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 data 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  
scanner.  
• Change the distance between the bar code and  
the scanner.

4.2 READ OPERATION MALFUNCTIONING  
? Trigger key has no scan function.  
• If your bar code data collector has a display,  
check in your display if the scan menu is  
selected. When an other menu is selected switch  
to the scan menu.  
When the barcode data collector has a problem  
with reading the label:  
? General tips.  
• Change the angle of the bar code data collector  
relative to the bar code.  
? Laser temperature has become too high.  
• The laser is switched off automatically, when the  
laser temperature becomes above 50°C. Wait  
until the temperature has dropped.  
• Change the distance between the bar code and  
the bar code data collector.  
? The label consists of small bars with small  
spaces (high-resolution label).  
Barcode data collector does not work, when  
pressing the trigger key.  
• Decrease the distance between the bar code and  
the bar code data collector.  
? The battery is empty.  
• Charge the barcode data collector in the cradle.  
? The bar code is larger than the laser beam.  
Try moving the bar code data collector a bit  
further away from the bar code.  
Bar code data collector can be used only for a  
short time after recharging.  
? The reading window is dirty.  
• Clean the reading window of the bar code data  
collector.  
? The main battery is not properly charged.  
• Check if the charging contacts of the bar code  
data collector and the cradle are clean. If  
needed, clean the charging contacts.  
• Check the cradle for power by checking the power  
supply and/or the mains socket.  
? The type of the bar code label is not enabled.  
• If applicable, enable the bar code symbology in  
the application program.  
• Check if the bar code data collector is properly  
placed on the cradle.  
? The error occurs consistently with a certain batch  
of labels.  
• Verify the barcode. If you use a barcode printer it  
is advised to use also a barcode verifier.  
When the product needs to be repaired:  
The label with serial number should be present. If  
returning the product, please use the original  
packaging to minimise the chance of damage.
