SETUP
WARNING
CAUTION
PIN Protection Measures
• Do not use the device outdoors.
Electrical
Considerations
Contactless
Considerations
• Avoid using this product during electrical storms.
• Avoid locations near electrical appliances or other devices that cause
excessive voltage fluctuations or emit electrical noise (for example, air
conditioners, electric motors, neon signs, high-frequency or magnetic security
devices, or computer equipment).
• Avoid using the device near water or in moist conditions.
• Disconnect the device from its POS device before cleaning.
Do not use the device near water, including a bathtub, wash bowl, kitchen sink or
laundry tub, in a wet basement, or near a swimming pool to avoid shock or
damage.
Avoid having metallic objects in proximity of the contactless antenna. If you need
to mount the device to vertical or inclined surfaces, use Verifone approved stand.
Using an enclosed metal frame or mount may negatively affect contactless
performance.
PIN Protection
Measures
Use the following techniques to provide effective screening of the PIN-entry
keypad during the PIN entry process. You can use these methods in combination,
although in some cases a single method might suffice.
• Position the device on the check-in stand in such a way as to block visual
observation of the PIN-entry process. Examples include:
• Visual shields designed into the check-in stand. The shields may be solely
for shielding purposes or may be part of the general check-in stand design.
• Position the device so that it is angled in such a way that PIN spying is
difficult.
• Install the PED on an adjustable stand that allows consumers to swivel the
device sideways and/or tilt it forwards/backwards to a position that makes
visual observation of the PIN-entry process difficult.
• Position in-store security cameras so that the PIN-entry keypad is not visible.
• This risk of shoulder-spying during PIN entry can be significantly reduced by
installing the optional approved privacy shield.

Verifone also recommends instructing the cardholder regarding safe PIN-entry.
This can be done with a combination of:
• Signage on the PED
• Prompts on the display, possibly with a click-through screen
• Literature at the point of sale
• A logo for safe PIN-entry process.
• You can secure PIN entry by installing a Privacy Shield (optional).
Verifone recommends the use of an approved stand for all mounting situations.
Position the device conveniently in relation to power, POS, ECR, and LAN
connections. Ensure the M424 device is located in a manner that allows
customers to swipe their magnetic cards or insert their Smart Cards in a smooth
and comfortable motion without encountering obstructions. If the unit needs to be
swiveled during normal operation, Verifone recommends the use of an approved
swivel stand.
Inside the
Shipping Carton
Unpacking the
Shipping Carton
Special care is required while mounting the M424 device in sites that utilize antitheft devices positioned at doorways or surface mounted deactivator pads.
Devices of this type, such as Sensormatic brand devices generate strong
electromagnetic fields, which may interfere with M424 device. Always select
mounting locations at least 0.5 meter from doorway units and at least 2.0 meters
from surface mounted deactivator pads.
Open the shipping carton and carefully inspect its contents for possible tampering
or shipping damage. The device is a secure product. Tampering causes it to
cease to function or to operate in an unsecured manner.
To unpack the shipping carton:
1 Carefully inspect the shipping carton and its contents for possible tampering or
damage.

CHAPTER 4
General Care
Your device is a product of superior design and craftsmanship and should be
treated with care. The following suggestions will help you protect your warranty
coverage.
• Keep the device dry. Precipitation, humidity, and all types of liquids or moisture
can contain minerals that will corrode electronic circuits. If your device does
get wet, switch off the power, and allow the device to dry completely before
replacing it.
• Do not use or store the device in dusty and dirty areas. Its moving parts and
electronic components can be damaged.
• Do not store the device in hot areas. High temperatures can shorten the life of
electronic devices, damage batteries, and warp or melt certain plastics.
• Do not store the device in cold areas. Moisture can form inside the device and
damage electronic circuit boards when the device returns to its normal
temperature.
• Do not drop, knock, or shake the device. Rough handling can break internal
circuit boards and fine mechanics.
• Do not paint the device. Paint can clog the moving parts and prevent proper
operation.
• Keep the device free from any small and loose items (such as paper clips,
staples, or coins) that could accidentally get inside it through an opening, such
as the SAM slots or the primary smart card reader slot.
• Do not attempt to open the device other than as instructed in this guide. This
device has security features that protect it from tampering. For example, the
file content will be deleted if the device’s outer casing is opened.
• Use only the power adapter that came with your device. Adapters for other
electronic devices may look similar, but they may affect your device’s
performance or damage it.
• Do not use this device in any area with a potentially explosive atmosphere.
Follow all signs and instructions. Potentially explosive atmospheres include
areas where you would normally be advised to turn off your vehicle engine.
Sparks in such areas could cause an explosion or fire resulting in bodily injury
or even death.

Cleaning
Cleaning the SCR To clean the SCR:
To clean the device, use a clean cloth slightly dampened with water and a drop or
two of mild soap. For stubborn stains, use alcohol or an alcohol-based cleaner.
Never use thinner, trichloroethylene, or ketone-based solvents – they can
deteriorate plastic or rubber parts.
Do not spray cleaners or other solutions directly onto the device.
The Smart Card Reader (SCR) must be cleaned on a regular basis, as dirt
accumulation can lead to SCR reading problems. SCR can be cleaned using
commercially available card reader cleaning cards or using recommended
Verifone cleaning card (PN 02746-02).
1 Inspect the device’s SCR for presence of foreign objects before cleaning
Customer Smart Card.
34 M424 INSTALLATION GUIDE
a If unit shows no presence of foreign objects, test the SCR function and
record results. Proceed to Step 2.
Send your device to a Verifone authorized repair center if foreign objects are
found in the SCR at any time during SCR inspection, test diagnostics, or cleaning
process. Removal of foreign objects from the SCR by customers may void device
warranty.
2 Clean the SCR with approved or recommended Verifone cleaning card. It is
always advised to use new cleaning cards at all times.
If using a commercially available cleaning card use ONLY an approved SCR
cleaning card made specifically for POS SCR devices or Petroleum SCR.
3 Test the SCR after cleaning.
a If SCR tests out okay as “passing”, then the unit is ready for Customer
Smart Card use.
b If SCR tests out as “failing”, then send the unit for repair. Provide details to
repair center when SCR failed testing, either before cleaning OR after
cleaning OR both before and after cleaning.
MAINTENANCE AND CLEANING
NOTE
CAUTION
Additional Safety Information
Magnetic Stripe
Cleaning
Using the Battery
The Magnetic Stripe Reader (MSR) must be cleaned on a regular basis (daily to
once a week, depending on usage), as dirt accumulation can lead to MSR reading
problems. MSR can be cleaned using commercially available card reader
cleaning cards or using recommended Verifone cleaning card (PN 02746-02).
If using a commercially available cleaning card use ONLY an approved MSR
cleaning card made specifically for POS MSR Card reader devices or Petroleum
MSR card readers.
The Verifone M424 device uses an integrated circuit with a lithium battery having
reverse-charge protection. The internal logic of the battery prevents both
overcharging and undercharging (a fault condition in which the battery level goes
well below the minimum acceptable charge and the battery becomes unusable).
There is a risk of explosion if the battery is replaced by an incorrect type.
