Problem: Article: Take your sound bar out of its original packaging, and make sure you have all the cables, screws, mounts, and manuals in the package. This will allow you to safely plug the cable into your TV and your soundbar. SPDIF cables are also called Toslink or fiber-optic cables. Make sure you have the right cable for your connection type here. There are usually plastic doors covering the optical port to keep the dust out. Make sure the cable snaps in firmly and connected. This should be the same port as the one on the back of your TV. Connect your soundbar to a power outlet with the power cable, and press the Power button to turn it on. Press the Input button on the soundbar remote, and use the arrow keys to select Optical, Toslink, or SPDIF. This will open the VIZIO menu on your TV screen. This will open your soundbar's audio settings. Select the TV Speakers option with your remote, and use the arrow keys on the remote to toggle it off. This will prevent echo effect from multiple sound sources. Select this option on the Audio menu, and use the arrow keys on the remote to switch it to a different setting.
Summary: Unpack your Vizio soundbar. Remove the protective plastic cover on each end of your SPDIF cable. Connect one end of the cable to the "OPTICAL" port on the back of your TV. Connect the other end of the cable to the "OPTICAL" port your soundbar. Make sure your soundbar is powered on. Select the correct input method with your soundbar remote. Press the menu key on your soundbar remote. Select Audio on the menu. Toggle the TV Speakers setting to Off. Change the Digital Audio Out setting to Bitstream or Dolby Digital.

Problem: Article: To build the monkey bars, you'll need at least 13 8 ft (2.4 m) long 2x4 boards. Get a couple of extra 2x4s in the event that you make a mistake while you're cutting. You'll also need to purchase metal monkey bars that have screw holes in each end, measuring tape, miter saw, handsaw/circular saw, 2.5 in (6.4 cm) wood screws, and a power drill. These materials can be found at most hardware stores or online. Whenever you are using electric saws or drills it's important you wear the proper safety gear to prevent injury. Purchase and wear a respirator, goggles, gloves, and earplugs when you are sawing or drilling into the wood. These 4 posts will act as your vertical support beams and will hold up the monkey bars. Measure 88 inches (220 cm) down the length of one of the boards. Draw a straight line across the board and use a handsaw or circular saw to cut the board to the right length. Repeat this process on 4 2x4s.  Line a level up against the line you drew to keep your cuts straight. Use a straightedge to help you keep your saw straight as you cut. Use the same technique that you used on the longer boards to cut these boards to size. These smaller boards will attach to the bottom of the longer planks and will rest against the ground and act as a stand for your monkey bar set. Lay a 2x4 on a flat surface and use a handsaw or circular saw to cut the plank so that it's 25.5 inches (65 cm) long. These braces will be used to support the stand that you're creating. Draw a 45-degree angle on each corner of the 25.5 in (65 cm) braces using a carpenter's triangle. Adjust a miter saw so it cuts on a 45-degree angle and then uses it to cut these planks of wood on each side. These braces will attach to the left and right sides of each of your vertical support posts. The length of the monkey bars will be determined by how many bars you have and how far you want to set them apart. Most sets have 6-10 bars. To calculate how long your set should be, you can count how many bars you have, then multiply that by 10 inches (25 cm). This will make the set long enough to set the bars 10 inches (25 cm) apart. Once you get the measurement for how long you want your set to be, you'll have to cut 2 2x4 boards to the length of your set. This will connect both portions of the monkey bar set together. Purchase bars that have screw holes or a place to mount the bars. Then, measure from screw hole to screw hole, so that you know how far apart your horizontal supports need to be. Most bars that you can purchase online or at a hardware store will be between 1.5–2 feet (0.46–0.61 m) long. Write the measurement on a piece of paper. Search online or at hardware stores for bars made specifically for a monkey bar set. These boards will act like the steps or ladder rungs of your monkey bars. Take the measurement of your bars, and cut the boards so that they are 4 inches (10 cm) longer than your bars.
Summary: Gather the materials for the monkey bars. Wear the proper safety gear when sawing and drilling into wood. Cut 4 2x4 boards so they are 88 inches (220 cm) long. Cut 2 2x4s so they are 57 inches (140 cm) long. Cut 4 25.5 in (65 cm) long cross braces out of 2x4s. Cut a 45-degree angle on each end of the 25.5 in (65 cm) braces. Determine how long you want your monkey bar set to be. Cut boards that run the length of your monkey bar set. Measure the length of your bars. Cut 6 2x4s 4 inches (10 cm) longer than the length of your bars.

Problem: Article: The "vi" part of this command selects the Vim text editor as the program to use. You'll replace "filename" with the name you wish to assign to your new file.  For a file named "tamins", for example, you'd type vi tamins.txt. If your current directory has a file by the same name, this command will instead open that file. This will create your new file and open it in the Vim editor. You should see a blank Terminal window with a tilde (~) on each line, as well as your text file's name at the bottom of the window. Doing so will place your document in "Insert" mode, wherein you can enter text as needed. You should see -- INSERT -- pop up at the bottom of the window when you press the I key. It's typically in the upper-left corner of your computer's keyboard. This key will stop the insert mode. This key will place Vim in "Command" mode. You should see a cursor appear at the bottom of the window. This command will save your document as it currently is. Doing so will quit out of Vim and return you to Terminal's main interface. Your text file is now in your specified directory.  You can check for the text file by typing ls into Terminal and pressing ↵ Enter and then looking for the file's name. You can also type :wq to save and quit in one command. Just as you did to create the file, you'll type vi filename.txt to open the file. This time when you open the file, you should see any saved changes that you made.
Summary:
Type vi filename.txt into Terminal. Press ↵ Enter. Press your computer's i key. Press the Esc key. Press the : (colon) key. Type :w into Terminal and press ↵ Enter. Type :q into Terminal and press ↵ Enter. Reopen the file from the Terminal window.
