2. From the Headset Memory Mode screen, select Enabled.

3. Press .

4. To activate Headset Memory Mode, press  twice. The Headset key will flash to indicate that the phone is in Headset Memory Mode.

Now, whenever you answer a call, the call will connect to your headset automatically.

If you switch to the speakerphone or the handset, you deactivate Headset Memory Mode. Calls will no longer automatically go to your headset, unless you choose this mode. To have calls go to your headset again, activate Headset Memory Mode by pressing  twice.
