Visual Indicators

There is a red LED and a green LED located on the scanner. When the scanner is on, the flashing or stationary activity of the LEDs alert you to the status of the scan and scanner.

No Red or Green LED

There are two reasons why the LEDs will not be illuminated. First, if the scanner is receiving power and the LEDs are not on, then the scanner has remained dormant for a specified period of time and the laser has turned off. To reactivate the unit, wave an object in front of the IR sensor. Secondly, if the scanner is not receiving power from the host or transformer, then the LEDs will not turn on.

Steady Green

When the laser is on, the green LED is also on. This occurs when an object is in the scan field. The green LED will remain on until the IR time-out has elapsed or until the scanner is turned off.

Steady Green; Red Flash

When the scanner successfully reads a bar code, the red LED will flash followed by one beep. If you do not see the red LED flash or the scanner beep once, then the bar code has not been successfully read.

Steady Red and Green

After a successful scan, the scanner transmits the data to the host device. When the host is not ready to accept the information, the scanner’s red LED will remain on until the data can be transmitted.

Alternating Red and Green

This indicates the scanner is in program mode.

Steady Red

This indicates the scanner is in ScanSet mode.

Flashing Red

This indicates the scanner has experienced a laser subsystem failure. Return the unit for repair at an authorized service center.
