CALL Control button and then the handset will dial the number you have
dialed latest.
In case you make a call from the Handset, the call will (subject to phone
settings) be automatically transferred to the Headset. If not automatically
transferred, you can transfer the call manually by pressing the CALL Control
button.
5. Last number redialing
Activate last number redial by pressing the CALL Control button on the
Headset. (This will initiate voice dialing with some Handsets.)

Press the VOLUME UP or DOWN Button to increase or decrease the
speaker volume.

button. You can transfer a call to the Headset without ending the call. In the other
case where you want to transfer the call from Headset to Handset, all you do is just
pressing the Call Control button shortly.
