Troubleshooting Tips
If your voice is too quiet to be heard clearly at drive up
• Increase volume by turning up the mic volume dial one
increment at a time.
If your headset interferes with other DECT headsets nearby
• Reduce wireless range by pushing switch 3 down.
If battery life is not adequate
• Turn off the headset between calls (single press Link button
once to toggle “on” and “off”).
• Increase battery life by using narrowband transmission -
push switch 5 down (may reduce sound quality).
For more information, see the D10 Series manual included with this headset.
