Chapter 3 Setting Up the Cisco Unified IP Phone Installing the Cisco Unified IP Phone • 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].

See Figure 3-2 for a graphical representation of the connections. Note Before you install a phone, even if it is new, upgrade the phone to the current firmware image.
