Step 4 Select Adaptive Or Fixed Mode - Microscan MS-Q Imager User Manual

Step 4 — Select Adaptive or Fixed Mode
This feature is available for MS-Q Quadrus models only.
When you read symbols in the MS-Q default setup, the imager is in Adaptive Mode. In
this mode, when the imager is activated by the handle trigger, it attempts to decode in both
the near field and far field resolutions, checks for both light background or dark background
images, and cycles through various gain values until a decode is achieved. It remains with
those settings unless no decode occurs within ten attempts, in which case it resumes the
adaptive routine.
If your application involves relatively similar symbols at consistent ranges, you might
speed up decode rates by switching the imager from Adaptive Mode to Fixed Mode.
When you switch to Fixed, the optimum settings acquired in Adaptive will be locked in.
This means that the imager will not have to search through the various settings to arrive at
the optimum. However, the settings will be fixed to the distance, symbol background, etc.
that were in effect when the last decode occurred in the Adaptive Mode.
Toggling Between Adaptive and Fixed
To toggle between the Adaptive and Fixed Modes:
1. Find a position that gives you the best
decodes. (See Determine Optimum
Position on page 3-3.)
2. Press both the left and right top
buttons at the same time and hold
until you see both LED indicators (on
top) flash RED
that the imager is now in Fixed Mode.
3. To return to Adaptive Mode, press
both buttons again until the indicators
flash GREEN
