Narrative:
We added power; armed the ctot/apr [constant torque on takeoff/automatic power reserve functions] and rolled down the runway. At around 100 KIAS we received a configuration warning at which time we executed a rejected takeoff and exited the runway.we immediately discovered the problem; the condition levers [cls] had vibrated just below their acceptable position and caused the warning even though the friction lock was firmly in place. We started a timer; taxied to the ramp; and consulted with maintenance control; dispatch and the chief pilot. We determined that it was not a high energy abort because; according to our manuals; we used reverse and only normal braking and were only required to wait 15 minutes for brake cooling before attempting another takeoff. However; our duty manager instructed us to write up the event and contract maintenance came out to the aircraft and determined the condition levers had 'spring back'; suggested that a re-rig be done at some point and signed off the aborted takeoff.
