Honeywell International Inc. QC900A Manuale Utente

An audio signal (default ON) provides a quick indication if a scan passes or fails 
the current test.  You can change the pitch/volume of these beeps (see 

 on page B-1).  After a scan, one short, high pitch beep 

indicates that the symbol passes an appropriate group of tests, while one long, 
low pitch beep indicates that it fails.

The QC890 Verifier supports the Reflectometer mode.  In the Reflectometer 
mode, the unit operates as a free-running reflectometer.  See

 

for additional information.

A DC power barrel on the back of the unit connects to a power supply for external 
power and battery charging.

The DB9 port on the unit connects to the pen wand, mouse wand, or customized 
imager.  Refer to
