Using the Reader
Aiming System
The PowerScan™ M8500 reader uses an intelligent aiming system similar to those on
cameras. By partially pulling the trigger, the aiming system indicates a field of view to be
positioned over the code:
Figure 6. Aiming System
When you pull the trigger completely a red beam illuminates the code. If the aiming system
is centered and the entire symbology is within the aiming system, you will get a good read.
The field of view changes size as you move the reader closer or farther away from the code.

. Relative Size and Location of Aiming System Pattern
The field of view indicated by the aiming system will be smaller when the PowerScan™
PM8500 is closer to the code and larger when it is farther from the code. Symbologies with
smaller bars or elements (mil size) should be read closer to the unit. Symbologies with larger
bars or elements (mil size) should be read farther from the unit. (See "Technical Features"
starting on page 173 for further details).
