User manual
(1) this device must not cause harmful interference
(2) this device must accept any interference received, including interference that may cause undesired operation.
Any modifications not expressly approved by this company could void the user's authority to operate the equipment.
NOTE : This device has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio
communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio
or television reception, which can be determined by simply turning the equipment off and on, the user is encouraged to try to correct the
interference with one or more of the following ways:

Reposition the receiving antenna.

Increase separation between the equipment and receiver.

Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

Consult the dealer or an experienced radio/TV technician for assistance.
Labels and symbols are displayed on the device as shown in the following images:
1.5.8 (ESD) Electrostatic discharge sensitivity symbol
The (ESD) symbol required by the international standard EN 60601-1-2 is used in the vicinity of any connector which has not undergone
electrostatic discharge testing.
WARNING
Pins of connectors identified with the ESD warning symbol should not be touched and the connections should not be made to these
connectors unless ESD precautionary procedures are used.
Precautionary procedures are the following:

Environmental procedures as: air conditioning, humidification, conductive floor coverings, non-synthetic clothing

User procedures as: discharging one’s body to a large metal object, using wrist strap connected to earth.
It is recommended that all staff involved receive an explanation of the ESD warning symbol and training in ESD precautionary procedures.
the electrostatic discharge is defined as an electric charge at rest. It is the sudden flow of electricity between two objects caused by contact, an
electrical short, or dielectric breakdown. ESD can be caused by a buildup of static electricity by tribocharging, or by electrostatic induction. At lower
relative humidity, as the environment is drier, charge generation will increase significantly. Common plastics generally will create the greatest static
charges.
Typical electrostatic voltage values:
Walking across a carpet
1.500
– 35.000 volts
Walking over untreated vinyl floor 250
– 12.000 volts
Vinyl envelope used for work instructions 600
– 7.000 volts
Worker at a bench 700
– 6.000 volts
If two items are at different electrostatic charge levels, as they approach one another, a spark or Electrostatic Discharge (ESD) can occur. This
rapid, spontaneous transfer of electrostatic charge can generate heat and melt circuitry in electronic components.
A latent defect can occur when an ESD sensitive item is exposed to an ESD event and is partially degraded. It may continue to perform its intended
function, so may not be detected by normal inspection. Intermittent or permanent failures may occur at a later time.
Static dissipative material will allow the transfer of charge to ground or to other conductive objects. The transfer of charge from a static dissipative
material will generally take longer than from a conductive material of equivalent size. Some well known insulators are common plastics, and glass.
An insulator will hold the charge and cannot be grounded and conduct. the charge away.
Both conductors and insulators may become charged with static electricity and discharge. Grounding is a very effective ESD control tool, however,
only conductors (conductive or dissipative) can be grounded.
The fundamental ESD control principles are:

Ground all conductors including people

Remove insulators, substitute with ESD protective versions

neutralize with ionizers

ESDS outside the EPA (ESD protected area) to be in packaging having ESD shielding property
