Visual Indicators
The imager has blue and white LED
indicators surrounding the button on the
top of the imager. When the imager is on,
the intensity of the LED and the flashing or
stationary activity of the LEDs, indicates
the status of the current scan and the
diagnostic imager.
No LEDs are Illuminated
The LEDs will not be illuminated if the imager is not receiving power from the
host or transformer.
Steady Low Intensity Blue
The imager is in stand-by mode. Present a bar code to the imager and the blue
LED will switch to a high intensity blue when the IR detects the object.
Steady High Intensity Blue
The high intensity blue LED is illuminated when the imager is active and
attempting to decode a barcode.
Single White Flash
When the imager successfully reads a bar code the imager will beep once and
the white LED will flash once indicating data has been transmitted successfully.
The blue LED will return to the low intensity state if no other objects are
presented in the active scan area.
If the imager does not beep once and the white light does not flash, then the bar
code has not been successfully read.
Steady White
When the imager successfully reads a bar code it will beep once and the white
LED will turn on indicating data is being transmitted.
Note: After a successful scan, the imager transmits the data to the host device.
Some communication modes require that the host inform the imager when
data is ready to be received. If the host is not ready to accept the
information, the imager’s white LED will remain on until the data can
be transmitted.
Alternating Flashing of Blue and White
This indicates the imager is in configuration mode. A short razzberry tone
indicates that an invalid bar code has been scanned while in this mode.
