Why does my AT&T Telephone headset not work at all?
The headset is not getting power from its battery. Verify that the battery is installed and charged correctly. Place the headset into the accessory charger. Ensure the charger is securely plugged into an outlet not controlled by a wall switch. The headset LED will light to indicate that the headset is charging. If the battery is completely depleted, it can take up to 10 minutes to charge the battery enough for the headset to work even briefly. In this case, the ON/OFF LED will remain off and you will not be able to use the device. After 10 minutes of charging, remove the headset from the charger and press ON/OFF on the headset or (HEADSET) on the Deskset to turn on the headset. Replace the headset battery.
