Usually, unless they were treated a bit roughly, they should not need to be mastered. It's still recommended, of course.
To move the robot without the X11, go into a usergroup >= Expert and then activate the Start-Up mode. I believe it's in Startup/Service (but no promises, I'm not at the robot at the moment).
In startup mode you can only operate the robot in T1, i.e. you need to keep the button on the back pressed, even for programs, and the speed is limited.
If there is a plastic bag with 4 blue wires included, you may also need to build that plug, which provides power to the internal Beckhoff EK1100 coupler. You just connect the internal power supply with the internal power connection, unless you want an external 24V power supply. I'm at the airport right now so I cannot give you the X-something ID of the plug - I believe it's X55, though.
Finally, if you are doing the startup yourself, don't forget to plug in the battery. Inside the cabinet there will be one loose cable, which will fortunately only fits into a single plug next to it.
Best,
Johannes
