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
