Distress signal is quiet - I can manoeuvre champion driver (5,6)
I believe the answer is:
panic button
'distress signal' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'quiet i can manoeuvre champion driver' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'manoeuvre' is an anagram indicator.
'champion driver' becomes 'button' (I have seen 'Fast driver' mean 'button' so perhaps 'driver' could also mean 'button'. I am not sure about the 'champion' bit.).
'i'+'can'='ican'
'ican' with letters rearranged gives 'anic'.
'p'+'anic'+'button'='PANIC BUTTON'
'is' is the link.
Can you help me to learn more?
(Other definitions for panic button that I've seen before include "One hit by the terrified" , "What's hit in an emergency" , "article provided to press in emergency" .)
