MANDATORY SAFETY INSTRUCTIONSTO INSTALLERS AND USERS
Use Only manufacturer or dealer supplied antennas.
Antenna minimum safe distance: 35 cm.
Antennas used for this transmitter must not exceed an antenna gain of 3 dBi.
The FCC (Federal Communications Commission) has adopted a safety
standard for human exposure to RF energy which is below the OSHA
(Occupational Safety and Health Act) limits.
Antenna mounting: The antenna supplied by the manufacturer or radio dealer
must not be mounted at a location such that during radio transmission, any
person can come closer than the above indicated minimum safe distance to the
antenna (i.e. 35cm).
To comply with current FCC RF Exposure limitations, the antenna must be
installed at or exceeding the minimum safe distance indicated above, and in
accordance with the requirements to the antenna manufacturer or supplier.
Vehicle installation: The antenna can be mounted at the center of a vehicle metal
roof or trunk lid if the minimum safe distance is observed.
Antenna substitution: Don’t substitute any antenna for the one supplied or
recommended by the manufacturer or radio dealer. You may be exposing
person(s) to excessive radio frequency radiation. You may contact your radio dealer
or the manufacturer for further instructions. Warning
Maintain a separation distance from the antenna to person(s) at least 108cm.

Caution:
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 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: 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.

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’s authority to operate the equipment.
