Called with electronic compass (5)
I believe the answer is:
range
'compass' is the definition.
(I've seen this before)
'called with electronic' is the wordplay.
'called' becomes 'rang' ('ring' can be a synonym of 'call').
'with' means one lot of letters go next to another.
'electronic' becomes 'e' (as in e-mail or e-books).
'rang'+'e'='RANGE'
(Other definitions for range that I've seen before include "Place to practise driving" , "Extent; line of mountains" , "Ramble" , "Old song: ''Home on the . . . . .''" , "Array" .)
