2-6  Chapter 2: Product Information 
Operator Interface 
Interface between the operator and the 7893 is very minimal. Messages are sent from the 7893 
to the operator through LED status indicator, audio tones, and voice messages. 
Voice Messages 
If the 7893 has voice enabled, certain mode changes and error conditions are alerted by 
synthesized voice messages. These messages give either the changed mode or the error 
message with the suggested corrective action. Voice is enabled and disabled in the 
Miscellaneous Parameter program. 
Note:  By default, Voice is ON. 
LED Status Indicator 
The LED Status Indicator is an intuitive feature of the 7893. It provides visual confirmation for 
scanning items using different colors— which is especially ideal for hearing–impaired cashiers 
and enables a quieter front end. 
The LED Status Indicator is also useful in diagnosing problems with the 7893. Using a color 
coded LED, the user may quickly identify problems – thus effectively decreasing downtime 
and enhancing productivity.

Motion Detector 
The Motion Detector feature prolongs the life of the 7893. This is located inside the scanner 
window; it turns off components of the 7893 after an extended period of non–activity. The 
default non–active time is fifteen (15) minutes, but can be changed by programming. An item 
passing in front of the Motion Detector causes the 7893 to turn on. This movement is the 
normal item scanning movement.
