Spotter Beam
The Extended Range Scanner (Catalog No. 2755-HUG-9) has a two
position trigger. The first detent turns on a spotter beam. Center the
spotter beam over the center of the symbol or press the trigger all the
way to start the scan beam.
Correct Incorrect
Automatic Shutoff
The scanner will automatically stop scanning after a bar code symbol has
been read. If no symbol is decoded, the scanner will automatically stop
after approximately 4 seconds. You must release and press the trigger
again to resume scanning.
Audible Response
When scanning a bar code symbol, listen for a single short beep from the
decoder. This beep indicates that the bar code has been successfully
scanned. Some decoders cannot provide an audible response.
Note: You will not hear an audible response if you are using the scanner
with Allen-Bradley unattended decoders (Catalog No. 2755-DS1x,
-DD1x).
