Safety information
Before installing and using the B4881V50S4H, take note of the following precautions:
•Read all instructions carefully.
•Do not place the unit on an unstable surface, cart, or stand.
•Do not block the slots or openings on the unit which are
provided for ventilation.

does not support this type of plug, contact an electrician to
replace the obsolete outlet.
•Do not place anything on the power cord. Place the power
cord where it will not be stepped on.
•Follow all warnings and cautions in this manual and on the
unit case.
•Do not push objects in the ventilation slots, as they may
touch high voltage components and result in shock and
damage to the components.
•When replacing parts, ensure that you use parts specified
by the manufacturer.
•When service or repairs have been carried out, perform
routine safety checks to verify that the system is operating
correctly.
•Avoid using the system near water, in direct sunlight, or
near a heating device.
•Cover the unit when not in use.
•Disassembly of this unit should not be attempted by
unqualified persons. When the chassis cover is removed
there is a danger of electric shock and risk of damage to
the system.
•Do not attempt to lift or move this product alone. When
moving this product, at least two people should lift it onto a
suitable trolley or cart. When bolting the product into a
