Clothing Clip 

The clothing clip keeps the headset 
properly seated and free from the 
cord’s weight. Attach the 
clothing clip at a 
comfortable level.

Quick Disconnect

  

Connector

This feature allows you 
to place a call on hold 
and move away from 
the phone without 
removing the headset. 
When you separate 
the Quick Disconnect, 
you place an ongoing 
conversation on hold.
Before using your headset, join 
the Quick Disconnect to the mating 
connector of the modular adapter cable.
To put your call on hold, grasp Quick 
Disconnect, as shown, and pull straight 
apart. To resume your conversation, 
reconnect the two halves.

The Convertible Process

(171 and 171N models only)

Over-the-ear: 
To put on 
headset, move 
earloop away 
from receiver and 
place earloop over 
your ear. The over-the-ear 
configuration allows further 
control by adjusting the 
flexible earloop as shown.  

Over-the-head: Adjust 
headband length so 
stabilizer bars rest above 
your ears. If necessary, to 
increase or decrease tension 
on your head, bend the 
metal part of headband 
inward or outward for 
desired comfort. Push 
receiver close to your ear until 
it feels comfortable and you 
can hear the sound from the telephone clearly. 

In both configurations: The end of the boom should 
be placed a distance of two fingers from the corner 
of your mouth.
