The problem is urgent! Thanks 1 50

TV satellite signal receiver.

After connecting the machine, press the information button, at this time, only the signal strength is more than 70%, and the signal quality is zero or very small, indicating that the connection is correct. It's just that the azimuth and elevation angles are not adjusted well. Use the star guide to determine and estimate the azimuth and elevation angles of the received satellite.

First find a satellite program with a strong signal (the program parameters of several satellites are stored in the machine when leaving the factory), such as Beijing Satellite TV with a strong signal here. Hunan Satellite TV also has a strong signal. Press the information button, and the Asian 3s azimuth is in the southwest direction.

First, determine the approximate position of the antenna azimuth. Then adjust the elevation angle, the elevation angle is not fixed at first, repeatedly adjust the elevation angle size, after each elevation angle, rotate the azimuth angle, and see if the signal quality has changed, as long as there is a small change to capture the satellite signal, and then carefully adjust the azimuth angle and elevation angle, when the signal quality reaches more than 30 percent, you can watch the program. Finally, it is necessary to adjust the polarization angle of the lower high-frequency head and the focal length of the high-frequency head.

The polarization angle is equal to the satellite diameter minus the local diameter. The zero degree of the high-frequency head is in the horizontal position. As long as you adjust carefully, you will be in the best condition.

With a 1.5-meter antenna here, the signal quality of Beijing Satellite TV can reach more than 70 percent. After adjusting, press the exit button and it's OK. Satellite program parameters are available at http**.

We call it the cauldron here.

You don't need to register at all, you can receive it directly.

That's stealing satellite signals. Be careful not to get caught.

This thing is called a pot antenna.

A digital decoder is required.

A digital decoder looks similar to a VCD. It wouldn't work without this thing

It's a TV satellite receiver that can receive radio, that is, audio, that is, you can receive **, that is, TV programs Registration code is not Oh It is the password to search for more programs, generally operated by the equipped remote control The different manufacturers, it is recommended to ask the people you got (or the manufacturers you bought) to ask, and the general sellers are very clear

"Squeak" and "can't start" should be two separate problems "Squeak" The most common problem is that the belt is used for a long time in summer, due to the high temperature, the vehicle is often used, the friction coefficient of the driving wheel and driven wheel of the belt and the engine is reduced, and the visual inspection will find that the surface of the belt is a little bright, especially when the load and the air conditioner are used to accelerate It is generally poured on it with some clean water when the engine is idling. Splashed to the belt part, this needs to go to the 4S store with a special tool to deal with, I don't know if the landlord is this kind of phenomenon.

Regarding the problem that "can't start" should be the battery, it is recommended to press the horn first, make sure that the sound is loud, turn off all electrical appliances, especially do not lift and lower the power window, this is the most power-hungry electrical appliance in the car, open the cover, open the battery wiring cover, it is best to hit the battery binding post with an insulated hard object, and then get on the car to start, there is generally no problem.

Question 2, the upper bottom is 17 meters, the lower bottom is 33 meters, and the height is 11 meters, and the sum of the upper bottom plus the lower bottom of the area is divided by 2, so the area is 275

Question 3, 10 roots in the most robbing layer, 20 roots in the bottom layer, one difference between each adjacent two layers, so 11, 12, 13, 14 15 16 17 18 19 20, a total of 165, a total value of 82,500 yuan.

The formula = sin( 3)-sin0 = the root number of half of the number three.

In step , a is used as the dividend and b c is used as the divisor.

, with a b as the dividend and c as the divisor.

Hope it helps.

It's all right, but you're not sure about the length of the horizontal line in the formula.

The practice is to have a long horizontal line above.

The practice is to make the horizontal line below long.

Which one do you want?

The radius of the circle is 5, subtract half the area of the circle from the area of the rectangle.

The second big question, the second, the third, and the fourth can all be proportional!
