Note To see additional safety warnings and translations of the safety warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information for the Cisco Unified IP Phone 7900 Series that is shipped with your Cisco Unified IP Conference Station 7936. Using External Devices with Your Cisco Unified IP Phone The following information applies when you use external devices with the Cisco Unified IP Phone: • 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 screened cables for the external device, or use cables with a better screen 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].
