Your amp should have a label near the speaker output jack that indicates the output power (measured in Watts) and the minimum impedance (measured in Ohms). Your sub-woofers should also be labeled with an impedance value (in Ohms) and a value indicating the maximum power input that they can handle (in Watts). You should have at least four different values written down. Amp Output Power Amp Minimum Impedance Speaker Power Rating Speaker Impedance To do this you should add together the speaker impedance number for all of your speakers. You want the impedance to be at least equal to the minimum impedance value of your amp on each channel, but not to exceed 16 Ohms unless your amp is specifically rated for impedance values above 16 Ohms. The formula for finding total impedance for speakers wired in series is Z1 + Z2 + Z3 . = Ztotal. Where Z is the impedance of a given speaker. For example, if you have three speakers with impedance values of 4 Ohms, 6 Ohms, and 8 Ohms your total impedance wired in series would be 18 Ohms (4+6+8=18). The formula for finding total impedance of speakers wired in parallel is a little trickier. It is (Z1 x Z2 x Z3) / (Z1 + Z2 + Z3) =Ztotal. So say you have two speakers with impedances of 6 Ohms and 8 Ohms. This time it would look like this: 1) Multiply the values. 6 x 8 = 48 Ohms 2) Add the values. 6 + 8 = 14 Ohms 3) Divide the top by the bottom to find your total impedance. 48/14 = 3.43 Ohms (rounded) You can also use an impedance calculator such as this one http://www.speakerimpedance.co.uk/. This will be based upon the total impedance and the power output of your amplifier. You can use variations of Ohm's Law to do the calculations yourself or you can refer to the online calculator above.

If you think that you or someone you know may have avoidant personality disorder, the first step in getting a diagnosis is to see a doctor for an exam. The doctor will want to rule out any physical conditions that may be causing the symptoms. This appointment will consist of a physical exam, as well as a detailed examination of the patient's personal and family history. If no physical conditions are identified, the doctor will most likely refer the patient to a mental health professional, such as a psychiatrist or psychologist. Mental health professionals are specially trained to diagnose personality disorders, including avoidant personality disorder. This appointment will consist of a detailed interview. The psychiatrist or psychologist will want to know all about the symptoms the patient is experiencing, when they started, and how they have progressed over time. There is not medical test that can be performed to diagnose avoidant personality disorder. A diagnosis is made based on the observations of the patient's behavior and reported symptoms. Once a patient is diagnosed, he or she will be encouraged to enter psychotherapy to help overcome the symptoms of avoidant personality disorder. Some people with avoidant personality disorder also suffer from other mental health issues, such as anxiety and depression. A thorough psychiatric evaluation should reveal whether any other conditions are complicating the symptoms of avoidant personality disorder. For patients who also suffer from anxiety or depression, medications may be helpful in reducing symptoms. Medications are typically not helpful for patients whose only diagnosis is avoidant personality disorder, however.

An echocardiogram can help diagnose several conditions. Your doctor may perform an echocardiogram if they think you may have: Heart murmurs Heart valve problems Atrial fibrillation An infection of the valves Fluid around the heart Blood clots Thickening of the walls of the heart Congenital heart disease High blood pressure in your lungs (pulmonary hypertension) There are several types of echocardiograms and the doctor will choose which one to do based on what information they want to have. A transthoracic echocardiogram. This is a noninvasive procedure that does not hurt. The doctor puts gel on your chest and then moves a handheld machine called a transducer against your chest. The transducer projects ultrasound through your body. A computer reads the sound waves and produces pictures. This test can detect valve problems and enable the doctor to examine the thickness of the walls of the heart. A transesophageal echocardiogram. During this test, the doctor will put a tube with a transducer on it down your throat. This lets the doctor get pictures from a different angle than the transthoracic echocardiogram. You will get medication to help you relax and numb your throat. A stress echocardiogram. During this test, the ultrasound images will be produced while you exercise on a treadmill, ride a stationary bike, or receive medication to make your heart beat faster. This test can find problems that happen when your heart is under stress including conditions where your heart does not receive enough blood. There are several different techniques the doctor may use. They enable the doctor to make different measurements. M-Mode. This technique generates a outlines showing the heart's size, the chambers, and the thickness of the walls of the heart. A doppler echocardiogram. During this test, the machine measures the sound waves that are reflected off of the cells in your blood and uses this information to determine how your blood is flowing through your heart. The doctor can measure how fast the blood is flowing through your heart and in what direction it is traveling. This is useful for determining whether your heart is pumping enough blood and if you have any valve problems. Color doppler. During this method the computer highlights areas where the blood is flowing in a particular direction. This is helpful for detecting blood that is not flowing the correct direction. Two-dimensional echocardiography. This method produces a two-dimensional image of the heart as it beats. This is used to investigate the structures and valves of the heart. Three-dimensional echocardiography. This produces a much more detailed image which has depth instead of just length and width. It is often used to plan treatments.

Hopefully, you've been using iTunes on your apple product. If so, use a computer that has previously recognized your iPhone by connecting with your lightning to USB cord or similar charger. Your phone may be recognized and start rebooting immediately. Usually, more further action is needed. It is advantageous to have the most recent version of iTunes, if possible. This should take less than ten seconds, and will force your iPhone to respond. When the iPhone is unplugged and these buttons are held together it will give it a force reboot. When plugged into iTunes, your phone will be put into Device Firmware Update (DFU) mode. To select your phone, watch for the small phone icon to appear. It will appear underneath the volume controls, on the left-most side of the screen. By clicking the icon, it will take you to the phone's summary panel, allowing you to restore or look at personal statistics. In the summary panel, you will see the option to restore. After clicking this button, a prompt will come up, asking if you wish to restore. A factory restore will reset all settings back to the originals. This means all of your phone personalization and photos, music, text messages, will be lost. Only restore if you have a previous backup or you have no other option. After an automatic restart that may take several minutes, your phone will populate the "Slide to Set up" screen. By following all prompts, you can choose the language of your phone, the time zone, and similar settings. Near the end you will be able to choose to continue new set up or use a backup.
