Thermal

The vent hole of the POC-W181 rear cover functions as a cooling air flow inlet and
outlet. These air inlets and outlets transfer heat from inside the computer to the
cooler air outside. Do not block these holes/vents by any soft material.
When using your POC-W181 system, it is normal for the rear metal heatsink to get
warm. The rear metal heatsink of the POC-W181 functions as a cooling surface that
transfers heat from inside the computer to the cooler air outside. Do not block this
heatsink by any soft material.
Warning! Your AC cord came equipped with a three-wire grounding plug (a plug
that has a third grounding pin). This plug will fit only a grounded AC out-
let. If you are unable to insert the plug into an outlet because the outlet is
not grounded, contact a licensed electrician to replace the outlet with a
properly grounded outlet. Do not defeat the purpose of the grounding
plug.
Warning! Never push objects of any kind into this product through the openings in
the case. Doing so may be dangerous and result in fire or a dangerous
electric shock.
Never place anything on the system case before turning off computer.
Never turn on your computer unless all of its internal and external parts
are in place.
Operating the computer when it is open or missing parts can be danger-
ous and can damage your computer.
