Introduction 1-5
Entering Letters
To enter uppercase letters, press one of the numeric keys in Shift mode
(S appears on the status line). For example, the letters “ABC” appear on
the face of the 7 key.
1. Press Shift to enter Shift mode.
2. To enter the letter A, press 7 once; to enter B, press 7 twice; to enter
C, press 7 three times.
Press the keys quickly. If you pause too long between key presses, the
printer assumes you have entered the letter you need and the cursor
moves one space to the right.
Correcting Data Entry Errors
If you make a mistake as you enter data, you can do two things.
♦ If you have already pressed Enter at the prompt you want to correct,
press Esc, and the Format menu will reappear.
♦ If you are still at the prompt (have not pressed Enter), press Shift-
Bksp to clear the entire line and return the cursor to the left-most
position.
About Check Digits
A check digit is a character that verifies the accuracy of the bar code.
With a few exceptions described later, the digit appears in the right-most
position of the example bar codes in Chapter 3. It is not part of the data.
