When
testing
electronic
equipment,
there
is
always
a
danger
present.
_lJne.xPe"Fq
high
vol-
tages
can
bE
prer"nt
at
unusual
locations
in defective
equipment.
The-
technician
should
beiome
familiar
with
the
device
that
he
is
working
on and
observe
the
following
precautions.
1.
When
making
test
lead connections
to
high
voltage
points, remove
the-poriver.
Illhit
cannot
be
djne,
be
sure
to avoid
contact
wittr
oth-er
equipment
or
_metal
gbjects.

one
hand
in
your
pocket
as
a safety
precaution and
stand
on an
insulated
floor to
reduce
the
possibility of shock.
Z. Discharge
filter
capacitors
before
connecting
test
leads
to
them.
Capacitors
can
store
a
charge
that
could
be dangerous
to
the
technician.
B.
Be
sure
your
equipment
is
in
good
order.
Broken
or
frayed
test
leads can
be extremely
dangerous
and
canexpose
the
technician
to
dangerous
potentials.
4. Remove
the test
leads
immediately
after
the
test
has been
completed
to
reduce
the
possi-
bility
of shock.
b.
Do
not
work
alone
when
working
on
hazardous
circuits.
Always
hlve another
person
close
by
in
case
of
accident.
Rernember,
even
a
minor
shock
can
be the
cause of
a more
serious
u""ia"nt,
such
as
falling
against
the equipment,
or coming
in contact
with
hi$
voltages.
6.
When
using
the
SG165
for
signal
injection,
be sgle
to
discharge
the
capacito-r
in
the
ggc4g
pto-be
to
chassis
beforJeach
connection.
If thiscap_acitor,chargedtoalargeOC

is connected
to
the
base
of a

possible
damage
to
the'hansistor
will
result.
