  1 headset connector, 2.5mm 3-pole mini-jack. 
 
 
 
The headset plug must have the following configuration: 
Tip: 
microphone output 
Ring: 
earphone (receiver input) 
Sleeve: 
common/ground 
 
 Headsets with the microphone positioned in front of the user’s mouth, connected to the earphone 
through a rod, tend to give more echo than earbud headsets with the microphone attached to the 
cord. TANDBERG recommends the Plantronics MX100 headset (
