Scan Mode
Selects the scan operating mode for the reader. Selections are:
Trigger Single:
When the trigger is pulled, scanning is activated until one of the
following occurs:
• Scanning Active Time on page 86 has elapsed
• a label has been read
• the trigger is released
This mode is associated with typical handheld reader operation: when the trig-
ger is pulled, scanning starts and the product scans until the trigger is released,
or a label is read, or the maximum Scanning Active Time on page 86 has elapsed.
Trigger Hold Multiple :
When the trigger is pulled, scanning starts and the product
scans until the trigger is released or Scanning Active Time on page 86 has elapsed.
Reading a label does not disable scanning. Double Read Timeout on page 74 pre-
vents undesired multiple reads of the same label while in this mode.
Trigger Pulse Multiple:
When the trigger is pulled, continuous scanning is acti-
vated until Scanning Active Time on page 86 has elapsed or the trigger has been
released and pulled again. Double Read Timeout on page 74 prevents undesired
multiple reads of the same label while in this mode.
Flashing:
The reader flashes

on and off regardless of the trigger status. Flash
rate is controlled by Flash On Time on page 87 and Flash Off Time on page 88 . When
Flash is ON the reader reads continuously. When Flash is OFF scanning is deac-
tivated.
Always On:
No trigger pull is required to read a bar code. Scanning is continually
on. Double Read Timeout on page 74 prevents undesired multiple reads while in
this mode.

Stand Mode:
No trigger pull is required to read a bar code. Scanning
is turned on automatically when an item is placed in reader’s field of view. If the
trigger is pulled, the reader acts as if it in single read mode. Double Read Timeout
on page 74 prevents undesired multiple reads of the same label while in this
mode.
