FEDERAL COMMUNICATIONS COMMISSION INTERFERENCE STATEMENT
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment
is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required
to correct the interference at his own expense.
This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter.
The available scientific evidence does not show that any health problems are associated with using low power wireless
devices. There is no proof, however, that these low power wireless devices are absolutely safe. Low power Wireless devices
emit low levels of radio frequency energy (RF) in the microwave range while being used. Whereas high levels of RF can
produce health effects (by heating tissue), exposure of low-level RF that does not produce heating effects causes no known
adverse health effects. Many studies of low-level RF exposures have not found any biological effects. Some studies have
suggested that some biological effects might occur, but such findings have not been confirmed by additional research.
WX-CT420 has been tested and found to comply with FCC/IC radiation exposure limits set forth for an uncontrolled
environment and meets the FCC radio frequency (RF) Exposure Guidelines in Supplement C to OET65 and RSS-102 of the
IC radio frequency (RF) Exposure rules.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to
operate the equipment.
This device complies with Part 15 of FCC Rules and Industry Canada licence-exempt RSS standard(s). Operation is subject
to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference,
including interference that may cause undesired operation of this device.
WARNING:
p
To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.
p
The apparatus should not be exposed to dripping or splashing and that no objects filled with liquids, such as vases, should
be placed on the apparatus.
p
All work related to the installation of this product should be made by qualified service personnel or system installers.
p
The risk of hearing impairment due to exposure to excessive sound levels may be reduced by listening at lower volumes
and for shorter durations.
p
Operating near
1.9
GHz electrical appliances may cause interference. Move away from the electrical appliances.
p
This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter.
p
MEDICAL:
Consult the manufacturer of any personal medical devices, such as pacemakers, to determine if they are adequately
shielded from external RF (radio frequency) energy. (The unit operates in the frequency range of
1.92
GHz to
1.93
GHz,
and the power output level is
115mW max.
)
Do not use the unit in health care facilities if any regulations posted in the area instruct you not to do so. Hospitals or health
care facilities may be using equipment that could be sensitive to external RF (radio frequency) energy.
p
Batteries (battery pack or batteries installed) shall not be exposed to excessive heat such as sunshine, fire or the like.
