If the ENTER button is held down for 2 seconds, the number you have placed in
the cursor cell receives the status of a "given" number. If you hold down ENTER
again for 2 seconds, the number no longer has this status.
<< - Deletes the last number you inserted. If you press this button repeatedly
or hold it down, the machine takes back a whole series of numbers (up to a
maximum of 51 numbers).
>> - When you have just used the << button, a press on >> replaces the last
number you took back. Pressing >> repeatedly or holding it down, replaces a
whole series of numbers.
LEGAL: Displays all the numbers that you can legally insert in the cursor
cell (or can legally overwrite on the number already there). These numbers
appear in the top line of the LCD. This feature remains active until you switch it
off by pressing LEGAL again (or until you use the "notepad" feature, start a new
puzzle or switch off the machine).
NOTEPAD: Allows you to make a note of "candidate numbers" (numbers
that you think might be correct) for one or more cells:
1. Press NOTEPAD.
2. Unless the cursor cell contains a "given" or "locked" number, the numbers 1-
9 appear in the top line.
3. To mark a number as a "candidate" for the cursor cell, you insert a "box"
around that number by pressing its number button. Pressing the same
number button again removes the box.
4. You may move the cursor to any other cell, so you can see its "candidates"
and change them if you wish.
5. When you are ready, press NOTEPAD again and carry on solving the
puzzle.
