    Precautions for using two way radio on May 11,2023.
    1. When the intercom is being launched, keep the intercom in the vertical position, and keep the distance between the microphone and the mouth 3-5 cm. The two way radio should be at least 2.5 cm from the head or body at launch. If a handheld radio is carried on the body, the antenna should be at least 2.5 cm away from the body when it is launched. 2, in the process of use do not turn on and off the action for many times, at the same time to adjust the volume to suit your hearing volume. 3. Do not change the parameters of the intercom. Otherwise, the frequency meter function may be confused, which may cause the intercom cannot be used normally and cause unnecessary trouble to maintenance engineers. 4. Only the antennas configured or approved by the original factory can be used. Without the approved antennas, the antennas modified or added with accessories may damage the two way radio or violate the regulations of the Radio Administration Bureau of the Ministry of Information Industry; And may make the communication effect worse. 5, in use, do not use the hand to hold the antenna, do not hold the antenna to swing the machine around here and threre. 6. In use, the antenna of the two way radio can not be screwed off, otherwise it is easy to damage the internal components when transmitting. 7. Do not use damaged antennas. Minor burns may occur if the damaged antenna comes into contact with skin during launch. 8. The radio antenna is compatible with the frequency of the host. Do not use the antenna that does not match the frequency band of the host, which will damage the two way radio and deteriorate the communication effect. 9, two way radio speaker external magnetism is very weak, avoid in the computer, MP3, PDA, U disk and other electronic equipment accessories for a long time emission, wireless electromagnetic wave may have a certain impact on the use of these equipment; Do not use high power close to the human body for a long time. Please keep the distance between your two way radio and the screen such as the computer monitor at a distance of more than 10 cm to avoid magnetization. 10. Please use the original and authentic batteries. 11. All batteries may cause damage or personal injury if metallic conductors such as jewelry, keys, or bead chains touch their bare electrodes. Be careful with charged batteries, especially when carrying them in pockets, wallets, or other metal containers. 12. Charging should be carried out in an environment of 5-40 degrees.

  • The structure of two way radio
    The structure of two way radio on May 9,2023.
    Antenna There are many kinds of antennas, such as two way radio rubber antenna, hand-held radio pull rod antenna, vehicle mounted sucker antenna, FRP omnidirectional antenna, Yagi directional antenna, and suction top antenna. Now many two way radios are full frequency segment, 136-174M, 400-470M, although some small manufacturers known as the antenna is full segment, but it is best to distinguish the antenna high and low segment, for the full segment of the machine, frequency above 450M with 400 high antenna, frequency below 420M, Antenna with lower than 400 is much better, especially when the user on the call distance requirements, more attention should be paid to these. The effect of ordinary tie rod antenna is not big, the length of rubber antenna is a great deal of attention, not the longer the better, if the effect is significant, MOTOROLA and other international brands why not do it? The gap between the car suction cup antenna is very big, good to hundreds of pieces or even more than one thousand yuan, the most cheap one is just 40 yuan, it is recommended that we sell more than one hundred antenna, quality assurance, sensitivity is also higher, the distance of the sales of the platform also has a greater help, or that sentence, a good horse with a good saddle. Channel value Some two way radios have displays and some do not. Two way radios without displays generally have 16 channels such as Senhaix 1430, 15 regular channels and one scan channel. Two way radios with display screens generally have 99 or 128 channels such as SenhaiX 8800 and SenhaiX 8600. Moreover, two way radios store 99 or 128 channels, maritime two way radios are generally 128 channels. Status indicator The status indicator of the two way radio refers to the two status indicators of transmitting and receiving. Under normal circumstances, the indicator is out when the two way radio does not work, the indicator is red when transmitting, the indicator is green when receiving, and the signal is not good when the two way radio receives, the green indicator is not always on, but irregular "jitter". If the two way radio battery is low and it is in standby state, the red indicator blinks, indicating that the battery is low. You need to replace the battery. If you do not replace the battery in time, a beep will beep when you press the launch button of the two way radio. Horn Horns of two way radio have several calibers, the sound quality of the speaker and the size of the sound cavity has a large system, the sound quality of the big two way radio is better than the sound quality of the small one. Battery Batteries are an important part of a two way radio. A good battery for a two way radio is like a good  saddle for a good horse. Walkie-talkie batteries can be divided into nickel cadmium battery, nickel metal hydride battery, lithium ion battery.

  • How far is the actual communication distance of two way radio?
    How far is the actual communication distance of two way radio? on 2023-05-05
    Radio as a wireless communication tools, and mobile phone contrast has its own advantages: in the set of one-to-one, one-to-many communications, especially the characteristics of the one-to-many is ordinary mobile phone can't compare. With the continuous improvement of the basic functions and the expansion of the main uses of two way radios, two way radios are also widely used in the military, public security organs, security, rescue, public utilities and other government departments. In addition to its application in professional fields, two way radios are also gradually entering People's Daily life. They can also be found in civil occasions such as dispatching, security, property management, construction sites and hotels in daily life.Many customers who have just contacted the two way radio often ask, how far can the radio call?There is a problem about the communication distance of the two way radio, in fact, mainly depends on the communication distance, push power, two key factors, today we will talk about how to know how far the communication distance of the two way radio is? 1. Communication spacing Usually communication spacing within 2-3 kilometers can be regarded as short distance communication, relative to individual users, can buy civil radios. Compared with enterprise customers, they can purchase low-power radios by applying for them. If they want to ensure the actual effect of communication, they can choose professional common radios. If you need to communicate within the city and the communication distance is within 3-10km, you can consider buying a professional walkie-talkie. The Senhaix GT-10 is a good choice. If it is further away, it is best to use the base station power and handheld radio communication, or the vehicle-mounted platform and vehicle-mounted platform communication base platform. We can use the relatively large power of the vehicle-mounted radio. If customers need longer distance or better communication quality, they can use cluster interphones if they do not have their own professional digital trunking . Professional digital trunkings are supported by the wireless communication Internet, so the communication distance is relatively far. Because the two way radios need the support of the Internet, if the two way radios are taken off the Internet, just like the mobile phones are taken off the Internet, even if the calls are face to face, they cannot be made. 2. Sending power Compared with the wireless communication machine equipment, the size of the sending power is particularly important. The same wireless devices, the high sending power products and low sending power products are different from price. At the same time, the difference of sending power also directly affects the stability of wireless network data transmission.Therefore, pay attention to the size of the selected machine and device sending power, is also an important part of the whole process of selecting wireless devices. At present, some of the push pow...

    First, What is the meaning of two way radio programming The traditional analog radio the machine at the same frequency is generally interworking, but if there is a frequency phenomenon after the need to modify to adjust the frequency and CTCSS, this is the need to programming line to link into the radio. When programming the machine, the role of the programming line is to convert the level, and the popular tap is to convert the information sent by the computer into the information that can be read by the two way radio, just like translation Second,problems of two way radios in the programming 1. The two way radio installation file cannot be programmed An error caused by packaging naming may have prevented users from using the installation file. When packaging software, do not use Chinese names or full-angle symbols, use English half-angle characters. 2. When there are errors in the old software, the new software can not be used normally. May be the old software error data programmed into the machine, at this time with the new version of the software to read the machine data will cause errors, encounter this kind of situation, reset the machine or on the existing error of the two way radio first perform a programming operation, (before editing do not read the existing error into the two way radio, but can read the original software has not programmed) 3. After the upgrade software is replaced, the saved data file cannot be opened If the new version of the software does not support data saved by the Japanese version of the software. You can obtain saved data in the following ways:. Use the old software to read the data and program it into the two way radio (the two way radio that has been programmed can ignore this step)· Read the data from the two way radio. Attention: It may cause some unexpected errors, we recommend that it should not be used in this way. The way to do that is to program a new piece of data. 4. After the software is replaced or upgraded, data is read out, causing an error in the programming software. After initializing the two way radio, read data or directly edit data to program (program once first) 5. After the software is replaced or upgraded, files cannot be saved or an error occurs after reading the two way radio. Read data after initializing the two way radio or directly edit data to be programmed (program once first). 6.

  • Why do we need an explosion-proof radio?
    Why do we need an explosion-proof radio? on 2023-05-02
    Literally,the general people rarely contact explosion-proof radio, can only merely understand the use is explosion-proof function, can be applied to the explosion-proof area, as for what principle, explosion-proof radio specific what characteristics are not known. Explosion-proof radios refer to two way radios used in different flammable, explosive, dust and other environments according to different explosion-proof certification levels. Explosion-proof radios are attached with Ex explosion-proof certification mark, indicating that the product has passed the national explosion-proof testing agency certification, can be used in specific explosive gas environment. The principle of explosion-proof radio: Explosion often brings great loss of life and property. Preventing the release of combustible materials, which is often the cause of explosive conditions, and preventing the creation of effective ignition sources are widely used methods to reduce the risk of explosion. And the use of correct equipment can be more effective prevention. An effective source of ignition may be one or a combination of: lightning, open flames, excessive surface temperatures, electric arcs or sparks in electronic equipment, sparks caused by different potentials, mechanical sparks (friction or collision), electrostatic discharges, radio-frequency radiation, and associated radiation (lasers). Why do you need an explosion-proof radio? From the above we can see that the use of explosion-proof radio in special occasions is a necessary communication equipment, then explosion-proof radio, is a function of explosion-proof radio, and use is more practical than the general two way radio.        Ordinary mobile phone calls can only be one-to-one, while two way radio supports one-to-many call mode, which can highlight its advantages in the work scene of personnel scheduling, and well solve the problem of division of labor and decision. Explosion-proof radios can talk without any network support, and no call charges are generated. They are suitable for relatively fixed and frequent calls. In some special working background environment, such as very noisy production workshop, pharmaceutical workshop, the voice of the walkie-talkie is clear, convenient communication, and the two way radio can achieve a hundred calls, very practical! The difference between explosion-proof radios and ordinary radios Let's start by understanding what an explosion-proof radio is. This type of two way radio mainly refers to the ability to work in the environment of explosive gas, rather than itself can resist explosion. At present, it is mainly used in harsh environment and dangerous combustible gas or dust environment, such as petrochemical, coal, chemical, thermal power, food processing and other industries. Our commonly used analog and digital two way radios mainly rely on electromagnetic wave to transmit signals, and electromagnetic wave transmission mainly uses the continuous conversio...

  • Several significant advantages of digital radios
    Several significant advantages of digital radios on April 26,2023.
    Two way radio in the design technology, can be divided analog radio (that is, we common traditional walkie-talkie) and digital radio. Analog radios modulate the stored signal to the transmission frequency of the two way radios, while digital radios digitize the voice information and transmit it in the form of digital encoding, that is, all the modulation on the transmission frequency of the two way radios is digital. Digital radios have the advantages of countermeasures, clear voice, high confidentiality, narrow channel bandwidth, and stronger data transmission ability.In the global high-end market two way radio, SenhaiX communication solutions to fully meet the business needs of commercial customers, in the process of analog to digital plays an important role, has been for hotel properties, large business, major events and other users to provide a clear and reliable digital communication solutions. The advantages of digital radios over analog radios are shown in the following aspects: First, the traditional analog radio is a communication mode in which the voice, signaling and signal are modulated to the carrier frequency of the walkie talkie by means of continuous wave and optimized by amplification. It has the advantages of mature technology, perfect system and relatively low cost. Second, digital radio is the voice signal digitization, in a specific digital encoding and a specific form of baseband modulation, and the use of digital signal processor to optimize the digital communication mode. First, spectrum resources can be better used. Similar to cellular digital technology, digital radios can load more users on a given channel and improve spectrum utilization. This is a solution to frequency congestion.Second, improve the quality of calls. With in-system error correction capabilities, digital communication technologies can achieve better voice and audio quality over a wider range of signal environments than analog radios, receiving audio with less noise and clearer sound. Third, improve voice and data integration, and change the weakness that control signals decrease with the increase of communication distance.
