Cisco Systems CP7945G manual Cisco Product Security Overview, Power Outage, Using External Devices

Getting Started

Power Outage

Your accessibility to emergency service through the phone is dependent on the phone being powered. If there is an interruption in the power supply, Service and Emergency Calling Service dialing will not function until power is restored. In the case of a power failure or disruption, you may need to reset or reconfigure equipment before using the Service or Emergency Calling Service dialing.

Using External Devices

When you use external devices with the Cisco Unified IP Phone, Cisco recommends the use of good-quality external devices, such as headsets, that are shielded against unwanted radio-frequency (RF) and audio -requency (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 these actions:

•Move the external device and its 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).
