DS551LT7 User Manual 12
When hanging from a ceiling
Ensure that the ceiling is strong enough to support the LCD and it accessories. Also consider the effects of
earthquake, unexpected vibration, and other external forces when evaluating the ceiling strength.
The LCD should be secured to the building’s structural frame, such as a beam, and not to materials such as light
steel frame or interior decoration.
Do not use wood screws or dry wall anchors for installation.
Maintenance
Inspect the fasteners regularly for signs of loosening or deformation. Please perform appropriate corrective
measures when a problem is identified. Neglecting the problem may worsen the situation.
Increase the inspection frequency on areas where previous maintenance had occurred to ensure the problems
do not occur again.
