WARNING – FCC RF Exposure Guidelines
While this device is in operation, a separation distance of at least 20cm must be maintained between the radiating antenna and the body of all persons exposed by the transmitter to meet FCC exposure guidelines.
This transmitter is only approved to operate with an antenna not exceeding 1.5 watts total system ERP (effective radiated power) for operations with the antenna located at more than 20 cm from all persons. The warning label must be displayed at the base of the antenna, clearly visible to all persons exposed to the transmitter.
The DART 300 is fitted with a threaded female TNC connector. Any standard 800 MHz cellular antenna of good quality should operate properly.

CAUTION
The combination of cable loss and antenna gain must yield an overall system gain not exceeding 0 dB. The transmitter output of 0.6 Watt is delivered at the connector. This is the FCC regulated limit of a Class III device.
CAUTION
In cases where the antenna output is to be connected to test equipment, DC blocks must be used on the antenna output to protect the test equipment and avoid false booster detection.
