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
