Safety Cautions
When a malfunction occurs, disconnect the power plug
from the power outlet and take measures to prevent
other people coming near the plasma display.
In the cases such as
· The plasma display is loose and vibrates to an extreme degree,
· Mounting screws or parts are loose or missing,
failure to take appropriate actions can result in injury.
Perform the following actions immediately whenever a
malfunction occurs.
1.Turn off the plasma display power switch.
2.Disconnect the power plug from the power outlet.
3.Surround the area with rope, etc., to prevent other people coming near.
4.Contact your local dealer.
Ask your dealer to install, move or adjust the angle
of the ceiling mount unit.
Incorrect installation or adjustment can cause the plasma display
to fall.
The ceiling where the ceiling mount unit is to
be installed must fully support the weight of
the plasma display and the ceiling mount unit
for an extended period of time.
Take measures to fully withstand earthquake,
other vibration and external forces.
Incorrect installation can cause the plasma display to fall
and cause injury.
Total load of the (plasma display + ceiling mount unit) = 51kg
· Always use bolts, washers and nuts to firmly install on a
rigid construction member such as ceiling beam, etc.
· Do not mount directly on a ceiling of insufficient strength or
use wood screws or anchor screws that do not have
sufficient strength to reliably resist pulling out.
· When installing the ceiling mount unit on ceiling
construction members, use commercially available 10mm
nominal diameter screws that are appropriate for the
construction members.
