C/K 1-3
D 1-4
E 1-5
F 2-1
G 2-2
H 2-3
I 2-4
J 2-5
L 3-1
M 3-2
N 3-3

R 4-2
S 4-3
T 4-4
U 4-5
V 5-1
W 5-2
X 5-3
Y 5-4
Z 5-5

Each pair gives the row and column. C and K share one square; X marks the end of a sentence.

Try encoding F (21), Y (54) or the whole word ESCAPE. Then type a code into the second box to decode it.
