Chapter 6: Special Programming  6-9 
Voice Volume 
To change the volume of the voice (speech) on the 7893, scan the following tags. 
  Program Mode, Hex 5, Hex 7, Hex 0, Save and Reset—Maximum voice volume 
  Program Mode, Hex 5, Hex 7, Hex 1, Save and Reset—High voice volume 
  Program Mode, Hex 5, Hex 7, Hex 2, Save and Reset—Medium voice volume 
  Program Mode, Hex 5, Hex 7, Hex 3, Save and Reset—Minimum voice volume 
Volume Levels 
There are eight standard volume settings in the 7893. However, there is a programming 
sequence which activates eleven. This gives the operator greater flexibility in selecting the 
appropriate volume of the Good read Tone. This parameter does not have a default value, 
however, the 7893 is shipped from the factory with this parameter disabled. The default setting 
of the 7893 is eight volume levels. 
  Enable—Program Mode, Hex 4, Hex 2, Hex 5, and Save and Reset 
  Disable—Program Mode, Hex 4, Hex 2, Hex 4, and Save and Reset 
Single Volume Adjust Bar Code 
There is a single Volume Adjustment bar code in the Programming Tag booklet, NCR Scanner 
Programming Tags (BST0–2121–74) available at www.info.ncr.com
. (The tags are also 
included in Appendix B of this document.). The volume obtained by using this bar code is 
temporary. That is, if used outside a Program Mode/Save & Reset sequence, the original 
programmed volume level will return when the scanner is power cycled. But if the Volume 
Adjustment bar code is scanned within a Program Mode/Save&Reset sequence, or the Reset 
bar code from the booklet is scanned, the volume is saved as if it had been changed by using 
Worksheet 11. 
Firmware Flashing  
Firmware flashing permits updates to be installed to the scanner firmware without replacing 
the actual chip on the Digital Board. The 7893 must be connected to a PC through an RS-232 
or USB cable. The PC must also contain the Flash Tool software utility and the new scanner 
firmware file.  The cables which can be used for flashing the 7893 are: 
  USB  
  RS-232 
Obtaining the Tools and New Firmware 
If you will be reflashing a number of scanners of varying ages, you should install the NCR 
RealPOS Scanner Flash tool for Windows. All tools and firmware for the 7893 are available on 
the NCR web site (www.ncr.com).
