12. Using Laser Scanner
A barcode comprises a series of black stripes representing alphanumeric letters. To read
this information properly, follow the instructions below:
WARNING
Laser beam is harmful to eyes.
Never look into the laser beam aperture (head portion) of the unit.
Never direct the aperture to somebody.
When scanning labeled bottles or tubes containing medical material (such as
medicine, reagent, or blood,) the barcode readout is vital. Always verify that the
readout by the scanner agrees with the literal information on the label.
CAUTION
The laser scanner is a precision device. When strong mechanical shock is added
by mistake (dropped, hit etc..,) stop using it and call the vendor of this unit for
checking/repair. Such a scanner may cause frequent read errors or may become
completely inoperative while you are using it.
Do not scan barcodes with labels laid on striped pattern such as paper on which
stripes are printed or grained wood, because the scanner may recognize them as
barcodes.
When using an external scanner connected to this unit, do not damage its cord by
pulling it or winding it round anything. The cord may be broken.
If a barcode label is inside of a plastic bag, take it out before scanning.
Scan a barcode with the label stretched properly. Before scanning, make label
surface clean.
