Troubleshooting

I cannot register the headset.

•You must be using a compatible AT&T DECT 6.0 telephone. Visit www.telephones.att.com for a list of compatible telephones.

•Your DECT 6.0 telephone has a maximum number of handsets that may be registered to the telephone base. In terms of registration, the telephone base treats a headset like a handset. Refer to your telephone user’s manual for the maximum number of handsets allowed. If the maximum number of handsets are already registered, you need to follow the deregistration instructions in the telephone user’s manual, then register the handsets and/or headsets you wish to use again, one at a time.

The light on the headset is off while charging.

•Make sure the power and line cords are plugged in correctly and securely.

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

•Make sure the headset is sitting properly in the charger to charge.

•Unplug the unit’s electrical power. Wait for 15 seconds, then plug it back in. Allow up to one minute for the cordless headset and headset charger to reset.

•Clean the cordless headset and headset charger charging contacts each month using a pencil eraser or dry cloth.

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