Procedure; Aircraft
My FO (First Officer) was conducting the takeoff. While the FO was adding power I pushed auto throttle. During the roll I thought I heard my FO say something about the thrust levers; so I moved them forward a little bit. One thing I was looking at was that the auto throttle was flashing so it possibly never activated. During initial climb my FO noticed that we were in reserve thrust and we set GA and re engaged AT. After that we continued the flight as planned without further complications.My FO later recalled seeing an EICAS message with 'TLA' on it. But we did not get a 'ENG TLA NOT TOGA' caution; so I'm not sure what that message could have been.During the set up for the performance we first set it up for anti-ice off; then I set the trim and pushed the GA button per the flow. We noticed that the thrust setting was wrong and found that we had automatically gotten numbers for engine a/i on. This was because of the temperature was between 5-10 C even though the sky was clear. We changed it and the numbers were right. Then I might not have pressed GA again which might have been why it did not activate. Another reason could have been that I pushed the button while my FO was adding power; but I think it is unlikely because it should still work from my experience.
During engine #1 start; there was a hard power transfer that turned off all of the screens momentarily; display a list of EICAS messages; and then transferred power to engine #1. Engine #2 was started without incident. An MCDU message stated CHECK TO DATA. We reviewed the MCDU and taxied for departure. During the transfer of controls the PF/FO called for the TOGA button to be pressed as the TO was not displayed in the flight mode panel on the PFD. AT were engaged and takeoff thrust setting was confirmed by both pilots.On departure prior to the after takeoff checklist there was and EICAS message stating THRUST LEVERS NOT IN TOGA. We acknowledged the caution message; pilot flying confirmed RSV thrust; and pulled the power back to the takeoff detent. The power was only shortly in the RSV.I definitely learned to double check information after an anomaly on start or part way through flows. I didn't reconfirm all before start items after the weird power transfer. I think we dealt with the TL NOT IN TOGA message well but I am unsure of why they were not in TOGA.
EMB-175 flight crew reported a Thrust Lever Angle (TLA) EICAS message on takeoff and continued the takeoff with no other difficulties.
