This is one of the most popular questions Actall gets and is really simple,  Once you have changed the battery in the transmitter, make sure that you depress the white reset button inside the casing (just above the battery holder.  A thin screwdriver or the cap off of a generic pen will work fine.  

At that point, go to the PMT programming screen in Crisis Controller (Device Mgmt > PMTs), choose the correct PMT id and click 'program'.  The Programming screen will open and prompt you to attach the programming cable.  Find the cable, plug it in to the PMT and the device should program correctly.  The screen will tell you when programming is complete!
