OPERATING MODES
Scan Mode
The imager 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 options:
Trigger Single (Default) — This mode is associated with
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 fol-
lowing occurs:
• the programmable “maximum scan on time”
1
has
elapsed
• a label has been read
• the trigger is released
Trigger Pulse Multiple — Scanning begins when the trig-
ger is pulled and continues after the trigger is released,
until the trigger is pulled again or until the programmable
“maximum scan on time”
1
has elapsed. Reading a label
does not disable scanning. Double Read Timeout
1
pre-
vents undesired multiple reads while in this mode.
Trigger Hold Multiple — When the trigger is pulled,
scanning starts and the product scans until the trigger is
released or “maximum scan on time”
1
has elapsed. Read-
ing a label does not disable scanning. Double Read Time-
out
1
prevents undesired multiple reads while in this
mode.
Always On — The illuminator is always ON and the reader
is always ready for code reading. Double Read Timeout
1
prevents undesired multiple reads.
Flashing — The reader illuminator flashes on and off
regardless of the trigger status. Code reading takes place
only during the Flash On
2
time. Double Read Timeout
1
prevents undesired multiple reads.
