USING THE HEADSET
Making and answering calls 
To make a call
Dial from your mobile phone, and the call will automatically transfer to the 
headset. If your phone has voice-activated dialing, press the Bluetooth
® 
function button and wait for the phone voice prompts. 
To activate voice dialing (if your phone provides this feature) 
When there are no active or incoming calls, briefly press the Bluetooth function 
button.
To answer a call
Briefly press the Bluetooth function button. You should hear a short beep in the 
headphones before you hear the incoming call. 
To end a call
Briefly press the Bluetooth function button. You should hear two short beeps in 
the headphones to indicate that the call has been ended. 
To reject an incoming call
Press the Bluetooth function button for three seconds. 
Note: To avoid putting the control module into pairing mode, do not press the 
Bluetooth function button for more than five seconds.
To redial the last number
When there are no active or incoming calls, press the Bluetooth function button 
twice in quick succession.
Note: Whether or not you can reject an incoming call, activate voice dialing, or 
redial the last number, depends on the capabilities of your phone. Please 
check your phone user guide for further details.
To transfer the audio to the mobile phone
When you are on a call, press the Bluetooth function button for three to four 
seconds. This transfers the audio to the mobile phone handset while the 
Bluetooth wireless technology connection remains active.
Note: If you are on a call and unplugged from an intercom, the headset will allow 
you to complete your call, then it will turn off approximately three seconds after the 
call is terminated. To use the headset when unplugged from the intercom to listen 
to auxiliary input audio, or as a standalone Bluetooth technology headset to make 
or receive calls, we recommend you disable the Auto Off feature for uninterrupted 
functionality.
