Can't do talk-back with VS-100 talkshow

Hi there

We have a VS-100 and I am placing an earphone on the back of the unit in order to use talkback but can't hear anything. I know the earphone is working because I have used it with a regular FM radio earphone jack.
Any ideas on how to troubleshoot this ?

Thank you
