You can conference up to three additional headsets to a call in progress. 
Join a conference call
While in an active link between the primary headset and the base (on a call), place the guest 
headset into the primary user’s charging cradle (this connects the headset to the base). The 
base subscription LED will begin flashing. After a few moments, the primary user will hear 
a triple tone in their headset indicating the guest headset wishes to join the call. Within ten 
seconds of hearing the triple tone, press the primary headset’s call button to accept the guest 
headset. If the process fails or times out because the button was not pressed within ten 
seconds the guest subscription is terminated and the guest will hear an error tone in their 
headset.
To connect a guest headset that is of a different variety to the primary headset, press the base 
subscription button while the base has an active link. Next, press the guest headset volume 
up button until the indicator light turns on. The base subscription LED will begin flashing and 
the primary user will hear a triple tone in their headset indicating the guest headset wishes 
to join the call. Within ten seconds of hearing the triple tone, press the primary headset’s call 
button to accept the guest headset. If the process fails or times out because the button was 
not pressed within ten seconds the guest subscription is terminated and the guest will hear an 
error tone in their headset.
NOTE 
Headsets in a conference maintain independent mute controls. The base only indicates the 
primary user’s mute state. 
Exit a conference call
Guests’ headsets can remain as guests through multiple calls. To remove a guest headset, press 
the guest headset’s call button or dock the primary user’s headset in the charging cradle. A 
single tone in the master headset will be heard as each guest leaves the call.
NOTE 
The user of the primary headset in a multiple headset conference scenario may hear 
additional tones (triple tones) in their headset and see the subscription LED on the base flash as 
guest headsets join the call. These additional tones and flashing LED indicate that the guest headset 
has a different version of firmware to the primary headset, but can still be used for conferencing.
