• Use shielded cables for the external device, or use cables with a better shield and connector.
• Shorten the length of the external device cable.

Cisco cannot guarantee the performance of the system because Cisco has no control over the quality of external
devices, cables, and connectors. The system will perform adequately when suitable devices are attached using
good quality cables and connectors.
In European Union countries, use only external headsets that are fully compliant with the EMC Directive
