User gets wrong signals (8)
I believe the answer is:
gestures
'signals' is the definition.
(gesture is a kind of signal)
'user gets wrong' is the wordplay.
'wrong' indicates an anagram.
'user'+'gets'='usergets'
'usergets' with letters rearranged gives 'GESTURES'.
(Other definitions for gestures that I've seen before include "Make signs with hand movements" , "Expressive motions" , "waves" , "Movements to express something" , "Expressive movements" .)
