After short pause, signal recovery (6)
I believe the answer is:
rescue
'recovery' is the definition.
(rescue is a kind of recovery)
'after short pause signal' is the wordplay.
'after' is a charade indicator (letters next to each other).
'short' means to remove the last letter.
'pause' becomes 'rest' (resting is a kind of pausing).
'signal' becomes 'cue' (I've seen this before).
'rest' with its final letter taken off is 'res'.
'res' put next to 'cue' is 'RESCUE'.
(Other definitions for rescue that I've seen before include "delivery" , "Extricate" , "Set free from harm and evil" , "Pull from danger" , "liberation" .)
