HP RP7 Retail System Model 7800 - Manual (Page 18)

Reading Parameters
The scanner default is Automatic Object Sense Reading mode. Simply present the bar code label in
front of the scanner and center the aiming pattern and illumination system to capture and decode the
image. See
Using the Scanner on page 8 for more information.
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. While movement and the object are being sensed,
illumination will remain on until the symbol is decoded.
As you read code symbols, adjust the distance at which you are holding the object to optimize
reading performance.
Aiming System
A number of options for customizing control of the Aiming System are available. See the HP Retail
Integrated Barcode Scanner Programming Reference Guide (PRG) for more information and
programming bar codes.
Good Read Green Spot Duration
Successful reading can be signaled by a good read green spot indication.
Use the bar codes that follow to specify the duration of the good read pointer beam after a good read.
