INSTALL AUTOMATIC HANDSET LIFTER  
4
Why use a handset lifter? The lifter greatly simplifies using  
a headset with your desk phone. It lets you answer and  
end calls without being near your phone.  
The HL10 Automatic Handset lifter is included with certain CS55 configurations and is  
also available separately.  
A. Connect Handset Lifter power cord to Headset Base  
1. Verify that the base-to-desk phone cable is connected to the handset port of the desk  
phone, and not the headset port (Refer to Step 2, Configuration A).  
2. FIRMLY PRESS the Handset Lifter power cord into the RED labeled port to ensure a  
complete connection.

Set Speaking Volume  
While on a call, set the Speaking Volume Switch to the best setting for the listener (a paper  
clip or pen tip can help). Too high a setting can produce an uncomfortable echo for you  
and distorted sound for your listeners. You will be able to make minor adjustments to  
speaking volume while on a call using the Speaking Volume Control on the back of the  
base.

To set the IntelliStand Feature  
The CS55 IntelliStand feature allows you to choose how to activate your headset when answering  
or making a call. Consider how you’ll use your headset to determine the best setting for you.  
IntelliStand Switch  
In the UP position, answer, make or end a call by pressing the Call Control Button on your  
headset. Choose the UP position if you plan to wear your headset most of the time.  
In the DOWN position, calls are initiated, or answered by taking the headset out of the stand.  
A short delay gives you time to put the headset on. Choose the down position if you think you’ll  
wear your headset ONLY while on calls. In the DOWN position you can still answer, end or make a  
call by pressing the Call Control Button.  
In either the up or down position, placing the headset in charging cradle will end the call.  
If the sound quality is poor or background noise is evident after these adjustments  
readjust the configuration dial for better quality.

If the distortion is still present, lower the volume us-  
ing the Listen Volume Button on the headset.
