CREATING CODED MESSAGES
You can save secret code words in the RECORDER and give it to someone
else to listen to later on to help unravel coded messages. We can use this
to send special Key Words to help your fellow Spies work out coded
messages. Keeping information safe from people who are not supposed to
see it is more important today than it ever was because we send so much
more information. Telephone calls and e-mails can be intercepted so we
need to be able to code the information to keep it safe.

A SIMPLE CODE
Step 1
Make up your secret message. Let’s say that your message is “Tonight at
ten in the house”
Step 2
To make a converter to code the message, first write out a normal alphabet
(in small letters). Underneath this, write out another alphabet (in CAPITALS)
but shifted along by 6 letters as below. Look for the letters of your message
in the top row, then below each letter find the code letter to use instead.
Step 3
Write down your message without any spaces between the words. Write
underneath the code letters for each letter reading them off your code
converter above.
Step 4
Write down the coded message only on a small piece of paper and speak
and record into the RECORDER block the special number “ 6 ” ( the number
of letters you shifted the alphabet along ) to allow your friend to decode the
message. Remember to put the slider switch to Play
