Visual Indicators
There is a red LED and amber LED on
the front of the 7600. When the scanner is on,
the flashing or constant illumination of the LEDs
indicates the status of the current scan and the
scanner.
Figure 25: LEDs
No Red or Amber LED
The LEDs will not be illuminated if the scanner is
not receiving power from the host or transformer.
Steady Amber
When the laser is active, the amber LED is
illuminated. The amber LED will remain
illuminated until the laser is deactivated.
Steady Amber and Single Red Flash
When the scanner successfully reads a bar code,
the red LED will flash and the scanner will 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 Amber and Steady Red
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 red LED will remain on
until the data can be transmitted.
Flashing Amber then Flashing Red
This indicates the scanner is in program mode. A
razzberry tone indicates that an invalid bar code
has been scanned in this mode.
or
If the unit is in sleep mode, each LED will flash
once every 15 seconds.
Steady Red, Amber off
This indicates the scanner may be waiting for
communication from the host.
