Basic Phone Features

Your telephone is equipped with a speakerphone that lets you 
converse “hands free” without having to use the handset. The 
speakerphone also allows others in the room to listen and 
participate in a telephone conversation. 

If you answered or initiated a call using the handset, you can switch 
to using the speakerphone by pressing the 

 button. This 

deactivates the handset. You can leave the handset offhook, or 
hang it up.  If you lift the handset again, the speakerphone is 
disabled automatically.

While the speakerphone is active, the LCD screen on the phone 
shows a speaker icon.

Press the 

 button.

Press the blinking line button.

Press the 

 button on your phone.

When the speakerphone is on, press the plus (+) and minus (-) 
buttons beneath the dial pad to adjust the speakerphone volume. 
The speakerphone microphone is optimized for speaking within 3 
feet from in front of the microphone.
