IMPORTANT NOTICE
Because of the nature of wireless communication, transmission and reception of data can never
be guaranteed. Data may be delayed, corrupted (i.e., have errors), or be totally lost. Significant
delays or losses of data are rare when wireless devices such as the Guardian are used in a
normal manner with a well-constructed network. Guardian should not be used in situations
where failure to transmit or receive data could result in damage of any kind to the user or any
other party, including but not limited to personal injury, death, or loss of property. CalAmp
accepts no responsibility for damages of any kind resulting from delays or errors in data
transmitted or received using Guardian, or for the failure of Guardian to transmit or receive
such data.

RF EXPOSURE COMPLIANCE REQUIREMENTS
The Guardian radio is intended for use in the Industrial Monitoring and Control
and SCADA markets. The Guardian unit must be professionally installed and must ensure a
minimum separation distance listed in the table below between the radiating structure and any
person. An antenna mounted on a pole or tower is the typical installation and in rare instances,
a 1/2-wave whip antenna is used.

Note: It is the responsibility of the user to guarantee compliance with the FCC MPE
regulations when operating this device in a way other than described above.
The Guardian radio uses a low power radio frequency transmitter. The concentrated energy
from an antenna may pose a health hazard. People should not be in front of the antenna when
the transmitter is operating.
The installer of this equipment must ensure the antenna is located or pointed such that it does
not emit an RF field in excess of Health Canada limits for the general population. Recommended
safety guidelines for the human exposure to radio frequency electromagnetic energy are
contained in the Canadian Safety Code 6 (available from Health Canada) and the Federal
Communications Commission (FCC) Bulletin 65.
