Does the little diagram show different pictures for different countries ?.
Take a photograph of the diagrams, Usually they show wire links connecting maybe pins 1 and 2 (or another configuration).

close the 2 valves, then drain from bottom by loosening nut closest to the rad.
Then disconnect same nuts and remove radiator from the brackets.
refill by using the filling loop near or fitted on boiler.

Do you have any local taxi companies reasonably close to your home ?.
Do you have any mobile phone masts close by, these produce interference known as TETRA.

Is it not connected using an s-video cable ?.(little round 5/6 pin)
Then you use your FN key with maybe F10/F11 to flick from laptop screen to external display.

Ive never heard of any harm being done.
As long as you have a fully serviced boiler with protective chemicals any towel rad will be fine.
ps My little myson towel warmer is perfect on a vented system.
