If you use barcode labels that contain checksum characters, you should enable the Verify Barcode
Checksums option. If you do not use barcode labels that include checksum characters or if you mix labels
containing checksum characters with labels that do not, you should turn off the Verify Barcode Checksums
option. By default, this option is turned off. 

If your library does not include a barcode scanner, the LCD displays
“N/A” next to this option. 

You can determine whether your barcode labels contain checksum characters by contacting your vendor
or by following these steps:

1. Count the number of black bars on the label. (The number will be a multiple of 5.) 

2. Divide this number by 5 to get the number of characters.

3. Subtract the number of human-readable characters on the label from the result of step 2. If 

the result is 2, the label does not include a checksum character; if the result is 3, the label 
includes a checksum character.

To set the Verify Barcode Checksums option:

1. If the security option is enabled, disable it.

2. Display the Config Menu. If necessary, press [MENU] to display the menus (or return to the 

top of the menu selections). Press the down arrow key until “Config Menu” is displayed on 
the screen, then press [ENTER]. The Baud Rate screen appears. 

3. Press the down arrow key until “Verify Barcode Checksum” displays, as shown below. This 

screen shows whether this option is enabled (1) or disabled (0). 

4. Press [ENTER]. The following screen displays.

5. Use the up or down arrow key to select “1,” which turns on the option, or select “0” to turn the 

option off. Press [ENTER]. The new setting appears on the Verify Barcode Checksums 
screen.

6. If desired, press [ESCAPE] to return to the Config Menu.
