Apply power to the circuit under test before connecting low impedance test
equipment (such as pulse generators, etc.). When testing is complete,
disconnect the test equipment before power is removed from the circuit under
test.

Be sure to ground all electrically powered test equipment. Connect a ground
lead (-) from the test equipment to the board or module before connecting the
test probe (+). When testing is complete, remove the test probe first, and then
remove the ground lead.

Place all boards and RadioBlades on a conductive surface (such as a sheet
of aluminum foil) when removed from the system. The conductive surface
must be connected to ground through 100kΩ.

Never use non-conductive material for packaging boards or RadioBlades for
shipment or storage. All units should be wrapped with anti-static (conductive)
material. Replacement units shipped from the factory are packaged in a
conductive material.

Warning!
This product relies on the building’s installation for short-circuit (over current)
protection. Ensure that a fuse or circuit breaker no larger than 120VAC, 15A U.S.
(240VAC, 10A international) is used on the phase conductors (all current-carrying
conductors).
