Please choose the correct ending to complete the given sentence: Computers and Electronics: [header] How to scan with your tablet computer [title] Get yourself a way to elevate and hold your device at a steady height. [step] Technically, you can just hold it and do it, but if you are going to scan more than a couple of items, you want it held for you. Here is a box that is about 13-14 inches (33.0-35.6 cm) deep.

Ending1: [title] Find a scanner wire long enough to provide extended viewing. [step] Be sure to slide the scanner wire up from the bottom of the scanner so it is not going to obstruct your viewing space. Ending2: It should have a drop door, preferably one that fits with height, to slide up and down. Add your tablet to that box with your tablet, and you'll find it significantly higher. Ending3: [title] Remove at least one side of the box. [step] You will need to light up what you are scanning. Ending4: Make sure to get it up to the proper height. [title] Use a card reader as an alternative.
