RF Exposure Compliance Requirements

The Guardian serial 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 antenna or radiating

structure and any person. An antenna mounted on a pole or tower is the typical installation

and in rare instances, a ½-wave whip antenna is used.

Minimum Safety Distance

Antenna Gain

5 dBi 10 dBi 15 dBi

VHF at maximum Power 123 cm 218.8 cm 389 cm

UHF at Maximum Power

105.7 cm

900 MHz at Maximum Power 63.8 cm 115 cm 201.7 cm

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 serial 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), the Federal Communications Commission (FCC) Bulletin 65.

Any changes or modifications not expressly approved by the party responsible for compliance (in the

country where used) could void the user’s authority to operate the equipment.
