Emergency Zeroize Steps require which action on Z1 and Z2?

• A. Simultaneous double press
• B. Single press
• C. Triple press
• D. Hold for five seconds

Answer: (A)

Emergency zeroize is a safeguard to erase memory and sensitive data, so it’s designed to be triggered only by a deliberate, unmistakable action. The required method—pressing both Z1 and Z2 together, and repeating that simultaneous action (a double press)—gives a strong, intentional signal that the operator truly wants to wipe the memory. This dual-switch, two-step sequence protects against accidental activations from a single button press, glove snag, or momentary contact in rough conditions, by demanding that both switches be actuated at the same time twice in quick succession. The other options don’t provide that same level of certainty: a lone press could happen accidentally, holding for five seconds is slower and still potential for misinterpretation, and a triple press isn’t the designed, standard method for this function.
