FCC Statement
This device complies with FCC Rules part 15. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) This device must
accept any interference that may be received, including interference that may cause
undesired operation. The manufacturer is not responsible for any radio or TV
interference caused by unauthorized modifications to this equipment. Such modification
could void the user’s authority to use 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.
SAR Information Statement
Your CAR ALARM is a radio transmitter and receiver. It is designed and manufactured not to
exceed the emission limits for exposure to radiofrequency (RF) energy set by the Federal
Communications Commission of the U.S. Government. These limits are part of comprehensive
guidelines and establish permitted levels of RF energy for the general population. The guidelines
are based on standards that were developed by independent scientific organizations through
periodic and thorough evaluation of scientific studies. The standards include a substantial safety
margin designed to assure the safety of all persons, regardless of age and health. The exposure
standard for wireless mobile phones employs a unit of measurement known as the Specific
Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg. * Tests for SAR are conducted
with the phone transmitting at its highest certified power level in all tested frequency bands.
Although the SAR is determined at the highest certified power level, the actual SAR level of the
CAR ALARM while operating can be well below the maximum value. This is because the CAR
ALARM is designed to operate at multiple power levels so as to use only the power required to
reach the network. In general, the closer you are to a wireless base station antenna, the lower
the power output. Before a CAR ALARM model is available for sale to the public, it must be tested
and certified to the FCC that it does not exceed the limit established by the government adopted
requirement for safe exposure. The tests are performed in positions and locations (e.g., at the ear
and worn on the body) as required by the FCC for each model. The highest SAR value for this
