Distant electronic device (6)
I believe the answer is:
remote
'distant' is the definition.
(similar in meaning)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for remote that I've seen before include "Hand-held TV control" , "device used by couch potato?" , "Far way like meteor" , "Distant (from civilisation?)" , "rather aloof" .)
