Which sequence is used to arm the device in Arm Mode?

• A. Left, Right, Up
• B. Down, Left, Right
• C. Left, Left, Down
• D. Up, Right, Up

Answer: (C)

Arming a device in Arm Mode is all about requiring a deliberate, non-slip input pattern so it won’t activate by accident. A design that is safer uses a buildup action—such as repeating the same input—together with a final, distinct input to confirm intent. This makes accidental arming unlikely during normal handling while remaining something a trained operator can perform on purpose.

The option in question follows that idea: it uses a repeated input as a clear cue of intent, then a final action that confirms the arming. That combination creates a higher threshold for activation, reducing the chance of random movements triggering it.

Sequences that mix directions or lack a distinct final confirmation tend to be triggered more easily by incidental motions, making them less safe for arming procedures. Always rely on proper training and documented procedures when working with arming sequences.
