Plantronics Interface

The HL1 handset lifter is used with the CA20 DECT adapter to provide automatic control of the telephone hook switch when a user receives a call remotely from their desk. When CA20 is used with the lifter unit, the user is alerted to an incoming call either by an audible tone in the headset or by a ringing tone from the remote pack. A small microphone, attached close to the ringer on the phone, picks up the ringing signal and a notification signal is transmitted to the remote pack. When this occurs, pressing the activation button on the remote pack takes the phone off hook and the call can be taken through the headset. On completion of the call, the same button is pressed again to return the handset to the on-hook state. The mechanical arm is adjustable to suit most telephone handset styles.
