White and blue LEDs are located near the bottom corner of the vertical output window on the StratosS. When the scanner is
ON, the flashing or constant, illumination of the LEDs indicates the status of the StratosS and the current scan. There is an
additional amber LED next to the scale zero symbol on all StratosS models that include a scale (see figure below).
Figure 29. LEDs
No White or Blue LED
The LEDs will not be illuminated if the scanner is not receiving power from the host or transformer. They are also not
illuminated when all lasers are turned off for any reason.
Steady Blue
When all lasers are active, the blue LED is illuminated. The blue LED will remain illuminated until all lasers are deactivated.
Steady Blue and Single White Flash
When the scanner successfully reads a bar code, the white LED will flash and the scanner will beep once. If the white LED
does not flash or the scanner does not beep once, then the bar code has not been successfully read.
Steady White and Blue
After a successful scan, the scanner transmits the data to the host device. Some communication modes require that the
host inform the scanner when data is ready to be received. If the host is not ready to accept the information, the scanner’s
white LED will remain on until the data can be transmitted.
Flashing Blue then Flashing White
This indicates the scanner is in configuration mode. A razzberry tone indicates that an invalid bar code has been scanned in
this mode.
If the unit is in sleep mode, each LED will flash once every 15 seconds.
Steady White, Blue Off
This indicates the scanner may be waiting for communication from the host.
Flashing Blue
This indicates there is an error active on the diagnostic indicator display (see Error Codes on page 35). The scanner may
continue to operate depending on the type of error.
Steady Amber LED
The amber LED is illuminated when the scale is at zero.
