Distant handset (6)
I believe the answer is:
remote
I believe this clue is a double definition.
'distant' is the first definition.
(I know that distant can be written as remote)
'handset' is the second definition.
(I know that handset can be written as remote)
(Other definitions for remote that I've seen before include "TV control device" , "station selector?" , "Device for controlling apparatus from a distance" , "Detached" , "'Distant, out-of-the-way (6)'" .)
