The Draw Tite Activator II Brake Controller part # 5500 will have a decimal point if it does not detect a trailer connected. It will display a number like 2.0 if the controller is activated and sending voltage to the brake assemblies. This number will vary as the voltage increases and decreases. The sync adjustment display will show a number while the sync is being adjusted like 2 o.

You can also see OL or ER if there is an overload or error.

I attached installation instructions for you to check out as well. For initial setup instructions check out the section labeled Setup.
