4g wireless tracker is divided into wireless devices and wired devices, wired devices need to be connected to the car power supply to use 24 hours, wireless devices need to rely on their own battery support, depending on the size of the device battery to determine the standby and use days. Therefore, the steps of terminal activation for our 4g wireless tracker are as follows:
One. Install the SIM card
1. Install the SIM card in the card slot of the device (ensure that the SIM card is enabled with Internet access and SMS functions, and there is no chargeback phenomenon). To install the SIM card, open the back cover of the 4g wireless tracker, and then place the SIM card in the direction indicated on the card slot.
Two. Power the locator
Fully charge your GPS locator or connect your vehicle to power.
1. Wiring locator: If you understand the circuit, you can install it yourself, in fact, as long as you find the positive and negative terminals of the car power supply, the negative terminal is very easy to find, the positive terminal is found in the safety box, near the car key switch or directly connected to the battery; If you feel that you do not understand this aspect, you can also ask the relevant technical personnel to install. It should be noted here that the equipment is best connected to normal electricity, so that it is not affected by the car key switch, the power line directly from the car battery; The side of the locator with the light should face the sky, and the side facing the sky should not be close to the metal object blocking the internal GPS antenna to avoid the occurrence of signal instability.
2. Free installation locator: Connect the charging cable of the locator and plug in the locator to start charging. When the locator is fully charged, the charging indicator of the locator will change color or stop blinking.
Note: Different types of positioner charging indicator is displayed in different ways, so it can be operated according to the instructions of different types of positioner.
Three. Activate the locator
Use the vehicle or locator outdoors for a period of time to activate it. Log in to our platform, (PC or mobile) you can see your vehicle information at a glance, including real-time positioning messages, track playback, will be presented in the form of text and lines on the platform, to a large extent to provide your car with security.

Micro gear motor will produce a certain amount of noise when running, the higher the speed, the greater the noise, too much noise will seriously affect the user experience, then how to reduce the noise?
portable pmdc planetary gear motor is composed of rotor winding, armature core, stator, brush, commutator and gear reducer, motor operation process, carbon brush and commutator friction noise, to reduce noise, it is necessary to reduce friction, that is, can reduce noise, Or use the portable pmdc planetary gear motor to reduce noise.
The existence of the brush and commutator will cause a lot of friction, so the noise will be very large, the service life is limited by the material of the brush, the contact resistance of the brush and commutator is also relatively large, the overall resistance of the micro-motor is relatively large, like a large motor, if the speed is too high, it is easy to heat, if the permanent magnet temperature is too high, demagnetization will lead to performance degradation, It has the advantages of convenient speed regulation, low cost and large starting torque, and is usually used in all kinds of electric toys, electronic door locks, adult products, beauty instruments, power tools, small household appliances, smart home and other fields.
The micro gear motor has no brush and commutator device, which greatly reduces the friction service life, is limited to bearings, and the running friction noise will be reduced a lot, but the disadvantage is that the cost is high, the speed regulation is complex, and it is usually used for products with high control requirements and high speed requirements, such as model aircraft, instruments or robots.
Reducer noise reduction attention is divided into: gear accuracy, motor input for plastic gear, helical gear structure
