Safety and Performance Information

The following sections provide information about the impact of power outages and external devices on your Cisco Unified IP Phone.

Power Outage

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

External Devices

Cisco recommends using good quality external devices such as headsets, cables, and connectors that are shielded against unwanted radio frequency (RF) and audio frequency (AF) signals.


Note

Not all Cisco IP Telephony products support external devices, cords or cables. For more information, consult the documentation for your 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 these 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 external devices, 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].

  • Administrative tasks, such as an internal port scan or security scan

  • Attacks that occur on your network, such as a Denial of Service attack
