Using External Devices The following information applies when you use external devices with the Cisco Unified IP Phone: Cisco recommends the use of good quality external devices that are shielded (screened) against unwanted radio frequency (RF) and audio frequency (AF) signals. 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 headsets that are fully compliant with the EMC Directive [89/336/EC]. Installing the Cisco Unified IP Phone You must connect the Cisco Unified IP Phone to the network and to a power source before using it.
