Escaping The Broken Time-Machine

Alexis is time-traveling inside an elevator-sized time machine into December 14th, 1977 from June 2nd, 2700 when the time machine halted, abruptly.

Alex started tensing. She rummaged through her bag, trying to find her inter-stellar communication device, but, mysteriously, it was not there. Instead, she only found a couple of coins, a wrench, a hairbrush, a screwdriver, and a pack of dry cells. She looked around and saw fire hydrant, a couple of buttons, and something like a battery holder unit.

Alex was in deep thinking when suddenly, there was a large beep, and following the beep a scratchy voice muttered a long list of letters, in this order:

O S M O W D I T J D C M H M B J M D A O T J M T D E J R O I J E D S

A few seconds later, a sweet woman’s voice shouted what sounded like:

Bctoeor Amy Cebrmdee Uljy ….Scrambled….Remove….Letters….First….Voice….

What should Alex do?
