If you hear noise or interference during a call
•You may be out of range. Move closer to the base.
•Appliances plugged into the same circuit as the base can cause interference. Try moving the appliance or base to another outlet.
•The layout of your home or office might be limiting the operating range. Try moving the base to another location, preferably on an upper floor.
•If the buttons don’t work, try placing the handset in the base for at least 15 seconds.
•Disconnect the base from the modular jack and plug in a corded tele- phone. If calls are still not clear, the problem is probably in your wiring or local service. Call your local telephone service company.
