CAUTION FOR SAFETY
Please read this page before repair
ing
the monitor.
This page explains t
he
following items for keep
ing
the safety of
the
set and prevent
ing
accidents
during repair.
S
ymbol
s used:
Warning
This symbol means
"possib
i
l
ity of death
or heavy damage"
Caution
This symbol means
"possib
i
l
ity of
damage or break
age
"
This symbol means
"CAUTION"
This symbol means
"POSSIB
I
L
ITY
of
ELECTRIC SHOCK"
This symbol means
"MUST"
This symbol means
"DO NOT"
F
ollow instructions.
Special attention parts are
indicate
d
on cabinet, chassis and
parts by label
.
Please follow t
he
note
s in
[Safety In-
structions]
in the
User’s Manual.
Prevent electric shock.
T
ake care during working be
cause
the
monitor has high voltage part
s
and power supply part
s
.
Possib
i
l
ity of electric shock
if
these
parts are touched
.
D
isconnect
the mains
plug during
overhaul, reassembl
y
or
parts
change.
Death
or
injury
by electric
shock may
occur if live parts are touched
.
Use recommended components.
Components and parts with special
characteristics for safety or reliability
are indicated in parts lists and circuit
diagrams by the
mark.
Electric shock or fire may occur if non-
recommended components or parts
are used.
Keep the same style of wiring.
The
Monitor uses
insulating
tubes
or tapes for safety and
some comp
-
onents are kept at a
distance from
PCB surfaces for
safety.
Internal leads
are
kept from hot
-
or high
voltage part
s
by clamper
s
or styling
.
R
eturn
wiring
to original condition
after
repair to
prevent electric shock or fire.
Perform
safety check after finish
ing
.
Every part (removed screws, compo-
nent
s
and wiring) should be returned
to its original
condition.
Check around
the
repair position for
damage and measure
insulation
impedance by
using a
meg-ohm me-
ter.
Confirm
that
the value of impedance
is more than 4M ohm.
E
lectric shock or fire
may occur
if
th
e
value is less than 4M ohm.
The code and combination circuit of the
HDCP
is not a repairable item
.
Never remove the shield case
that
is
assembled to the code and combination
circuit of
the
HDCP.
