SWITCHING FROM HANDSET TO HEADSET WHEN USING THE LIFTER
If during a call you are using the telephone handset and want to switch to the headset, press the
Headset Button (2) or Talk Button (19) once (Headset Indicator (1) and Talk Indicator (20) will both
illuminate). The Lifter will raise and you will be able to continue the call using your headset.
Replace the handset on the Lifter. When the call is finished press the Headset Button (2) or Talk
Button (19) once. The Lifter will return the handset to the on-hook position.
