Safety Guidelines

•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe. Never install equipment that appears damaged.

•Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Use the following guidelines when you work with any equipment that is connected to telephone wiring or other network cabling, even if that equipment is disconnected from its power source.

•Never install telephone wiring during a lightning storm.

•Never install a telephone jack in a wet location unless the jack is specifically designed for wet locations.

•Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

•Use caution when installing or modifying telephone lines.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Warning Before you work on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and the heat can cause serious burns or weld the metal object to the terminals.

Warning Read the installation instructions before you connect the system to its power source.
