Computer operating guidelines and routine care

Follow the guidelines below to properly set up and care for the computer:
HP recommends a 17 mm clearance from the fins on the rear panel for heat dissipation.
Keep the HP RP9 Retail System away from excessive moisture, direct sunlight, and extremes of heat and
cold.
Never operate the computer with any access panels removed.
Do not stack computers on top of each other or place computers so near each other that they are subject
to each other's re-circulated or preheated air.
If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be
provided on the enclosure, and the same operating guidelines listed above will still apply.
Keep liquids away from the RP9 Retail System.
Never cover the fins on the rear panel of the computer with any type of material.
Install or enable power management functions of the operating system or other software, including
sleep states.
Shut down the computer before you do either of the following:
Wipe the exterior of the computer with a soft, damp cloth as needed. Using cleaning products may
discolor or damage the finish.
Occasionally clean the fins on the rear panel to keep them free of lint, dust, and other foreign
matter that may inhibit heat dissipation from the fins.
NOTE:
For more information on your retail system care and maintenance, refer to "Retail Point of Sales

Touch screen maintenance

Keep your display and touch sensor clean. The touch sensor requires very little maintenance. HP recommends
that you periodically clean the glass touch sensor surface. Be sure to turn off your display before cleaning.
Typically, an isopropyl alcohol and water solution ratio of 50:50 is the best cleaning agent for your touch
sensor. It is important to avoid using any caustic chemicals on the touch sensor. Do not use any vinegar-
based solutions.
Apply the cleaner with a soft, lint-free cloth. Avoid using gritty cloths. Always dampen the cloth and then
clean the sensor. Be sure to spray the cleaning liquid onto the cloth, not the sensor, so that drips do not seep
inside the display or stain the bezel.
