On the Subject of Third Base

This module is identical to Who’s On First, except with four characters on each button instead of confusing words and phrases. This should be easy... right?

1. Read the display and use step 1 to determine which button label to read.
2. Using this button label, use step 2 determine which button to push.
3. Repeat until the module has been disarmed.

Step 1:

Based on the display, read the label of a particular button and proceed to step 2:

SXHN	X9HI	Z8IX	6O8I	ZHOX	S89H
NXO8	XI8Z	NHXS	HZN9	IS9H	I8O9
8OXN	8I99	H68S	XZNS	SZN6	66I8
XOHZ	X6IS	9NZS	8NSZ	6NZH	IH6X
	H6SI	SNZX	SI9X	ZSN8

Step 2:

Using the label from step 1, push the first button that appears in its corresponding list:
