CAUTION:
This
product
contains
a
high-pressure
mercury
vapor

break
without
warning,
denoted
by
a

sound,
and
mercury
vapor
may
be

Inhaling
mercury
or
mercury
compounds

Protection
against

breakages
To
reduce
the
risk
of
health
problems,
we
recommend
the
following
if
the

breaks:
v
Leave
the
room
immediately
and
carefully
ventilate
the
room
for
at
least
180
minutes.
v
Use
care
when
cleaning
up
any
material
ejected
from
the
projector.
Use
cut
proof
gloves
to
avoid
contact
of
material
with
skin.
Wash
your
hands
after
cleaning
up
the
area.
v
Discard
any
nearby
food
and
drink,
and
thoroughly
clean
the
surface
around
the
projector.
v
Disposal
of
waste
may
be
regulated
under
applicable
environmental
laws
due
to
the
presence
of
mercury.
Dispose
of
these
materials
as
required
by
local
ordinances
and
regulations.
v
If
you
experience
any
discomfort
or
irritation,
seek
medical
attention
immediately.
v
Contact
Service
and
Support
for

Service
Do
not
attempt
to
service
a
product
yourself
unless
instructed
to
do
so
by
the
Customer
Support
Center.
Use
only
a
service
provider
who
is
approved
to
repair
your
particular
product.
Note:
Some
parts
can
be
upgraded
or
replaced
by
the
customer.
These
parts
are
referred
to
as
Customer
Replaceable
Units,
or
CRUs.
Lenovo
expressly
identifies
CRUs
as
such,
and
provides
documentation
with
instructions
when
it
is
appropriate
for
customers
to
replace
those
parts.
You
must
closely
follow
all
instructions
when
performing
such
replacements.
Always
make
sure
that
the
power
is
turned
off
and
that
the
product
is
unplugged
from
any
power
source
before
you
attempt
the
replacement.
If
you
have
any
questions
or
concerns,
contact
the
Customer
Support
Center.
Power
cords
and
power
adapters
Use
only
the
power
cords
and
power
adapters
supplied
by
the
product
manufacturer.
Never
wrap
a
power
cord
around
the
power
adapter
or
other
object.
Doing
so
can
stress
the
cord
in
ways
that
can
cause
the
cord
to
fray,
crack
or
crimp.
This
can
present
a
safety
hazard.
Always
route
power
cords
so
that
they
will
not
be
walked
on,
tripped
over,
or
pinched
by
objects.
Protect
the
cord
and
power
adapters
from
liquids.
For
instance,
do
not
leave
your
cord
or
power
adapter
near
sinks,
tubs,
toilets,
or
on
floors
that
are
cleaned
with
liquid
cleansers.
Liquids
can
cause
a
short
circuit,
particularly
if
the
cord
or
power
adapter
has
been
stressed
by
misuse.
Liquids
can
also
cause
gradual
corrosion
of
the
power
cord
terminals
and/or
the
connector
terminals
on
the
adapter
which
can
eventually
result
in
overheating.
