out.	•	Make sure you have a dial tone before dialing. The
		cordless handset may take a second or two to find the
		telephone base and produce a dial tone. This is normal.
		Wait an extra second before dialing.
	•	Eliminate any background noise. Noise from a television,
		radio or other appliances may cause the phone to not
		dial out properly. If you cannot eliminate the background
		noise, first try muting the cordless handset before
		dialing, or dialing from another room in your home with
		less background noise.

		problem, the problem is in your wiring or local service.
		Contact your local telephone company (charges
		may apply).
