Multiple Symbols
When this programming selection is turned On, it allows you to
read multiple symbols when the trigger is activated. If you press
and hold the trigger, aiming the Imager at a series of symbols, it
reads unique symbols once, beeping (if turned on) for each read.
The imager attempts to find and decode new symbols as long as
the trigger is activated. When this programming selection is turned
Off, the Imager will only read the symbol closest to the aiming
beam.
No Read
With No Read turned On, the Imager notifies you if a code cannot
be read. If using a Quick*View Scan Data Window, an “NR”
appears when a code cannot be read. If No Read is turned Off, the
“NR” will not appear.
Multiple Symbols Note: This feature does not
work when the Imager is in
Low Power mode.
