8-7

Scan a bar code below to select a leading margin duration. A leading margin is the time that precedes the first bar of the scan, (in 
milliseconds). The minimum allowed value is 80 msec and the maximum is 250 msec. This parameter is used to accommodate older 
wand decoders which cannot handle short leading margins.

250 msec is the maximum value that this parameter can attain, however, 200 msec is sufficient.

Note
