is turned to the "'OFF position the pause lock will automatically disengage itself

A 4 digit revolution counter with push button reset enables quick and easy location of recorded items.

To enable one to use from 3 reels up to the maximum size of 8}" the deck is fitted with a tape tension
adjustable from the top of the deck.

An auto-stop which operates in the case of tape breakage or the tape running out is now a standard feature
