Cautions

Note: Opening this product can result in voiding the warranty. The internal
workings of this product can only be accessed by Intermec service personnel.
Integrated circuits on the printed circuit board (PCB) in the computer
are very sensitive to damage by electrostatic discharge (ESD). Prevent
ESD by always wearing skin contact ground straps firmly attached to the
equipment metal base assembly when working inside of the computer.
Never open the package without safeguarding the entire work area with
ESD protection. Failure to comply may result in damage to PCB
components.
Because finger oils can dissolve the reflective coating of the plastic
mirrors, always wear finger cots or non-powdered latex gloves when
handling optical parts.
This icon appears at the beginning of any procedure in this manual that
could cause you to touch components (such as printed circuit boards)
that are susceptible to damage from electrostatic discharge (ESD). When
you see this icon, you must follow standard ESD guidelines to avoid
damaging the equipment you are servicing.
