Intermec 4800 User Guide

Presentation Sensitivity is a numeric range that increases or decreases the 
imager's reaction time to bar code presentation.  To set the sensitivity, scan the 
Sensitivity bar code, then scan the degree of sensitivity (from 0-20) from the 
inside back cover, and 

Save.  0 is the most sensitive setting, and 20 is the least 

sensitive.  

Default = 1.

The Scan Stand and Presentation Modes are referred to as “hands free” modes.  
If the imager’s trigger is pulled when using a hands free mode, the imager 
changes to manual trigger mode.  You can set the time the imager should remain 
in manual trigger mode by setting the Hands Free Time-Out.  Once the time-out 
value is reached, (if there have been no further trigger pulls) the imager reverts 
to the original hands free mode.  

Scan the 

Hands Free Time-Out bar code, then scan the time-out duration (from 

0-300,000 milliseconds) from the inside back cover, and 

Save.   Default = 5,000 

ms.

This sets the time period before the imager can read the 

same bar code a second 

time.  Setting a reread delay protects against accidental rereads of the same bar 
code.  Longer delays are effective in minimizing accidental rereads at POS (point 
of sale).  Use shorter delays in applications where repetitive bar code scanning 
is required.  

Default = Medium.
