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.
