(2) Barcode scanner auto power off (APO) 
This function automatically turns off the barcode scanner when the barcode scanner function is 
not used for a certain period of time. Even after turning off the bar code scanner, the power is 
turned on automatically when you use the bar code scanner. The APO time can be set in the 
range of 0 to 65535 seconds. You can also disable barcode scanner APO. 
Power consumption is reduced while the bar code scanner is off. However, it takes several tens 
to several hundred milliseconds to turn on the bar code scanner, so setting the APO time shorter 
may cause poor response. The default imager APO time is 60 seconds.
