Visual Indicators
There is a red and green LED at the top of the scanner. When the
scanner is on, the flashing or stationary activity of the LEDs indicates
the status of the scan and scanner.
Steady Green
When the laser is on, the green LED is also on. This
occurs when an object is in the scan field.
Steady Green; Red Flash
When the scanner successfully reads a bar code, the red
LED will flash then beep once. If the red LED does not
flash or the scanner does not 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.
No Red or Green LED
There are two reasons why the LEDs will not be illumi­
nated. First, if the scanner is receiving power and the
LEDs are not on, then the scanner has remained dormant
for a specified time and the laser has turned off. To reacti­
vate the unit, touch the touch plate. Secondly, if the
scanner is not receiving power from the host or trans­
former, then the LEDs will not turn on.
Flashing Red
This indicates the scanner has experienced a laser sub­
system failure. Return the unit for repair at an authorized
service center.
