Read the following safety notices before installing or using your Cisco Unified IP Phone:
IMPORTANT SAFETY INSTRUCTIONS
This warning symbol means danger. You are in a situation that could cause bodily injury. Before you
work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with
standard practices for preventing accidents.
Warning: Read the installation instructions before you connect the system to its power source.
Warning: Ultimate disposal of this product should be handled according to all national laws and
regulations.
Warning: Do not work on the system or connect or disconnect cables during periods of
lightning activity.
Warning: To avoid electric shock, do not connect safety extra low voltage (SELV) circuits to
telephone network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain
TNV circuits. Some LAN and WAN ports use RJ-45 connectors. Use caution when connecting cables.
Caution: Inline power circuits provide current through the communication cable. Use the Cisco
provided cable or a minimum 24 AWG communication cable.
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.
