Narrative:

While on visual approach to runway 20 cha; approximately 2-3 miles from hixon FAF while leveling at 2;100 ft crossing altitude; received egpws pull up warning. As pilot flying I immediately disconnected the autopilot; raised the nose and began to advance the throttles when the warning ceased. Both I and the first officer had terrain selected on nav display and rate of descent did not seem excessive. Airspeed was approximately 175 while slowing to 170. High terrain in area to west was behind aircraft. Light conditions were good as it was right at dawn and visibility was clear. I could see the airport. After the warning ceased we intercepted the localizer just prior to hixon; slightly high; but able to continue normal visual approach and landing. I believe the conditions were 'day VFR' and the warning was in error. Occurrence was debriefed between myself and the first officer and both of us thought it was a normal approach. Logbook entry made and maintenance debriefed. I could have asked for vectors to final and accepted the visual later or possibly slowed the rate of descent prior to hixon.

Title: B757-200 flight crew experiences an EGPWS terrain warning turning right base for Runway 20 at CHA and leveling at 2;100 FT. At the first addition of thrust the warning ceases and the approach is continued to landing. Day light VMC prevailed at the time.
