Aiming the Laser Dot:
Sometimes it is difficult to see the laser beam and know you are on the
bar code, especially if you are attempting to read outdoors in direct
sunlight. The laser can be outputted as a brighter dot for a few seconds,
allowing the user to place the dot in the middle of the bar code; then the
laser beam starts sweeping for the read. As shipped, the laser beam
never forms an aiming dot, but you can program a number of seconds
that you wish the aiming dot to appear before the sweeping beam by
scanning the following:
From the Keypad, go to RF Terminal Setup. Choose “Other”. Press
Enter repeatedly until you get to the parameter labeled “AIMING
DOT”. The default is 00. Enter the time in 1/10s of a second you wish
the dot to appear before the laser beam spreads, (i.e. enter 30 for 3
seconds).
"Difficult Code 39 Reading
":
This setting facilitates reading of difficult Code 39 bar codes such as
the Vehicle Identification Number (VIN number) on automobiles,
especially reading through a windshield. VIN numbers are long, often
weathered, often dirty, and challenging to read.
To enable the more aggressive Code 39 algorithms necessary to read
windshield VINs with a LZ400:
Scan Start Setup
Scan 2 of 5 Code
Scan D for windshield reading
Scan End Setup
To return to the default Code 39 decode algorithms, scan B instead
of D.
Don’ forget the common sense things you can do to facilitate reading
the VIN:
1. Be sure the window on the laser scanner is clean.
2. Be sure the windshield itself is wiped clean before
reading
