The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. This symbol indicates that this product incorporates double insulation between hazardous main voltage and user-accessible parts. When servicing, use only identical replacement parts.

To reduce the risk of fire or electric shock, do not expose this product to rain or moisture. This product should not be exposed to dripping or splashing. No objects filled with liquids, such as vases, should be placed on or near the product.

The TV is unstable if it is not properly attached to the base or mounted to the wall. Be sure to follow the base or wall mounting instructions provided in the User’s Guide to ensure your safety.

Cable TV installer notice of proper grounding
This reminder is provided to call your attention to Article 820-40 of the National Electrical Code (Section 54 of the Canadian Electrical Code, Part 1) which provides guidelines for proper grounding and, in particular, specifies that the cable ground should be connected to the grounding system of the building as close to the point of cable entry as practical.

Installation location
Important: This television is a table model and is designed to sit on a firm, flat surface. Don’t place the TV on soft carpeting or similar surfaces because the ventilation slots on the bottom of the unit will be blocked, resulting in reduced lifetime from overheating.

To ensure adequate ventilation for this product, maintain a spacing of 4 inches from the top and side of the TV receiver and 2 inches from the rear of the TV receiver and other surfaces. Also, make sure the stand or base you use is of adequate size and strength to prevent the TV from being accidentally tipped over, pushed off, or pulled off the stand. This could cause personal injury and/or damage to the TV. Refer to the Important Safety Instructions on the following pages.

To completely shut the power off, you must disconnect the power cord from the power outlet. The main plug/appliance coupler is used as a disconnect device. Therefore, you should be sure that the TV is installed in a manner to enables the power cord to be disconnected when necessary.

In situations where the power plug or appliance coupler is used as the disconnect device, the disconnect device shall remain readily accessible and operable.

Choose from hundreds of thousands of streaming movies and TV episodes, plus music, sports, kids, family, international, and much more. You should never run out of things to watch.

A paid subscription or other payments may be required for some channel content. Channel availability is subject to change and varies by country.

Get the most out of your new TV

Follow these steps to get the most out of your new TV.

  • Connect to the Internet
  • It’s easy, and it will unlock a world of entertainment. All you need is a network connection. There are hundreds of free streaming channels, paid subscription services, and convenient ways to rent or buy a favorite movie or program.

  • Find live broadcast and streaming TV programs in the Live TV Channel Guide
  • Use the Live TV Channel Guide to see not only what’s on TV right now, but what will be on in the coming two weeks. And for many over-the-air programs, if you start watching the program after it is already in progress, or you see something you missed in the Live TV Channel Guide, you can use More Ways to Watch to find streaming channels where you can see the program from the beginning, find other episodes, or entire seasons of the program, if applicable.

You can even customize the names of each input and move tiles around so your most used devices and streaming channels are only a click away.

Set up your new TV

To avoid the danger of suffocation, keep plastic packaging away from pets, babies, and children. Do not use packaging bags in cribs, beds, carriages, or playpens.

Open the box and remove the TV and other items. Be careful, the TV is heavy! We strongly recommend that two people unbox the TV. Be sure to check all the foam packaging as the stands from some TVs are stored in the foam for protection.

To use the stand
Your TCL Roku TV comes without the stands attached so you can choose to use the stands or mount your TV to a wall using a wall mount (sold separately). If you want to mount your TV to the wall, don’t attach the stand legs.

  • To prevent damage to the screen, carefully place your TV on a soft, cushioned surface.
  • Put the column of the stands into the TV, and align the stands with the screw holes located on the TV. Secure the stands to the TV with four (4) screws.
    Make sure the installation direction of the stand is the same as illustrated.

Refer to your TV’s Quick Start Guide or other provided documentation for model-specific information about attaching the base or a wall mount and making connections to AC power and your other audio/video devices. The following information applies to all TCL • Roku TV models.

Connecting an antenna, cable, or satellite box
If you are using an antenna, CATV cable without a set-top box, or a cable or satellite box that has only an antenna output, connect a 75-ohm coaxial cable (not provided) from the source to the ANT/CABLE input on the TV.

If you are using an antenna with a 300-ohm twin-lead cable, you need to use a 300-to-75-ohm adapter (not provided) to adapt the twin-lead cable to a connection that is compatible with the TV’s antenna input.

If you receive your TV stations through a set-top box from a cable or satellite TV provider, connect it to the TV using the best connection method available. From most to least desirable.

Select models have an AV Input that looks like a headphone jack. Use the breakout cable (included) to adapt this input to the three RCA-type plugs on your composite cable.

Connecting external equipment with an HDMI®

If possible, connect your devices using HDMI® cables (not provided).  They help to provide the best video quality and also carry audio signals so that only one cable is needed. For better picture quality,  we recommend that you use cables designated as High-Speed HDMI®Cables.

You might need to configure the device to send its signal through its HDMI® connector.

The connector labeled HDMI (ARC) has the additional ability to use the audio return channel to send digital audio to a receiver or soundbar, as explained in Connecting an AV receiver or digital soundbar. Only on select models:

The connector labeled HDMI (eARC) provides the same functionality as the HDMI ARC connector, plus the ability to pass through full-resolution sound formats such as Dolby Atmos and DTS:X from and to devices that support these formats, without additional processing by the TV. Additional details are provided in Choosing an audio format.

Connecting headphones to a Roku Voice Remote

Select TCL • Roku TVs come with the Roku Enhanced Voice Remote or Roku Voice Remote Pro. On these models, you can connect headphones to the jack on the left side of the remote.

Inserting a plug in the remote’s headphone jack disables the sound from the TV’s built-in speakers or attached receiver or soundbar. The volume and mute controls on the right side of the remote adjust the volume level of the connected headphones.

Loud noise can damage your hearing. When using headphones, use the lowest volume setting on your headphones that still lets you hear the sound. You might notice that connecting headphones to your remote shortens the remote’s battery life somewhat.

Roku remote batteries

Review the Battery Caution & Disposal Information on page 167
Open the back of your Roku remote and insert the included batteries, observing the proper orientation as indicated in the battery compartment. Reattach the back cover.

TCL 43S450R 43-Inch Class S4 4K LED Smart TV 4

Use the following information to identify the buttons on your Roku remote.

Remote buttons and features vary somewhat by model. Your remote might not have all buttons or features listed.

  • If your remote has a VOICE just below the purple pad, you have a Roku Voice Remote.
  • If your remote has a headphone jack on its left edge, you have a Roku Enhanced Voice Remote or Roku Voice Remote Pro.
