DO NOT expose the repeater to rain, snow or any liquids.
DO NOT reverse the polarities of the power supply when
connecting the repeater.
DO NOT apply an RF signal of more than 20 dBm (100 mW)
to the antenna connector. This could damage the repeater's
front end.

repeater.
2. DO NOT open the repeater until the repeater is
disconnected from its power source.
