Setting up mix mode

Hello Everyone,
I would like to set up a mix mode on my current survey.
I already set up the CAWI mode with the parameters; email: empty, password: specified, quantity: -1, and it works well.

My questions are:

  1. How can I set up the web interviewing - interviewers conduct interviews using a web interface (without a tablet)?

  2. As soon as possible I want to set up the CAPI mode. I will have CAPI, CAWI and web interviewing running on the same time.

Note: My survey do not have the identifying questions and it do not have sample.

Can someone help me how to set up this mixed mode?
Thanks in advance,
