My telephone doesn’t work at all.

•Make sure the power cord is securely plugged in.

•Make sure you plug the battery connector securely into the cordless handset.

•Make sure you plug the telephone line cord securely and firmly into the telephone base and the telephone wall jack.

•Charge the battery in the cordless handset for at least 16 hours. For optimum daily performance, return the cordless handset to the telephone base or charger when not in use.

•If the battery is depleted, it might take approximately 30 minutes to charge the handset before it shows Low battery. See page 6 for details.

•Reset the telephone base. Unplug the electrical power. Wait for approximately 15 seconds, then plug it back in. Allow up to one minute for the cordless handset and telephone base to reset.

•You may need to purchase a new battery. Please refer to Battery installation and charging in this user’s manual on pages 6-7.

I cannot get a dial tone.

•First try all the suggestions above.

•Move the cordless handset closer to the telephone base. You might have moved out of range.

•If the previous suggestions do not work, disconnect the telephone base from the telephone jack and connect to a different phone. If there is no dial tone on that phone either, the problem is in your wiring or local service. Contact your telephone service provider.

•Your line cord might be malfunctioning. Try installing a new line cord.

I cannot dial out.

•First try all the suggestions above.

•Make sure you have a dial tone before dialing. The cordless handset might 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 might 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 with less background noise.

•If the other phones in your home are having the same problem, contact your telephone service provider (charges might apply).
