Troubleshooting

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

The battery does not charge.

•Make sure that the battery is securely installed in the cordless headset.

•If the cordless headset is in its headset charger but the light on the headset does not turn on, refer to The light on the headset is off while charging on page 24.

•Charge the battery in the cordless headset for at least three hours. For optimum daily performance, return the cordless headset to the headset charger when not in use.

•You may need a new battery. Refer to the Battery installation section on page 6.

•Your headset might be defective. Refer to the Limited warranty section on pages 34-37 for further instructions.

I cannot dial out.

•Try all the suggestions above.

•You must use a telephone on the same line to dial out. Once you have dialed the number, you can press to join the call.

•If other phones in your home or office are having the same problem, the problem is in your wiring or local service. Contact your telephone service provider (charges may apply).

My cordless headset isn’t performing normally.

•Make sure the power cord is securely plugged into the headset charger. Plug the unit into a different working electrical outlet not controlled by a wall switch.
