Reading distance for the Advanced Long Range Laser
Barcode symbologies are always measured in mils. This usually refers to the narrowest bar
width. One mil equals 0.001”, therefore a 0.01” wide narrow bar would be a 10 mil
barcode.
Conversion: 1 mil = 0.0254 mm
1 inch = 25.4 mm
These charts show typical performance at 68°F on high quality bar code symbols.
The M5900 Scanner LED
The M5900 has a multi-color LED to indicate when the unit has scanned a bar code successfully.
When the scan button is pushed, the LED above the on/off button will turn a solid red. Once the
scanner has successfully read the bar code, this LED will turn a bright green.
This visual indication of a good read is useful in very noisy environments where the audio beeper
can not be heard. If the red LED turns off, it means the bar code can not be read.
