LIME North Apron ground signals
 

Hi all, working on a scenery for simulator, I found some difficult to identify a ground signal found in the north apron of LIME airport. I attach a little jpg of th earea in which is drawn the signal, printed using SAS PLANET software. The signal with white background has a no parking circle (red and blu) but I cannot read what is written in the white area. I think there are two words. Using google earth there is the possibility to suppose that one of the two words could be ONLY, maybe the other could be RAMP but it is only a guess....
Is there anyone that could help me, maybe someone who work on that apron or who has a more detailed image.
Thanks in advance
