Visual

The MS9540 has three LED indicators (green, red and yellow) located on the
head of the scanner. The MS9520 has two LED indicators (green* and red*)
located on the head of the scanner. When the scanner is on, the flashing or
stationary activity of the LEDs indicates the status of the current scan and the
scanner.
Green*, Red* & Yellow (MS9540's Only) LEDs are off
The LEDs will not be illuminated if the scanner is not receiving
power from the host or transformer.
The scanner is in stand-by mode, and CodeGate is
enabled. Present a bar code to the scanner and the
green LED will turn on when the laser turns on.
Steady Yellow (MS9540's Only)
The CodeGate button is not active. If a bar code is in the scan
field, the laser will turn on. The bar code will be decoded and
transmitted to the host automatically.
Steady Green
When the laser is active, the green LED is illuminated.
The green LED will remain illuminated until the laser is deactivated
(default mode only).
Steady Green 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 (default mode only).
Steady Green 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.
Alternating Flashing of Green and Red
This indicates the scanner is configuration mode. A razzberry
tone indicates that an invalid bar code has been scanned while in
this mode.
The scanner needs a Flash ROM upgrade if the red and green
LEDs flash alternately and the unit beeps three times during
startup.
* In some custom units the standard green LED has been replaced with a blue LED and
the red LED has been replaced with a white LED.
