scratch at the panel。
〃We should be doing this ourselves；〃 Ted said。
〃Use suction；〃 Barnes said。
Another arm extended out； with a rubber sucker。 〃Ah； the plumber's friend；〃 Ted said disdainfully。
As they watched； the sucker attached to the panel； flattened。 Then； with a click； the panel lifted open。
〃At last！〃
〃I can't see。 。。。〃
The view inside the panel was blurred； out of focus。 They could distinguish what appeared to be a series of colored round metal protrusions； red； yellow； and blue。 There were also intricate black…and…white symbols above the knobs。
〃Look；〃 Ted said； 〃red； blue； yellow。 Primary colors。 This is a very big break。〃
〃Why？〃 Norman said。
〃Because it suggests that the aliens have the same sensory equipment that we do…they may see the universe the same ＇＇65＇＇ way； visually； in the same colors； utilizing the same part of the electromagnetic spectrum。 That's going to help immeasurably in making contact with them。 And those black…and…white markings 。。。 that must be some of their writing！ Can you imagine！ Alien writing！〃 He smiled enthusiastically。 〃This is a great moment；〃 he said。 〃I feel truly privileged to be here。〃
〃Focus；〃 Barnes called。 〃Focusing now； sir。〃
The image became even more blurred。 〃No； the other way。〃
〃Yes Sir。 Focusing now。〃
The image changed； slowly resolved into sharp focus。 〃Uh…oh；〃 Ted said； staring at the screen。
They now saw that the blurred knobs were actually three colored buttons： yellow； red； and blue。 The buttons were each an inch in diameter and had knurled or machined edges。 The symbols above the buttons resolved sharply into a series of neatly stenciled labels。
From left to right the labels read： 〃Emergency Ready；〃
