NOTE: For more information on your retail system care and maintenance, go to http://www.hp.com/
support. Then type ‘Retail Point of Sales Systems - Routine Care and Maintenance’ and click Search all
support.
Touch screen maintenance
Keep your touch screen clean. The touch screen requires very little maintenance. HP recommends that you
periodically clean the glass surface. Be sure to turn o your display before cleaning. Typically, an isopropyl
alcohol and water solution ratio of 50:50 is the best cleaning agent for your touch screen. It is important to
avoid using any caustic chemicals on the touch screen. 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.
MSR maintenance
To clean the MSR (magnetic stripe reader), swipe a standard cleaning card through the MSR a couple of times.
You can order a standard cleaning card online. You can also put a thin oil-free cloth around a credit card.
Operating guidelines and routine care 13
Cleaning the barcode scanner
Exterior surfaces and scan windows exposed to spills, smudges, or debris require periodic cleaning to ensure
best performance during scanning. Use a soft, dry cloth to clean the product. If the product is very soiled,
clean it with a soft cloth moistened with a diluted non-aggressive cleaning solution or diluted ethyl alcohol.
IMPORTANT: Do not use abrasive or aggressive cleansing agents or abrasive pads to clean scan windows or
plastics. Do not spray or pour liquids directly onto the unit.
Cleaning the printer
Because of the way the printer sits while in use, paper and other debris from the knife can build up. HP
recommends that you keep the printer in working order by periodically cleaning the debris from the printer.
To clean the printer, open the cover, remove the paper roll, and then use a can of compressed air to blow out
the debris from the bottom plate where it accumulates.
Cleaning I/O ports
The computer has a series of ports. Dust and debris can collect in these ports, which can reduce connectivity
and performance. Use a battery-powered vacuum to remove any debris that has accumulated in and around
these ports.

Electrostatic discharge information
A sudden discharge of static electricity from your nger or other conductor can destroy static-sensitive
devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device
exposed to electrostatic discharge (ESD) may not appear to be aected at all and can work perfectly
throughout a normal cycle. The device may function normally for a while, but it has been degraded in the
internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge
contains enough power to alter device parameters or melt silicon junctions.
IMPORTANT: To prevent damage to the device when you are removing or installing internal components,
observe these precautions:
Keep components in their electrostatic-safe containers until you are ready to install them.
Before touching an electronic component, discharge static electricity by using the guidelines described in this
section.
Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
If you remove a component, place it in an electrostatic-safe container.
Generating static electricity
Note the following:
● Dierent activities generate dierent amounts of static electricity.
● Static electricity increases as humidity decreases.

Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of
sensitivity. The following packaging and grounding precautions are necessary to prevent static electricity
damage to electronic components.
Electrostatic discharge information 15
● To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.
● Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.
● Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
● Place items on a grounded surface before removing them from their container.
● Always be properly grounded when touching a sensitive component or assembly.
● Avoid contact with pins, leads, or circuitry.
● Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive
foam.
Personal grounding methods and equipment
Use the following equipment to prevent static electricity damage to electronic components:
● Wrist straps are exible straps with a maximum of one-megohm ± 10% resistance in the ground cords.
To provide proper ground, a strap must be worn snug against bare skin. The ground cord must be
connected and t snugly into the banana plug connector on the grounding mat or workstation.
● Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible with
most types of shoes or boots. On conductive oors or dissipative oor mats, use them on both feet with
a maximum of one-megohm ± 10% resistance between the operator and ground.

How is data input into this
memory?
RTC battery backed-up CMOS
is programmed using
Computer Setup (BIOS), or by
changing the Microsoft®
Windows date & time.
NIC EEPROM is programmed
using a utility from the NIC
vendor that can be run from
DOS.
DIMM SPD is programmed by
the memory vendor.
Bluetooth ash is
programmed at the factory.
Tools for writing data to this
memory are not publicly
available but can be obtained
from the silicon vendor.
How is this memory
write-protected?
This memory is not writeprotected.
A utility must be used to
write data to this memory
and is available from the
NIC vendor. Writing data
to this ROM in an
inappropriate manner will
render the NIC nonfunctional.
Data cannot be written to
this memory when the
module is installed in a
computer. The specic
write-protection method
varies by memory vendor.
A utility must be used for
writing data to this
memory and is made
available through newer
versions of the driver
whenever the ash
requires an upgrade.
