What are the functions of the car navigation instrument?

1. Location upload: The satellite positioning instrument will upload the parsed position to the background server through the mobile Internet.

2. Real -time positioning: The satellite positioning instrument can collect information about satellite in real time and analyze the information.

3. Session function: After the satellite positioning instrument is positioned, the time accuracy can reach nano seconds.

4. Oil break function: The satellite positioning instrument can remotely break the oil. After the oil is broken, the vehicle will be turned off and will not be started.

5. Speed alarm: You can set up speed warning prompts in the navigator. The alarm will be alarm during the prescribed road section and prescribed operating time, and the bee singer installed in the car makes a noise.

6. Automatic navigation: voice prompts to turn, turn around, etc. The screen shows the information of the map, the location of the car, the speed of the car, the distance between the distance of the destination, and the departure of the driving track also provides a re -planning route function.

7. One -click alarm: The satellite positioner supports the one -click alarm function. In emergency situations, you can send alarm for help.

8. electronic dog function: Through the speed measurement information recorded in the library, the pronunciation reports prompt early warning information in advance.It should be noted that if there is no recorded information point of the ground gallery, the prompt will not be issued, and some car navigator electronic Dogs do not have its own radar chip's unable to warn the flow speed measuring instrument.

precautions for the use of car navigation instrument electronic Dogs

1. It is best to mobilize the car first, and then insert some cigarettes.After the navigation is over, unplug the cigarette lighter, and then insert it after the car is launched next time. This will help protect the machine battery and extend the service life of the battery.

2. After use, follow the order of shutdown: close the page first, then shut down, and finally unplug the plug.Some car owner pictures are convenient, and the plug is pulled directly after use. It never shuts down.

3. Do not put the electronic dog in the sun for a long time and expose the sun. The larger temperature difference not only affects the battery life, but also affects the touch sensitivity of the LCD screen.It is best to put it away after use, do not put it in a prominent position on the car, so as not to provoke a thief.

4. It is best to charge for about 10 hours in the first three times, so that the battery power storage capacity is maximized.

5. Do not let the navigation screen contact sharp objects.

6. The electronic dog function of the navigator is not necessarily accurate and perfect. Some sections do not prompt speed warning, but there are mobile speed measured vehicles for radar speed measuring. Therefore, you cannot just rely on the navigator electronic Dogs to reverse the speed.Of course, to abide by traffic order and control speed in the specified range is the safest.

7. Pay attention to the update of the internal data of the navigator and the upgrade of the electronic dog to avoid the warning prompts cannot be received in a timely manner due to the inadequate data update.

Round backward, change another way to walk

The way backward is the most appreciated by the lumbar spine.When walking backside, the legs move backwards alternately to enhance the strength of the rear muscles of the thighs and the waist and back muscles, which enhances the elasticity of the lumbar ligament, just like the lumbar spine protective Belt.The functional recovery of bones, muscles, and ligaments can not only enhance the stability of the lumbar spine, but also reduce the pain of the lumbar spine or even disappear.When walking backwards, it is best to take 60 steps per minute 100 steps, 10 minutes each time.

exercise the lower body muscle group

Strong legs can effectively divide the burden on the back of the waist to prevent and relieve back pain.swimming, especially breaststroke can mainly practice these muscle groups.In addition, swimming can also ensure the nutritional supply of intervertebral tissues, maintain its elasticity, and improve the ability of spine resistance.
