Situation #3: (A319 Captain's Report)
■ During the initial part of the takeoff roll, at approximately 40 knots, three or four faint beeps were heard. The source of the beeps was unknown. There were no ECAM messages and no lights illuminated anywhere in the cockpit that would indicate an abnormality.

Situation #3: (A319 Captain's Report)
The Reporter's Action:
■ The takeoff was rejected at about 50 KTS. Upon clearing the runway, I realized that the beeps were from my phone. It was in the Airplane Mode, however, when the low battery warning sounds it makes a beeping noise. The battery charge was low.
