Narrative:

During takeoff, aural warning sounded, 'bing bing bing, takeoff, trim,' so we pwred down, notified ATC, and exited the runway. Passenger were notified. On taxiway we reverified the system as operating normally with power applications and returned for another takeoff. I reran all ground checklists, notified the flight attendant, and we were again cleared for takeoff. All the same things happened again, so we taxied to the ramp and shut down.
