists,
select another listening volume major adjust switch setting.
See page 15.
• Base is too close to computer or phone. See page 9 for
proper positioning.
• System needs to be reset. Perform system reset as
described on page 21.
Speaking volume is too high. Lower the speaking volume by
adjusting the speaking volume minor adjust buttons on the
base. If the volume is still too high, select another speaking
