Scanning Modes
The reader can operate in one of several scanning modes:
Trigger Single — 
When the trigger is pulled, scanning is activated 
until one of the following occurs:
- a programmable duration
1
 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 pro-
grammable duration
1
 has elapsed.
Trigger Hold Multiple  — 
When the trigger is pulled, scanning 
starts and the product scans until the trigger is released or a pro-
grammable duration
1
 has elapsed. Reading a label does not disable 
scanning. Double Read Timeout
2
 prevents undesired multiple 
reads while in this mode.
Trigger Pulse Multiple — 
When the trigger is pulled and released, 
scanning is activated until programmable duration
1
 has elapsed or 
the trigger has been pulled again to transition to another state. 
Double Read Timeout
2
 prevents undesired multiple reads while in 
this mode.
1. See the Product Reference Guide (PRG) for additional programmable fea-
tures, in this case: Scanning Active Time.
2. Double Read Timeout is also programmed using the PRG.
