Notes
This model can only be connected to the network of China Mobile or China Unicom, and the card cannot be recognized when inserted. Be sure to insert or remove the card when the power is off. The light is always on when the card is not inserted and the card is powered on. After the card is inserted, the light starts to flash after it finds the network in about seconds to seconds. At this time, the random software can be started. After-sales service includes guaranteed returns within a day, monthly replacement, and one-year warranty.
The return and exchange freight charges will be borne by each individual. The chosen courier company is SF Express for places where SF Express can reach, and YTO or YTO for places where SF Express cannot reach. Product Advantages
The peripheral circuit boards of industrial mobile phones are all developed and designed by ourselves. The main components are civilian industrial-grade chips and all-solid capacitors. Because the operating frequency is 100%, there are special design optimizations for stability and anti-interference.
The stability of industrial mobile phones is our first consideration. There are many reasons that affect stability and SMS sending success rate. Power quality and antenna quality are also crucial. Through years of research, the quality of the power supplies and antennas we selected are first-class. The power supply adopts domestic brand power supply, and the failure rate is one in ten thousand. You can weigh the weight. The suction cup antenna has strong suction power and the length is above. The main technical parameters are as follows: gain B, standing wave ratio R, input impedance polarization mode r, vertical maximum power operating temperature r ℃～+℃. Each product has been tested and signaled before shipment. Value inspection is performed once during the production process after final assembly and again before shipment. Those who pass the test will be labeled with the test engineer number. Excluding software factors, the industrial mobile phones produced by our company can work stably for more than three hours every day for more than a year. If your test fails to meet this standard, you can return or replace it. Frequently Asked Questions
Which is better, serial port or B port? If you are connecting to a desktop or server, it is recommended to choose the serial port, R data cable You can tighten the fixing screw, which is relatively strong. If you are using a notebook, it is recommended to use the B port for easy plugging and unplugging.
Which one is better, short stick antenna or car suction cup antenna? The signal values of these antennas are the same, they are all in between. If you use it on a desktop computer, it is recommended that you choose a suction cup antenna, which can be adsorbed on the chassis and is very strong. If you use it on a laptop, it is recommended that you use a short stick antenna, which does not take up space.
Is there a power supply problem with B? Is B not as stable as the serial port? The energy consumption of B is below, and there is no problem with the power supply of B. The reason why B feels less stable than the serial port is because the early driver of B was not perfect enough. After several years of driver upgrades, the current B interface is running very stably
