If it is not correctly mounted, the TV may slide or fall and cause serious injury to a child or adult and serious damage to the TV. Refer to the installation manual included with the Samsung wall mount kit. You can mount the TV on the wall using a wall mount kit (sold separately).

Before attaching the wall mount to surfaces other than plaster board, contact your nearest dealer for additional information. If you install the TV on a ceiling or slanted wall, it may fall and result in severe personal injury. When installing a wall mount kit, we recommend you fasten all four VESA screws. If you want to install a wall mount kit that attaches to the wall using two top screws only, be sure to use a Samsung wall mount kit that supports this type of installation. (You may not be able to purchase this type of wall mount kit, depending on the geographical region.) Standard dimensions for wall mount kits are shown in the table on the next page. If you are installing a third-party wall mount, note that the length of the screws you can use to attach the TV to the wall mount is shown in column C in the table on the next page.

This may damage the product or cause the product to fall, leading to personal injury. Samsung is not liable for these kinds of accidents. Samsung is not liable for product damage or personal injury when a non-VESA or non-specified wall mount is used or when the consumer fails to follow the product installation instructions. Do not mount the TV at more than a 15 degree tilt. Always have two people mount the TV onto a wall. For 82 inch or larger models, have four people mount the TV onto a wall. Providing proper ventilation for your TV When you install your TV, maintain a distance of at least 4 inches (10 cm) between the TV and other objects (walls, cabinet sides, etc.) to ensure proper ventilation. Failing to maintain proper ventilation may result in a fire or a problem with the product caused by an increase in its internal temperature. When you install your TV with a stand or a wall mount, we strongly recommend you use parts provided by Samsung Electronics only. Using parts provided by another manufacturer may cause difficulties with the product or result in injury caused by the product falling.

State of California Proposition 65 Warning WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov English - 4 Internet security Samsung takes a number of steps to protect its Internet-compatible Smart TVs against unauthorized incursions and hacking. For example, certain sensitive communications between the TV and the Internet servers are encrypted. In addition, the TVs operating system has adopted controls to prevent the installation of unauthorized applications. Although we take steps to protect your Smart TV and personal information, no Internet-connected device or transmission is completely secure. We therefore encourage you to take additional steps to safeguard your TV, secure your Internet connection, and minimize the risk of unauthorized access. These steps are listed below:

When Samsung releases software updates to improve the security of your TV, you should promptly install these updates. To automatically receive these updates, turn on Auto Update in the TV's menu (

Settings > Support

> Software Update > Auto Update). When an update is available, a popup message appears on the TV screen. Accept the software download and update by selecting Yes when prompted.

If it is not correctly mounted, the TV may slide or fall and cause serious injury to a child or adult and serious damage to the TV. Refer to the installation manual included with the Samsung wall mount kit. You can mount the TV on the wall using a wall mount kit (sold separately).

To order the wall mount kit, contact Samsung service center at 1-800-SAMSUNG (1-800-726-7864). You can install your wall mount on a solid wall perpendicular to the floor. Before attaching the wall mount to surfaces other than plaster board, contact your nearest dealer for additional information. If you install the TV on a ceiling or slanted wall, it may fall and result in severe personal injury. When installing a wall mount kit, we recommend you fasten all four VESA screws. If you want to install a wall mount kit that attaches to the wall using two top screws only, be sure to use a Samsung wall mount kit that supports this type of installation. (You may not be able to purchase this type of wall mount kit, depending on the geographical region.) Standard dimensions for wall mount kits are shown in the table on the next page. If you are installing a third-party wall mount, note that the length of the screws you can use to attach the TV to the wall mount is shown in column C in the table on the next page.

Screws that are too long may cause damage to the inside of the TV set. For wall mounts that do not comply with the VESA standard screw specifications, the length of the screws may differ depending on the wall mount specifications. Do not fasten the screws too firmly. This may damage the product or cause the product to fall, leading to personal injury. Samsung is not liable for these kinds of accidents. Samsung is not liable for product damage or personal injury when a non-VESA or non-specified wall mount is used or when the consumer fails to follow the product installation instructions. Do not mount the TV at more than a 15 degree tilt. Always have two people mount the TV onto a wall. For 82 inch or larger models, have four people mount the TV onto a wall. Providing proper ventilation for your TV When you install your TV, maintain a distance of at least 4 inches (10 cm) between the TV and other objects (walls, cabinet sides, etc.) to ensure proper ventilation. Failing to maintain proper ventilation may result in a fire or a problem with the product caused by an increase in its internal temperature. When you install your TV with a stand or a wall mount, we strongly recommend you use parts provided by Samsung Electronics only. Using parts provided by another manufacturer may cause difficulties with the product or result in injury caused by the product falling. English - 8 Safety Precaution: Securing the TV to the wall to prevent falling Caution: Pulling, pushing, or climbing on the TV may cause the TV to fall.
