Tag Function  Indication 
Save and Reset 
This tag causes the 7893 to save and 
start using the programming data. It is 
used in the Base Programming State. 
LED Status Indicator flashes red 
twice. 
Short beep as soon as tag is read—
Good Read tone. 
If Voice is enabled, a short beep 
sounds and resets the scanner. 
Abort 
If this tag is scanned in the Base 
Programming State, programming is 
terminated and no previously entered 
parameters are saved. 
LED Status Indicator flashes green 
once and returns to dim green. 
Short beep as soon as tag is read—
Good Read tone. 
If Voice is enabled, a short beep 
sounds and returns to “Program 
Mode”. 
Hex 0-Hex F 
These 16 tags enter the selections for 
each of the parameters in the Parameter 
Programming Modes. They also select 
the Parameter Programming Mode. 
Hex 0—no beep 
Hex 1 through Hex F—Beeps tag 
value. Multiples of 4 short beeps 
grouped together. Others are 
longer  
Example: Hex D is indicated by 
12 short beeps (3 sets of 4) 
followed by 1 longer beep, for a 
total of 13. 
Note:  In programming tag 
sequence, no beep for the second 
Hex tag; one short beep (different 
frequency from the Good Read 
Tone) after the last Hex tag. 
If Voice is enabled, “0” through 
“F” is spoken and no beep sounds.
Using the Programming Worksheets 
The Programming Worksheets provide a convenient method of defining your 7893 program 
before loading it into the scanner. Each worksheet relates to a specific programming mode. 
Enter your selections and changes on the Worksheets. Save this information for future use 
should it be necessary to re-enter this program. 
Most of the programming options have defaults that are determined at the factory. A bolded 
box around an entry selection specifies it as the default value. Scanning the Default tag as the 
first tag after applying power to the 7893 sets the parameters to these values. The scanner also 
indicates via beeps the Default setting. 
Enter the program into your scanner by scanning the proper sequence of programming tags 
found in the NCR Scanner Programming Tags (BST0-2121-74). Following are the three major 
steps to programming your scanner.
