SAFETY PRECAUTIONS
There is always a danger present when using electronic equipment.
Unexpected high voltages can be present at unusual locations in defective equipment
and signal distribution systems. Become familiar with the equipment that you are
working with and observe the following safety precautions.
Every precaution has been taken in the design of your Satellite Modulator to
insure that it is as safe as possible. However, safe operation depends on you the
operator.
Always be sure your equipment is in good working order. Ensure that all points
of connection are secure to the chassis, and that protective covers are in place
and secured with fasteners.
