Scanning Features

Product Reference Guide

Selects the scan operating mode for the reader. Selections are:

When the trigger is pulled, scanning is activated until one of the following 

occurs:

-

Scanning Active Time

 has elapsed

- a label has been read
- the trigger is released

This mode is associated with typical handheld reader operation: when the trigger is pulled, 
scanning starts and the product scans until the trigger is released, or a label is read, or the 
maximum

Scanning Active Time

 has elapsed.

When the trigger is pulled, scanning starts and the product scans until 

the trigger is released or 

Scanning Active Time

 has elapsed. Reading a label does not disable 

scanning. 

Double Read Timeout

 prevents undesired multiple reads of the same label while in this 

mode.

When the trigger is pulled, continuous scanning is activated until 

Scanning Active Time

 has elapsed or the trigger has been released and pulled again. 

Double Read 

Timeout

1 prevents undesired multiple reads of the same label while in this mode.

The reader flashes

 on and off regardless of the trigger status. Flash rate is controlled 

by 

Flash On Time

 and 

Flash Off Time

. When Flash is ON the imager reads continuously; when 

Flash is OFF scanning is deactivated. 

No trigger pull is required to read a barcode. Scanning is continually on. If the 

trigger is pulled, the reader acts as if it is in 

Trigger Single

 Mode. 

Double Read Timeout

1 prevents 

undesired multiple reads of the same label while in this mode.

No trigger pull is required to read a barcode. Scanning is turned on automatically 

when an item is placed in the reader’s field of view. If the trigger is pulled, the reader acts as if it 
in single read mode. 

Double Read Timeout

1 prevents undesired multiple reads while in this 

mode.

This mode is similar to Stand Mode, except that a trigger pull is required 

to activate the decoder.
