The reader can be set to operate in one of several scan-
ning modes. See the PRG for more information and set-
tings for any of the following options:
Trigger Single (Default)

typical handheld reader operation. When the trigger is
pulled, illumination is turned on and the scanner attempts
to read a label.
Scanning is activated until one of the following occurs:
•
the programmable “maximum scan on time”

has
elapsed
• a label has been read
•
the trigger is released
Trigger Pulse Multiple -
Scanning begins when the trigger
is pulled and continues after the trigger is released, until
the trigger is pulled again or until the programmable

does not disable scanning. Double Read Timeout

vents undesired multiple reads while in this mode.

ning starts and the product scans until the trigger is

its field-of-view. The Aiming Pattern is always on to show
the optimum reading area. If a predefined amount of
movement is detected, the red illumination switches on.
Scanning continues until a label is read or "maximum scan
on time"
