*
The
output
power
selected
should
be
as
low
as
possible
and
activation
times
should
be
as
short
as
possible
for
the
intended
purpose.
*
When
uncertain
of
the
proper
control
set-
ting
for the
power
level
in
a
given
procedure,
start
with
a
low
setting
and
increase
as
required
and/or
consult
the
manufacturer.
*
Observe
all
caution
and
warning
symbols
printed
on
the
cover
of
the
unit.
*
The operating
room
staff
should
never
con-
tact
electrosurgical
electrodes
(either
active
or
dispersive)
while
the
RF
output
of
the
unit
is
energized.
*
The
tips
of
recently
activated
accessories
may
be
hot
enough
to
burn
the
patient
or
ignite
surgical
drapes
or
other
flammable
material.
*
Do
not
ignore
unexpected
activation
tones.
Check
to
determine
the
cause
of
the
tone,
oth-
erwise
injury
can
occur.
*
Temporarily
unused
active
electrodes
should
be
stored
in
an
electrically
insulated
container.
The
unused
active
electrode
should
never
be
placed
on
the
patient.
This
is
especially
impor-
tant
for
laparoscopic
procedures.
1.1.4
CAUTIONS
For
Testing
or
Servicing
*
Service
should
not
be
attempted
without
reference
to
sections
3
and
4
of
this
manual.
*
This
electrosurgical
unit
should
be
tested
by
qualified
maintenance
personnel
on
a
periodic
basis
to
ensure
proper
and
safe
operation.
It
is
recommended
that
examination
of
the
unit
be
performed
at
least
yearly.
*
Refer
all
servicing
to
qualified
personnel.
Your
CONMED
representative
will
be
happy
to
assist
you
in
getting
your
equipment
ser-
viced.
*
High
voltages
are
developed
within
the
unit
that
are
accessible
when
the
top
cover
is
removed.
These
voltages
are
potentially
dan-
gerous
and
should
be
treated
with
extreme
caution.
a
*
The
high
voltage
DC
power
supply
in
the
Excalibur
Plus
PC™
is
equipped
with
a
bleed-
er
resistor
to
dissipate
the
charge
on
the
filter
capacitor.
However,
it
takes
several
seconds
after
power
is
removed
to
bleed
that
charge
down
to
a
safe
level;
it is
recommended
that
at
least
thirty
(30)
seconds
be
allowed
to
elapse
before
touching
or
attempting
to
perform
any
maintenance
involving
the
power
supply
or
power
amplifier.
+
Never
remove
or
install
any
parts
with
power
on.
*
Avoid
contact
with
the
output
leads
when
the
unit
is
activated.
Periodically
inspect
the
test
leads
used
for
the
output
connections
for
obvious
defects.
*
Although
this
unit
will
withstand
momen-
tary
short
circuits
on
the
output,
prolonged
short
circuits
may
damage
the
unit.
Short
cir-
cuiting
the
output
should
be
avoided
since
it
is
neither
necessary
nor
desirable.
*
Since
the
clinical
use
of
electrosurgical
units
is
intermittent
in
nature
with duty
cycles
on
the
order
of
10%,
this
unit
is
not
designed
to
operate
for
extended
periods
of
continuous
output.
When
testing,
it
is
recommended
that
duty
cycles
be
limited
to
50%
with
maximum
activation
times
of
30
seconds.
*
Life
of
the
equipment
will
be
extended
by
minimizing
operating
temperature
and
extreme
thermal
cycles.
*
The
heat
dissipation
capability
of
the
heat
sink
is
impaired
by
activating
the
Excalibur
Plus
PC™
in
other
than
its
normal
operating
position.
¢
Ensure
that
the
two
top
cover
screws
are
tightened,
and
always
perform
a
power-up
check
to
confirm
a
normal
power-up
sequence
before
returning
the
unit
to
service.
