Moving Your
Telephone
All 3Com Telephones have the Automatic Telephone Relocation feature.
Each telephone has a unique “address.” You can move your telephone to
another location, connect it to any Ethernet jack on the LAN, and still
maintain all of your personalized features, speed dials, and extension
number.
Swapping
Telephones
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.
Cleaning Your
Telephone
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.
Troubleshooting
Problems
Table 12 lists possible problems that you may encounter and the most
