Introduction: Driving on the road, in addition to listening to your own music to cultivate your sentiment, then you can listen to the radio and have a good time. By the way, you can learn about the real-time road conditions.
But this car radio is not worry-free, the signal is poor, and sometimes it can only receive two stations and it is not clear...Many riders are very confused, how can they not receive the number, let alone the three-dimensional Sound!
★Analysis of the reason why the signal cannot be received
1. The compact SUV radio receives broadcast signals through an antenna, and the signal reception quality is affected by many factors.
For example, in mountainous areas, tunnels, tall buildings, magnetic fields or poor signal areas, the signal is blocked or interfered, which makes the radio unable/difficult to receive signals.

2. In bad weather conditions such as cloudy, rainy, foggy, and snowy, or in non-outdoor areas such as indoor garages and underground parking lots, satellites cannot be connected.
The signal in densely populated areas with high-rise buildings will also become weaker.

★Solution
1. As long as there is no environmental interference, the radio can be received normally, indicating that there is no problem with the radio.
2. In some areas with weak signal, you can manually adjust the frequency band to receive the sound, but there may be noise at this time.
3. In any case, the radio cannot be received, please go to the local Geely 4s store to check whether the radio and antenna are normal.
★The car radio has no signal and noise. What is the reason?
Radio is an electronic product that appeared in the 1950s. The sound of radio stations has grown up from generation to generation. As people born in the 70s and 80s, the radio is still the only electronic entertainment product in childhood.
Although mobile entertainment has become the mainstream now, the radio is still a favorite of many people. The music, opera, cross talk sketches on the radio, and real-time traffic information in the city still bring a lot of fun to driving.
But on the way of driving, you will encounter more or less when it is difficult to receive some of your favorite radio stations, which will bring you some unpleasantness when driving. Today I will list some tips on wireless radio for everyone who is worried about driving. Bring a touch of care.
The dfsk 4x4 van radio frequency (AM: 520-1629KHz, FM: 87.5-108MHz), the signal of the wireless radio is sent and received by means of electromagnetic waves (as shown above).
Electromagnetic waves propagate through the ground and the air. The principle of electromagnetic wave propagation is that electric and magnetic fields are superimposed on each other. In short, a magnetic field can be formed around the current.
the midline of the formed magnetic field then forms a current, which alternates periodically, propagating the signal to a certain direction in space, so that we should know that the medium of electromagnetic wave propagation should be the electric field and the magnetic field.
Although it is invisible and intangible, it will be affected by clouds (charged) in the air, buildings, 220V high-voltage wires or substations, high-power electrical equipment, large metal objects, mountains, humidity in the air, smog, overpasses, etc. Blocking or attenuating the signal, resulting in signal instability.
It is the instability of the wireless signal that sometimes makes it difficult for you to listen to your favorite radio station or there is noise when listening. Some radios will indicate that the signal is weak. When this problem occurs, you should carefully observe whether the surrounding environment is there. The following situation.
Such as: remote mountainous areas, at the foot of mountains, rural areas (the radio transmitter is in the city), there are large trucks around, there are substations or high-voltage lines around, near airports, under overpasses, urban bridges or tunnels, or the weather is thunderstorm, heavy snow, and fog. Haze, cloudy, etc.
