During the Activation Phase, each of the 5 registers on your player boards are activated in order. Each register is resolved by following these 3 steps in order:
(A) Programming Card Activation;
(B) Board Element and Robot Weapon Activation; and
(C) End of Register Activation.
Repeat steps A, B, and C for the remaining registers. Remember, after all players have activated their programming cards for a single register, Board Elements activate, robots fire their weapons, and End of Register effects happen.
