POTENTIAL FOR ELECTROMAGNETIC
INTERFERENCE
To avoid inaccurate results caused by electromagnetic interference
between electrical and electronic equipment, do not use the device
near a cell phone or microwave oven. For most wireless communication
devices, it is recommended to maintain a distance of 10.8 feet (3.3m) in
order to avoid electromagnetic interference.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
NOTE: The manufacturer is not responsible for any radio or TV
interference caused by unauthorized modifications to this equipment.
Such modifications
could void the user authority to operate the equipment.
NOTE: This equipment 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 turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the 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 help.

• Recommended separation distances between portable and mobile RF communication equipment
and the device.
The device is intended for use in an electromagnetic environment where radiated RF disturbances are under control.
User can help prevent electromagnetic interference by keeping the device at a minimum distance from portable and
mobile RF communications equipment (transmitters). Below table details the maximum output power of transmitter:
RF energy is used only to maintain device's operation.
Therefore, its RF emissions are so low that it's not likely
to cause any interference in nearby electronic equipment.
The device is suitable for use in all establishments,
including domestic establishments, and those directly
connected to the public low-voltage power supply network
that supplies buildings used for domestic purposes.
Electromagnetic environment–
guidance
Floors should be wood, concrete
or ceramic tile. If floors are
covered with synthetic material,
the relative humidity should be at
least 30 %.
Power frequency magnetic fields
should be at levels characteristic of
a typical location in a typical com-
mercial or hospital environment.
Mains power quality should be
that of a typical commercial or
hospital environment.
Mains power quality should be
that of a typical commercial or
hospital environment.
Mains power quality should be that
of a typical commercial or hospital
environment. If the user of the de-
vice requires continued operation
during power mains interruptions,
it is recommended that the device
be powered from an uninterruptible
power supply or a battery.
