Тема: Problem installing Expansion 16STL

Please help me! I installed the expansion unit 16SLT for Panasonic KX-TD1232. But unfortunatelly it doesn’t work at all. All the extension on that port don’t have any signal. What should I do to make it works! In program [600] I should put : A1;D;D, but the incorrect tone is beeping! Where is the problem? If somebody can help me - I’ll be very glad! Thanks in advance.
