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 TV’s 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. Take steps to secure your wireless access
point and network. Your access point's manual should provide additional details about how to implement the
following measures:
Secure your wireless access point's management settings with a unique password to prevent unauthorized
changes to security related settings.
Implement standard encryption (e.g., WPA2 encryption) on your wireless access point to secure your wireless
network signal.
Secure access to your wireless network with a hard-to-guess password.
Confirm your access point's firewall setting is enabled (if so equipped).
Make sure that all your Internet-connected devices are behind your network's firewall.
If your access point or modem has a standby mode button, use it to disconnect your home network from the
Internet when it is not in use.
Use strong passwords for all your Internet accounts (Netflix, Facebook, etc.).
If any unexpected messages appear on your TV screen requesting permission to link a device or enable a remote
session, do NOT accept.
Do not visit suspicious web sites and do not install any suspicious programs. We recommend that users install only
those authorized apps provided by Samsung through Samsung Smart Hub.
Figures and illustrations in this User Manual are provided for reference only and may differ from the actual product
appearance. Product design and specifications may change without notice.

02 TV Installation
TV screen must not be exposed to direct sunlight.
If the TV screen is exposed to direct sunlight, it can develop dark areas. This is a common symptom
of LCD Panel and dark areas will disappear when the screen is taken out of direct sunlight.
Continuous exposure to direct sunlight may cause damage to the TV screen.
The brightness sensor, which is located at the bottom right side of the product, should not be covered
by any object and totally exposed to outside.
The TV will activate "Screen Protection Mode" if it senses too much brightness in the surrounding
area. This will lower the screen's brightness to protect the TV.
For the stable use of the product, it should be installed in a place where there is no risk of freezing due
to snow accumulation or exposure to rain for a long time.
It cannot be installed in a recessed space.
Planning the location

Mounting the TV on a wall
Because access to Media Bay of the TV may be limited due to the design of the wall-mount that you use,
connecting all cables and devices that you need prior to hanging the TV on the wall is recommended. When
connecting additional cables and devices to the TV after hanging on the wall, you may need to separate the
TV from wall-mount.
If you mount this TV on a wall, follow the instructions exactly as set out by the manufacturer. 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).
TVWall mount bracket
C
Samsung Electronics is not responsible for any damage to the product or injury to yourself or others if you choose
to install the wall mount on your own.
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.

Do not install your wall mount kit while your TV is turned on. This may result in personal injury from electric
shock.
Do not use screws that are longer than the standard dimension or do not comply with the VESA standard screw
specifications. 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.
Always have two people mount the TV onto a wall.
WARNING: This apparatus must be securely attached to the wall.
"Tipping, shaking, or rocking the machine may cause injury/death." (CSA60065)
Providing proper ventilation for your TV
When you install your TV, maintain a distance of at least 1.5 inches (38 mm) 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 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.

Water projected by a source greater than 6.3 mm against enclosure from any direction or submersion in water.
Water projected at greater than 30 KPa (4.4 PSI) with a water volume greater than 12.5 litres/minute for more than 3
minutes and extreme weather conditions.
If you have purchased or been provided a Dust Cover in the box with the TV, be sure to apply the Dust Cover to the TV
whenever the TV is not in use for an extended period of time.
The Dust Cover will help prevent dust, dirt, and more from accumulating on the TV. Please refer to the guide provided

transmission of power, Ethernet and control signals including IR and RS232.
General
The appearance may differ depending on the product.
Connecting parts may differ in different products.
Data transmission is not available if HDBase-T (Rx) is connected to HDBase-T (Tx) through a hub.
While installing the product, be sure to use the cables and TX devices certified by the HDBase-T Alliance.
When connecting an external device via HDBase-T, for the maximum resolution, use a certified TX device that
supports 4K 30 Hz.
This port (HDBT port on the TV) does not support ARC (eARC).
