4 READING BAR CODES
TAKE CARE OF THE 'HANDLING
INSTRUCTIONS' AND 'GET STARTED'
PRECAUTIONS.
Instructions
• The scanning sequence is defined by the user’s
application. A typical sequence is described
below:
• Press the [PW] key to turn power on.
Check the display for the message: READ BAR
CODE
Point the terminal to the bar code and press the
trigger key.
• Fit the bar code in the laser beam from margin to
margin and pass the scanner to the bar code, as
shown in the scan position illustration.
• The bar code will be read and the reading results
will be indicated.
A "Good Read" means that the scanner has
effectively recognised and decoded the bar code.
In most cases, the application program will provide
an indicator signal or a buzzer signal to indicate a
good read to the user.
The bar code collector is a Class I laser product
conforming to the strictest laser safety standards.
However, we recommend that you avoid looking
directly into the laser beam emitter, or pointing the
laser beam directly into someone's eyes.
Barcode reading problems
When the barcode can not be read, try the
following:
• Check that the width of the bar code label does
not exceed the width of the light beam.
• Change the angle between the bar code and the
product.
• Change the distance between the bar code and
the product.
