Each telephone has a unique "address." You can move your 3Com Cordless Telephone's base unit to another location, connect it to any RJ45 jack on the LAN, and still maintain all of your personalized features, speed dials, and extension number. Because your extension number and personal settings are associated with your physical telephone, only your administrator can move phone extension settings from one telephone to another. Always unplug your telephone from the power source and from the network before you clean it. Use a soft cloth dampened with mild detergent. WARNING: Failure to unplug the telephone before you clean it could result in electrical shock.
