Important Electrical Considerations Unplug all electrical appliances when you know an electrical storm is approaching. Lightning can pass through your household wiring and damage any device connected to it. This phone is no exception. Warning: Please do not attempt to unplug any appliance during an electrical storm.
Radio Interference Radio interference may occasionally cause buzzing and humming in your cordless Handset, or clicking noises in the Base Unit. This interference is caused by external sources such as TV, refrigerator, vacuum cleaner, fluorescent lighting, or electrical storm. Your unit is NOT DEFECTIVE. If these noises continue and are too distracting, please check around your home to see what appliances may be causing the problem.
Installation Selecting a Location Before choosing a location for your new phone, there are some important guidelines you should consider: • The location should be close to both a phone jack and continuous power outlet. Note: A continuous power outlet is an AC outlet which does not have a switch to interrupt its power. • Keep the Base Unit and Handset away from sources of electrical noise such as motors or fluorescent lighting. • Be sure there is sufficient space to fully extend the Base Unit antenna.
Connecting the Telephone Cords Consider these safety guidelines before connecting the telephone cords: CAUTION: • Never install telephone wiring during a lightning storm. • Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected. • Use caution when installing or modifying telephone lines. Applying Power to the Base Unit All the XC645 phones require an AC outlet, without a switch to interrupt power, and the included AC Adapter.
Adapter Safety Feature The AC Adapter furnished with this phone may be equipped with a polarized line plug — a plug having one blade wider than the other. This plug will fit into the power outlet only one way. If you are unable to insert the plug fully into the outlet, try reversing the plug. Do not alter the shape of the blades of the polarized plug.
