How to change the frequency or change the platform of the public network trunking intercom

The public network is not a channel but a group, and all group operations are background air writing frequency, but professional machines are changed with computers, and find a walkie-talkie to repair.

The shop is easy to get done.

The public network trunking intercom is different from the full-duplex of ordinary mobile **.

The communication mode is also different from the simplex communication mode of ordinary walkie-talkies, but belongs to the half-duplex communication loaded with complex control signaling, and should be used according to the following method:

Sending and receiving communication can not be carried out at the same time, when using, you must hold down "PTT" to talk, release "PTT" to listen, and before a call is established, the trunking intercom also uses a signaling process to apply for communication to the system, therefore, the user who initiates the call needs to wait for 1 second after holding down "PTT" for the first call before speaking. At the end of the call, the user who initiated the call should press the delete button once.

The wire is removed so that the system can recover the communication channel in time and save system resources.

Read the operation manual carefully and be familiar with the buttons and functions of the public network trunking intercom. Check whether the antenna is damaged and whether it is tightly installed before turning on the machine, do not turn on and off multiple times during use, and adjust the volume knob to the desired position at the same time.

If you find that the call effect is not good, you should change the direction or position, minimize the building obstruction between the walkie-talkie and the base station of the trunking system, and when using it indoors, it is best to be close to the window.

You can switch operations, but the way of switching fleets on different public network platforms is different, and the switching is a bit troublesome. Specific ways to send private messages.

Hello! There are three main switches or knobs used in walkie-talkies. The knob on the left side of the top is the switch, and the volume can also be adjusted, and the knob on the right side of the top is responsible for adjusting the corresponding channel; The button on the side of the walkie-talkie is the send button.

2. When turning on, rotate the switch knob clockwise, there is an obvious start-up sound and the indicator light will flash green once, and then adjust to the appropriate volume. 3 Then adjust the walkie-talkie to the same channel, if there is frequent noise, it may conflict with other people's walkie-talkie channels, you can switch to other channels to avoid interference. 4 When receiving communication from others, the indicator light will flash green.

5. When you need to speak, press and hold the send button and then start communication, and release the call button in time after the phone is finished. 6. If you use a cradle charger for charging, the charger indicator shows red and does not flash, it means normal charging, and when it turns green, it means that charging is complete. If the indicator light flashes, it is likely that the walkie-talkie is not in good contact with the charger, and you need to replug it into the charger.

Summary. Dear is happy to answer for you! 1. First of all, you need to prepare the public network cluster walkie-talkie to be logged in, and the computer for its use, and connect the computer to the same LAN as the public network cluster walkie-talkie; 2. Open the browser in the computer, enter the IP address of the public network cluster intercom, and enter the login page; 3. Enter the username and password, and click the "Login" button; 4. If the user name and password entered are correct, you can successfully log in to the public network cluster intercom; 5. If the user name and password entered are incorrect, it may be that the password is incorrect, or the authority is not enough, please re-enter the correct user name and password, or contact the administrator of the public network cluster intercom.

There's no way to upgrade this

Other walkie-talkie common sense:

1.During the use of the public network walkie-talkie, you can not twist the antenna or even bend the antenna, and you must not use the antenna that is unqualified, not matched, and broken by the glue, otherwise it will not only affect the call quality of the public network walkie-talkie, but also burn the public network walkie-talkie in serious cases, and do not pick up the public network walkie-talkie by grabbing the antenna.

2.The public network walkie-talkie can be charged for 6-8 hours each time (3-4 hours for fast charging), please don't forget to turn it off when charging, so as not to damage the walkie-talkie when the voltage is unstable, stop charging after the time is up, do not overcharge, so as not to affect the battery life.

3.In the potential atmospheric environment or occasion, unless the public network walkie-talkie has passed special certification (such as explosion-proof walkie-talkie), the walkie-talkie must be turned off. In a potentially atmospheric environment, an electrical spark can cause a fire or fire.

Lazheng 4When the public network walkie-talkie is transmitting, keep the public network walkie-talkie in a vertical position, and keep the distance between the microphone and the mouth centimeters; When transmitting, the public network walkie-talkie is at least centimeters away from the head or body.

5.During the use of the public network walkie-talkie, do not turn on and off the computer multiple times, and adjust the volume to a volume suitable for hearing.

6.The machine should be shut down immediately after water ingress, and the battery should be unplugged immediately, the water should be thrown out vigorously, and it should be dried in a ventilated and dry place, and returned to the factory for maintenance as soon as possible.

7.Do not disassemble the machine for maintenance, the walkie-talkie is different from the mobile phone, and it is difficult to repair it without professional technology and equipment.

The public network is not a channel but a closed band, and all group operations are background air write frequency operations, and dealers need to write multiple channels to use the button to switch, so it is generally not FM.

The working principle of the public network car Jing cluster walkie-talkie:

1. The public network walkie-talkie is a technology that transmits the voice signal through the data channel of the mobile phone network signal to realize the intercom call.

2. It solves the problem of intercom real-time and PTT signal error-free transmission, so as to solve the problem that the traditional walkie-talkie is constrained by the transmission power and antenna sensitivity, and the intercom call distance is short, and realizes the purpose of national and global intercom.

3. Typical applications include cross-urban and inter-provincial logistics fleets, wireless communication between large enterprise branches, and unified wireless command and dispatch of large-scale public security and urban management.

4. The public network walkie-talkie has innovated the radio signal coverage solution of the traditional high-power repeater.

The steps to set up a host are as follows:

1.First of all, make sure that the walkie-talkie is already in working order.

2.Follow the instructions in the walkie-talkie's manual to find the "Network Settings" option of the walkie-talkie.

3.In the Network Settings interface, select the Set Host option and follow the prompts.

4.When you set up a host, you need to enter network and identity information, such as IP address, subnet mask, and gateway. This information can usually be found in the LAN management device or obtained through the carrier.

5.After the input is completed, save the set up and restart the walkie-talkie.

It should be noted that the way to set up the host of walkie-talkies from different manufacturers may be slightly different, so please be sure to read the manual carefully before operating, and follow the guidance for careful operation. In addition, in the process of equipment networking, the stability and security of the network should be ensured to ensure the normal operation and communication quality of the walkie-talkie.
