Location of the Controls
The
laser
controls
for
the
SL/SLx
are
located
on
the
front
of
the
console
and
positioned
at
a
safe
distance
from
the
laser
aperture.
Manual Restart
The
SL/SLx
immediately
disables
all
laser
circuits
upon
interruption
of
the
Remote
Interlock
circuit
or
loss
of
line
power.
In
this
event,
the
SL/SLx
must
be
manually
reset
by
cycling
the
keyswitch
off
and
on.
Internal Power Monitor
The
power
emitted
from
the
delivery
device
is
indicated
on
the
display.
Two
internal
power
monitors
independently
measure
the
laser
power
before
energy
is
emitted
through
the
delivery
device.
If
the
measurements
from
the
two
monitors
differ
significantly,
the
console
will
display
a
warning
message
instructing
the
user
to
call
IRIDEX
Technical
Support.
Footswitch
Depressing
the
footswitch,
while
in
Treat,
delivers
the
treatment
beam.
If
the
footswitch
is
damaged
or
improperly
connected,
Treat
cannot
be
selected
and
the
Connect
Footswitch
message
will
be
displayed.
The
footswitch
can
be
safely
immersed
and
cleaned
(in
compliance
with
IPX8
per
IEC
60529),
and
is
shrouded
for
maximum
safety
(in
compliance
with
ANSI
Standard
Z136.3,
4.3.1).
Long Term Reliability
A
crystal
oscillator
controls
the
timing
of
the
Pulse
Duration.
Initial
uncertainty
in
the
measurement
is
less
than
1
ms.
The
level
of
uncertainty
is
not
expected
to
increase
or
decrease
over
the
life
of
the
product.
Power
is
automatically
controlled
by
optical
sampling
circuits.
Initial
uncertainty
in
the
measurement
is
less
than
5%
of
the
requested
power,
including
laser
power
meter
uncertainties.
This
uncertainty
is
not
expected
to
increase
or
decrease
by
more
than
1%
of
the
requested
power
over
the
life
of
the
product.
Laser
delivery
is
affected
by
many
parameters,
just
one
of
which
is
the
accurate
control
of
optical
energy.
Other
factors
include
cleanliness
and
condition
of
delivery
devices
as
well
as
alignment
accuracy.
