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: 1.) Reorient or relocate the receiving antenna. 2.) Increase the separation between the equipment and receiver. 3.) Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. 4.) Consult the dealer or an experienced radio/TV technician for help. Note: The device (or CENTRON) transmission duty cycle is limited by its design not to exceed 0.12%. This device complies with Part 15 of 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

Limit for power density for general population/uncontrolled exposure is f/1500 mW/cm 2 for 300 – 1500 MHz frequency range: P = 916/1500 = 0.61 mW/cm 2 The power density P (mW/cm 2 ) = P T / 4 π ππ π r 2 P T is the transmitted power, which is equal to the peak transmitter output power 11.0 dBm plus maximum antenna gain 4 dBi, the maximum equivalent isotropically radiated power EIRP is P T = 11.0 dBm + 4 dBi = 15.0 dBm = 31.6 mW. The power density at 20 cm (minimum safe distance, required for mobile devices), calculated as follows: 31.6 mW / 4π (20 cm) 2 = 0.006 mW/cm 2 << 0.61 mW/cm 2 General public cannot be exposed to dangerous RF level.
