Setting up a conference call

Your Zen device, together with its GSM capability, can set up a conference call of up to five (5) 
people. During a call, you can add more contacts and merge all calls into one conference call.

1.  Call a contact or dial a number. Wait for the other line to answer your call.

2.  When your call is answered, tap  

  then tap a contact or dial a number that you wish to 

include in your conference call.

3.  Tap  

  to put the two calls in a conference call.

4.  Tap  

  to add another contact, then tap  

  to merge the call to the current conference call. 

Repeat this step if you want to add more contact/s to your conference call.
