  • This module has a large display and 10-button keypad.
  • To solve this module, follow the steps below.

Step 1: Determine the Field

  • Use the table below to get a field.
  • This field will be used in Step 2 and 3.

Step 2: Decrypt Displayed Digits

  • Split the encrypted numbers on the display into 5 number pairs in reading order.
  • Convert each number to a digit using the field from Step 1. Each number's corresponding digit can be found in the cell at the number's position, counting in reading order (top-left is cell 1).
  • Each pair will make a new two-digit number.
  • Modulo each two-digit number by 26 and convert them into letters using A1Z26. This will form a keyword

Step 3: Inputting

  • Find the keyword's corresponding pixel art in the table below.
  • Start with the top left cell in the pixel art. If that cell is black, press the corresponding digit in the same position in field 1. If the cell is white, do nothing.
  • Repeat this for all cells in the pixel art in reading order.
