## Discrepancy

ON TAKEOFF ROLL, THE CREW NOTICED THAT THERE WAS A LOSS OF COMMUNICATION / AVIONICS ISSUE BETWEEN THE CAPTAIN AND THE FIRST OFFICER.  REPORTED TO THE DISPATCHER THAT THEY DID A LOW ENERGY ABORTED TAKEOFF AND WERE RETURNING TO THE GATE FOR MAINTENANCE PROCEDURES.  REMOVED AND REPLACED REU, OPS CHECKS GOOD.
