Reading Parameters
Move the reader toward the target and center the aiming pat-
tern and illumination system to capture and decode the 
image. See 
"Using the Gryphon™ I GBT/GM4500" on page 16

The aiming system will briefly switch off after the acquisition 
time, and if no code is decoded will switch on again before the 
next acquisition. The illuminator will remain on until the sym-
bol is decoded.
As you read code symbols, adjust the distance at which you 
are holding the reader.
