CAUTION Observe screw torque specifications, especially with screws
that secure directly into plastic standoffs.
CAUTION To avoid mismatching screws and holes, keep the screws for
each piece with that piece as you remove modules and circuit assemblies.
It is possible to mistakenly install machine screws in locations intended for
plastite screws. Plastite screws have a Torx-pan head.
Required tools and equipment
• Phillips #1 screwdriver
• T-10 Torx screwdriver
• 3mm hex key
