Depending on the quality of these devices and their proximity to other devices such as mobile phones or two-way radios, some audio noise may still occur. In these cases, Cisco recommends that you take one or more of the following actions: • Move the external device away from the source of the RF or AF signals. • Route the external device cables away from the source of the RF or AF signals. • Use shielded cables for the external device, or use cables with a better shield and connector. • Shorten the length of the external device cable. • Apply ferrites or other such devices on the cables for the external device. 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. Caution In European Union countries, use only external speakers, microphones, and headsets that are fully compliant with the EMC Directive [89/336/EC].
