This product
is
intended to operate in an oscilloscope connected to a power source
that will not apply more than 250 V rms between the supply conductors or between
either supply conductor and ground. A protective ground connection, by way of the
grounding conductor in the oscilloscope power cord,
is
essential for safe operation.
This product is grounded through the grounding conductor of the oscilloscope
power cord. To avoid electric shock, plug the oscilloscope power cord into a prop-
erly wired receptacle before connecting to the product input or output terminals.
A protective-ground connection, by way of the grounding conductor in the oscillo-
scope power cord,
is
essential for safe operation.
Upon loss of the protective-ground connection, all accessible conductive parts (in-
cluding knobs and controls that may appear to. be insulating), can render an electric
shock.
To avoid explosion, do not operate this product in an atmosphere of explosive gas-
ses.
Do not perform internal service or adjustment of this product unless another per-
son capable of rendering first aid and resuscitation is present.
Dangerous voltages exist at several points in this product. To avoid personal injury,
do not touch exposed connections and components while power is on.
Disconnect power before removing protective panels, or replacing components.
