PInterwrite PRS RFRS RF was the first assessment device to incorporate an LCD display and all question types.  Powered by three AAA batteries and utilizing the Cypress Semiconductor Direct Sequence Spread Spectrum (DSSS) wireless technology, PRS RF offered great new capabilities to the market and could be configured in an open mode, closed mode or loaner mode, supporting applications in Higher Ed, K-12 and corporate training applications.

PRS RF incorporated a unique scanning technique to search for classes when initially turned on.  The user would then be prompted for the appropriate class to join, depending on the mode of operation.  This allowed a dynamic utilization of frequencies on a campus and avoided having the IT Department set and allocate channels for specific classrooms.
