TARTING
THE
L
ASER
Simply
press
the
Power
button
on
the
display
panel
to
start
the
laser.
As
the
system
prepares
for
operation
the
screen
will
display
the
MPH
logo
and
go
through
several
internal
checks.
Figure

‐
System
Initialization
Screens
The
display’s
pixels
can
be
checked
as
a
checkerboard
pattern
displays
and
then
reverses
allowing
you
to
identify
any
pixels
that
are
stuck
on
or
not
illuminating.
The
laser
will
then
proceed
to
check
the
Non
‐
volatile
memory
(EEPROM),
the
internal
laser
timing
circuit
and
the
internal
crystal.
If
any
of
these
tests
fail,
the
testing
will
immediately
stop
and
the
test
result
will
show
FAIL
on
the
screen.
If
the
tests
do
not
fail,
the
screen
will
display
PASS
for
each
test.
The
next
page
will
check
to
make
sure
the
flash
memory,
main
microcontroller
and
display
microcontroller
checksums
are
all
correct.
The
final
internal
check
will
list
the
serial
number
of
the
unit
itself.
As
all
of
these
internal
tests
are
happening
on
the
display,
the
heads
up
display
(HUD)
will
also
be
going
through
a
segment
check
as
well.
Once
the
unit
has
powered
up
barring
any
failures,
the
display
will
go
directly
to
the
HOME
screen
and
the
unit
will
be
ready
to
use.

IRING
THE
L
ASER
Simply
hold,
aim
and
fire.
1.
Hold
the
laser
close
and
aim
the
reticle
(crosshairs
or
other
reticle)
onto
a
specific
target.
2.
Once
the
target
is
identified
in
the
HUD,
simply
hold
the
reticle
on
the
target
without
moving
the
laser
and
pull
the
trigger
until
the
target
has
been
acquired
at
which
time
the
laser
will
sound
an
auditory
tone
to
signify
the
speed
and/or
range
was
calculated.
