On the Subject of Double Arrows

It’s enough to get you to the boiling point.
Garbage. This was clearly wired up by imbeciles. ★☆☆☆☆

Original Manual

On the module are eight directional buttons pointing in four directions, a black reset button, and a display screen in the center.

Initially on this display is a two digit number; this is the starting position in the grid below.

Each of the eight buttons will move your position in the grid in one of the four cardinal directions, these directions may not necessarily be the directions the buttons themselves are pointing.

However:

  • Inner buttons will always move 1 space.
  • Outer buttons will always move 2 spaces.

The eight buttons can be pressed once each to change the displayed number.
Due to a fault, once a button has been pressed, the display will only show the digital root of the new position.

Once all eight of the buttons have been pressed once, you will have returned to your starting position and the screen will turn off.

From this point:

  • If there is an even number of batteries on the bomb, move to the position that is one higher than your current position, unless you are at position 81, in which case move to position 01.
  • Otherwise, move to the position that is one lower than your current position, unless you are at position 01, in which case move to position 81.

The module is solved when the tenth valid move is made.

Your position will not change if an invalid move is made.

The Massive Optimization Table

Positions in the table provided contain their digital root in parentheses "()". Blue marked positions are incrementally adjacent to the current positions; red marked positions are detrimentally adjacent to the current positions. 01 is considered to be incrementally adjacent to 81; and 81 is detrimentally adjacent to 01. Directions are abbreviated by a single character.
