Tutorial #2: AT P/RST comes on

Was following along Tutorial #2, and everything went according to what's written. However, when I came to page 0.00.79 to set the trim, I noticed the AT P/RST light came on (above the ND). The QRH tells me to control thrust manually (the engines aren't on yet) or reengage the AT. Whenever I do reengage the AT, the switch goes back to the off position and the light comes on again.

What's the correct procedure to fix this?

Ah, nvm, solved it.

Earlier in the Tutorial, it tells you to press F1 to make sure the throttle is at idle. If you do that too long, it goes a little bit into Thrust Reverse. That makes the AT disconnect.
