Final answer:
To change the illumination options on an X26, both putting the safety switch in the down (SAFE) position and depressing the illumination button are required steps.
Step-by-step explanation:
The correct answer is option d) Both a & b. To change the illumination options on the X26, a model often referred to in the context of Tasers or law enforcement equipment, you must first ensure the safety of the device by putting the safety switch in the down (SAFE) position. This action prevents accidental discharge of the device while you make changes to the settings. After the safety switch is set to SAFE, you then depress the illumination button to cycle through or select the desired illumination setting. This process is important to prevent any unintended harm while handling the X26.
The safety switch is located on the side of the X26 and has two positions: up for armed and down for safe. By putting the safety switch in the down position and then depressing the illumination button, you can change the illumination options on the X26.
