The Automatic Trigger and Presentation Modes are referred to as “hands free” 
modes.  If the scanner’s trigger is pulled when using a hands free mode, the 
scanner changes to manual trigger mode.  You can set the time the scanner 
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 scanner 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 scanner 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.

Reread Delay only works when in automatic trigger mode (see 

If you want to set your own length for the reread delay, scan the bar code below, 
then set the delay (from 0-30,000 milliseconds) by scanning digits from the inside 
back cover, then scanning 

Save.
