Safet y Sum m ar y
The following are general safety precautions that are not related to any specific
procedure and therefore do not appear elsewhere in this technical manual.
These are recommended precautions that personnel must understand and
apply during most phases of operation and maintenance.
KEEP AWAY FROM LIVE CIRCUIT
Operating personnel must at all times observe all safety regulations.
Do not replace components or make adjustments inside the unit with the high
voltage supply turned ON. Under certain conditions, dangerous potentials may
exist when the power breaker is in the OFF position, also due to charges
retained by capacitors. To avoid casualties, always remove power and
discharge to ground a circuit before touching it.
DO NOT SERVICE OR ADJUST ALONE
Under no circumstances should any person initiate servicing or adjusting the
unit except in the presence of someone capable of helping help.
RESUSCITATION
Personnel working with or near high voltage should be familiar with modern
methods of resuscitation. Such information may be obtained from the Bureau of
Medicine and Surgery.
