SAFETY PRECAUTIONS (Continued)
Do not attempt to override safety interlocks.
Never reach across any system which has not been turned off, the plug pulled, and high voltage capacitors
discharged.
When servicing live electronic equipment, always work with one hand in your pocket or behind your back,
and stand on an insulated pad (e.g., rubber). That way if you get shocked, the current will not pass through
your torso.
Do not carry on conversation or permit yourself to be distracted in any manner while servicing live
equipment.
Never service live equipment unless someone else is in the same room with you.
Never turn off the main power switch in some remote spot and then service equipment without also pulling
plug on line cord.
In the event of shock, artificial respiration should be applied immediately. If possible, by a person trained in
administering such treatment.
WARNING: Always discharge all high-voltage capacitors before attempting any servicing. Do not assume
that the discharge from a capacitor will not produce a lethal shock. The discharge from a high-capacity,
high-voltage capacitor is lethal!
