Q: It's important to do this before you plug in any speakers or audio equipment. Look for at least one of the following on the back or side of the TV.   RCA - A red circular port and a white circular port. RCA is known as "analog" audio.  Optical - A square (sometimes hexagonal) port. Optical audio is known as "digital" audio.  Headphone - The standard 3.5 millimeter jack used for most headphones. You'll usually see an image of a pair of headphones above this port.  HDMI - Typically used for combined audio and video. Some stereo receivers connect via HDMI. Your individual speakers will almost always have RCA inputs, with the left speaker using a white input and the right speaker using a red input. If you're attaching a soundbar-type stereo system, your speaker set will likely have an optical input. You don't need to use an audio receiver with a soundbar. Unless you're using a soundbar or computer speakers with your TV, you need to use a stereo receiver (or amp) to connect to your TV. Your receiver will have at least one of the following inputs:  RCA Optical HDMI For example, if your receiver only has an optical input and your TV only has RCA outputs, you'll need an RCA to Optical adapter. This also applies for TVs that only have headphone outputs, as you can buy a headphone-to-RCA adapter. You can usually find RCA, optical, HDMI, and headphone cables and their accessories online, but most tech department stores carry them as well.
A: Turn off and unplug your TV. Find your TV's audio output slots. Check your speakers' input type. Check your receiver's input type. Determine whether or not you need an adapter. Buy any cables that you don't have.

Q: Although emergencies require rapid action, the most important factor in effectively handling the situation is to keep calm. If you find yourself becoming confused or anxious, stop what you're doing. Take a deep breath. Remember that to be calm in a stressful situation you must deliberately adjust your behavior. Reassure yourself that you can handle the situation.  The reason you feel panicked in an emergency is the result of your body's automatic overproduction of the stress hormone cortisol. The cortisol goes to the brain and slows down the pre-frontal cortex, which is the region responsible for planning complex action. By overriding your body's reaction, you can continue to access your critical thinking faculties. You won't be responding from emotion, but from rational thought. Look around and assess the situation to see what needs to be done before acting. In the USA, call 911 for emergency assistance. Use whatever number is applicable to call emergency services outside the U.S. This phone number will reach an emergency dispatcher who will need to know your location and the nature of the emergency.  Answer all of the questions the dispatcher asks. The job of the dispatcher is to provide quick, appropriate emergency response. She can only do this by asking these questions. If you're calling on a traditional telephone or a GPS-equipped cell phone, emergency services may be able to track your location even if you're unable to speak. Even if you can't talk, call emergency services and someone will be able to find you to provide help. It may be a good idea to go over how you would communicate during an emergency, especially if you have a reason to expect an emergency might arise. What signs indicate that there is an emergency? Is this a medical emergency, or is there a threat to the property/building that may result in human injury? It's important to stop and take inventory of the situation calmly before reacting to the emergency.  An injury due to motor vehicle accident, or smoke inhalation or burns from a fire are examples of medical emergency situations. A medical emergency consists of sudden physical symptoms, such as intense bleeding, head trauma, loss of consciousness, chest pain, choking, sudden dizziness or weakness. Intense desire to hurt yourself or someone else constitute a mental health emergency. Other mental health changes may also be considered an emergency, such as sudden changes in behavior or experiencing confusion, can be an emergency if they occur without cause. Behavioral emergencies are best met by remaining calm, watching from a short distance, and encouraging the person in crisis to stay calm as well. This way you can react appropriately if the situation becomes volatile. Chemical spills, fires, breaking water pipes, electrical outages, natural disasters such as floods or fires are all examples of potential workplace emergencies. If you have advance warning of the possibility of an emergency, such the warning of flood, heavy snow, tornado, etc., you may be better prepared. However, the nature of an emergency is to be unexpected.  When assessing emergency situations, be aware that the situation may be volatile. It may change rapidly. If you have advance warning of an emergency, prepare ahead of time for the best results. Assaults or threats of violence at a workplace or home are emergencies that call for rapid response. In most cases, there is no predictable pattern or method to these emergencies. These situations tend to be unpredictable, and they change quickly.  If you find yourself in an emergency of this nature, keep yourself safe. Run to a safe location, or find shelter in place. Do not fight, except as a last resort. Being attentive to warning signs in your workplace, including any act of physical violence (pushing, shoving, etc.) should be immediately. Your office should have a procedure for workplace violence, including a phone number you can call to report the situation. If you don't know your office's procedures, ask your supervisor or a trusted coworker. Open, honest communication between employees and supervisors is part of maintaining a safe, healthy workplace. For example, if one person appears injured, are you or anyone else in danger of also being injured? For example, if one person is caught in a machine, is the machine turned off? If there has been a chemical spill, is the spill spreading towards anyone else? Is the person caught in structure that's collapsing?  If the threat isn't contained, this will affect your response. Be aware that any emergency situation may change abruptly, so that ongoing assessment is required. If you, or others, are at risk of being harmed, leave the situation immediately. If you have an evacuation plan, follow it. Go to an area where you will be safe.  In a situation where you cannot leave, find the safest possible location within your given area. For example, hiding beneath a solid surface, such as a desk or table, may help if there is a chance of being hit by falling debris. If you're near a car accident, make sure you're not in the line of oncoming traffic. Get off the road. Be aware that in an emergency, elements are likely to change quickly. In your assessment, notice if volatile or combustible elements are present. For example, in an auto accident, gasoline may catch fire abruptly. If you can safely assist someone else in leaving a dangerous situation, do so. If returning to the emergency situation is risky, a trained rescue person may be better equipped to retrieve anyone in harm's way.  Offering verbal reassurance to an injured person if he is conscious will help another person, even if you can't move them. Let that person know who you are and what is happening to them. Ask them questions to keep them conscious. If the emergency is stable, stay with the victim.
A:
Remain calm. Seek additional help. Determine the nature of the emergency. Know that sudden changes can be emergencies. Be alert for human-caused emergencies. Assess the immediate threat. Remove yourself from danger. Help others leave a hazardous area.
