Things you have to know about Motorola walkie-talkies

Date:Dec 31, 2020

There are some functions of Motorola walkie-talkies that you may have known and used for a while, but some of them are even the first time you know them. This article will take you to re-acquaint you with the powerful functions of Motorola walkie-talkies and improve your sense of use.

 

1. Audio level

Compared with other walkie-talkies, the sound of Motorola walkie-talkies sounds very loud, with low distortion and high restoration. This is because Motorola uses a series of unique and unique audio processing technologies that can filter out noise in communication and improve the call. The quality makes the received sound sound loud with good fidelity.

Audio level is also one of the basic functions of audio processing to ensure high-quality voice. The walkie-talkie is usually in motion or in a complex dynamic environment, and the sender’s voice is not so easy to maintain steady. When the other party speaks very lightly or very loudly, the receiver's intercom will automatically adjust to ensure sound quality and maintain a stable volume. In the call mode, once the voice detected on the walkie-talkie is received, this basic function can automatically start to adjust the voice level in the received data signal, so that the user can get a better voice experience.

2. Forced transmission suspension-coding

Instant messaging is the advantage of walkie-talkies. Everyone is talking at the moment of an emergency, but it is impossible for the receiver to listen to two or more voices at the same time. The performance of the receiving walkie-talkie is that the decoding fails and nothing can be heard. Therefore, this Information content that is very important at all times may not be successfully sent. In order to better ensure that important people in an emergency can send important information content, you must use this unique basic function of Motorola: forced transmission suspension-coding, that is, actively and forcibly terminate all ongoing calls on other walkie-talkies (forced in Basic functions) to ensure the most important information content delivery.

Normally, walkie-talkie calls include three method steps: application for channel processing, speech, and channel release. Only when the channel is idle can the application for the call be approved. Therefore, the call is usually short, there are questions and answers, and no long talk. If you don't follow this standard (or in an emergency situation), it is likely to cause communication disorder. This function avoids this kind of situation and ensures that important information is delivered in time.

 

3. Enhanced noise reduction

This basic function enables the walkie-talkie to have a stronger ability to suppress external noise, thereby improving the clarity of the target voice, and greatly improving the user experience of the walkie-talkie. Compared with walkie-talkie users, it is the most basic requirement to clearly transmit their voice to the other party. And with external noise suppression, walkie-talkies with stronger noise suppression capabilities will provide users with better voice quality.

The basic function of enhanced noise cancellation is very important compared to users who are noisy in the working environment, such as traffic police, processing plant employees and other noisy environments. In a noisy environment where the surrounding noise exceeds 80 decibels or more, especially in the environment of blowers and boilers in processing plants that are 90 decibels or higher, walkie-talkies without basic functions of noise suppression may transmit the noise to the other party together with the target voice. In turn, the sound from the walkie-talkie is covered by noise, making the other party unable to hear clearly. Motorola walkie-talkies with enhanced noise cancellation capabilities can reasonably and effectively suppress and process external noise, reduce noise intensity, increase target voice intensity, and provide users with clear and reliable voice communications using excellent methods.

4. Silent mode

Each walkie-talkie has the basic functions of emergency calling and receiving emergency calls. After the emergency call is initiated, all normal conversations or transmission data of the walkie-talkie will be occupied by the advanced emergency call. At this moment, it may affect the basic call and data transmission of walkie-talkie users. Compared with some users with special working environment, this has a great impact on work.

At this moment, with the help of the mute emergency call mode, the sound and light effect prompts of emergency calls can be shielded, and all normal voice or data communications of the user are not disconnected. Only after the user presses the PPT button, the silent mode is cancelled, and the emergency call sound and light effect prompts are displayed on the walkie-talkie again.

This basic function faces some users who are not sensitive to emergency calls to ensure that all normal calls and transmission data of the walkie-talkie are not affected, and all normal voice calls and transmission data of users are ensured.

 


5. Fall alarm

When users are in a dangerous production environment, they can also use the basic function of falling alarm. When danger occurs, the walkie-talkie can use pre-defined criteria (such as the walkie-talkie in an inclined direction for the duration, continuous movement within the duration, and static motion within the duration) to send an alarm to the overall target walkie-talkie or dispatcher. The users who receive the alarm promptly check the users of the walkie-talkie who alarmed for the fall. After the event is resolved, the walkie-talkie for the fall alarm will be released.

With this basic function, if a walkie-talkie user operating in a dangerous environment loses consciousness in a safety accident, the walkie-talkie with the basic function of falling alarm triggers an alarm and reports it to the administrator in time to ensure the life of the operator.

 

6. text to speech

When you are unable or inconvenient to query the content of text information (such as the walkie-talkie does not have a display screen, and the user's hands are occupied when working), you can also set the text-to-speech function. The walkie-talkie can also automatically convert the received text message content into voice for broadcast. More applicable work scenarios: With this function, intercom users working at the grassroots level, if they receive text messages, they do not need to stop their current work. The intercom will automatically convert the text to voice broadcast, which is beneficial to improve work efficiency.

7.The use of walkie-talkies is prohibited/remote control monitoring

The first step introduces the prohibition of remote control of walkie-talkies that require authentication. It allows the user to use the menu to initiate a walkie-talkie prohibition instruction to the overall target walkie-talkie. The overall goal of the walkie-talkie will be to prohibit the use of all user interfaces (including all LED indicators, backlights, prompts, and PTT user input), ignore the emergency alarms and received data messages of the walkie-talkie or external equipment, and make the walkie-talkie or external equipment receive voice Silent mode, and does not allow data or commands to be transmitted from walkie-talkies or external devices.

Using this function, you can also prohibit all improperly used walkie-talkies, such as lost or stolen walkie-talkies, to ensure system security. The remote control monitoring function of the walkie-talkie that requires identity verification allows the user to use the menu to initiate a remote control monitoring application to the overall target walkie-talkie. After the application is successful, the microphone and transmitter of the overall target walkie-talkie will be activated to facilitate remote control of monitoring.

This function can also activate the microphone and transmitter of the overall target walkie-talkie within a period of time, and monitor the calls created on the overall target walkie-talkie, without the overall target user knowing nothing about it.

 



8. emission suppression

Similar to the flight mode of a mobile phone, the walkie-talkie enters the radio silence and only accepts no transmission (not including Bluetooth);

 

9. response suppression

Wireless communication response suppression is an extension of the wireless communication transmission suppression function (please read in conjunction with the previous one). This function can help walkie-talkie users avoid the risk of being positioned as much as possible (for example, using GPS) or the risk of being monitored by remote monitoring. When the intercom user activates the response suppression function, the intercom only allows the user to use voice calls, CSBK calls, and data message calls (for SMS, work notifications, telemetry, etc.), and all other types of transmission include all ACK, ARS, GPS Etc., the transmission including third-party applications will be blocked to prevent the relevant voice or data information from being received by third-party personnel.

This function can prevent the walkie-talkie from being monitored, monitored and located, and prevent the sensitive information content of the walkie-talkie user from being transmitted. This is a very important function compared to some special walkie-talkie users. You can also use programmable buttons or GPIO to activate or deactivate this function. This function is mainly used for land mobile radio communication (LMR) related calls, and is not applicable to actual operations such as Bluetooth or Wi-Fi that can be independently enabled or prohibited. This function is mainly used for the following digital system configurations, including: direct mode/dual capacity direct mode, single-frequency repeater, traditional single-site and IPSC, single-site cluster.

 

10 single station/multi station cluster

Capacity Plus (Mult iSite) is a multi-site cluster system promoted by Motorola. The system is characterized by relatively stable operation, with weakened faults, and no dedicated control channel (all channels can be used for voice services to improve the overall cost-effectiveness of the system). This system mainly solves the geographical limitation and capacity limitation of traditional intercom systems.

When you buy a walkie-talkie with this function, your walkie-talkie has been authorized to use Motorola's Capacity Plus (Multi Site) cluster system. When you use this system, your walkie-talkie will have more system functions , Your system will have stronger scalability.
