Troubleshooting

		telephone line to allow all of them to ring
		simultaneously. Try unplugging some of the other
		phones.
	•	The layout of your home or office might be limiting
		the operating range. Try moving the telephone base
		to another location, preferably on an upper floor.
	• If the other phones in your home are having the same
		problem, the problem is in your wiring or local
		service. Contact your local telephone company
		(charges may apply).
	•	Test a working phone at the phone jack. If another
		phone has the same problem, the problem is the
		phone jack. Contact your local telephone company
		(charges may apply).
	• Other electronic products can cause interference with
		your cordless phone. Try installing your phone as far
		away as possible from electronic devices such as
		wireless routers or other cordless telephones.
	•	Re-install the battery, and place the cordless handset
		in the telephone base. Wait for the cordless handset
		to re-establish its connection with the telephone
		base. Allow up to one minute for this to take place.
	•	Your line cord might be malfunctioning. Try installing
		a new line cord.
