How to understand the meaning of digital walkie-talkie functions?-Part 2

When using walkie-talkies, we often talk about FPP, Monitor, Scrambler and other functions. Do you know what these functions mean? Today, Retevis Solutiosn will take you to understand the meaning of the functions in the digital walkie-talkie.

What is DTMF(Dual tone multi frequency) function of digital walkie-talkie?

Dual-tone multi-frequency, composed of high-frequency group and low-frequency group, each of which contains 4 frequencies. A high-frequency signal and a low-frequency signal are superimposed to form a combined signal, which represents a number. DTMF signaling has 16 codes. Use DTMF signaling to choose to call the corresponding walkie-talkie.
TONE/DTMF selective calling function: Use 2-TONE or DTMF signaling to selectively call the corresponding walkie-talkie. It is a kind of Signaling, you can remotely setting other walkie-talkies through numbers. Like PPT-ID, group call, remote kill activation, selective call. Many Retevis radios have this DTMF function,like Rtevis RT3S RT52 RT53 RT80 RT54 etc.

What is 5-tone and 2-tone function of digital walkie-talkie?

2-TONE: Two-tone signaling, composed of two audio signals, A Tone + B Tone. Send A Tone for a period of time, and then send B Tone after a period of time. Use 2-TONE signaling to choose to call the corresponding walkie-talkie; 5-tone signaling has the same function as 2-tone signaling, except that it consists of five frequencies. It can support emergency alarm, ANI identification, selective calling, remote shaking, data transmission during the use of the walkie-talkie. This function is very suitable for the security field. Like Retevis RT50 RT72 is 5-tone. Like Retevis RT72 support 2-tone.

What is ANI function of digital walkie-talkie?

The ANI identification function means that the radio can transmitte the name of the set radio. On the premise that other radios also support this function, look at the radio screen to know which radio is sending the signal.

What is Battery save function of digital walkie-talkie?

Power saving function Battery save power saving mode. The automatic power saving function, in order to save power and extend the standby time, the walkie-talkie will work in a period of time off and on for a period of time without transmission and reception or key operation for a period of time. The method is called the power saving method. Reduce empty time and power consumption, so as to extend the working time of the radio. This function is very useful in business and outdoor use. Many Retevis Radios have this function, like Retevis RT81 RT50 RT52 RT53 RET54 etc.

What is Low battery alarm function of digital walkie-talkie?

Low battery alarm Low battery alarm / Low battery alarm. When the battery power drops to a preset value, the "di-di please charge" prompt sound will sound every ten seconds. It is convenient for you to arrange time to charge or change the battery to continue using. This function is very useful for commercial digital walkie-talkies without a display screen, because you have no way to know the battery level, and the voice reminder can inform you to charge in time to avoid low battery or sudden power failure affecting the normal use of the walkie-talkie. Retevis RT52 RT53 RT43 all have this Low battery alarm function.

What is High/Low TX power function of digital walkie-talkie?

High/Low TX power selectable power adjustment, high and low power switching, to meet the power needs of users at different distances, more energy-saving and power-saving. Theoretically, the greater the power, the longer the call distance, but the larger the power, the higher the power consumption. When it is lowered, the power can be manually adjusted to save power. Retevis RT54 RT43 RT53 RT80 etc all have High/Low TX power selectable functions.

What is the Single signal 1750MHz function of digital walkie-talkie?

Transit pilot frequency, 1750MHz, 2100MHz, 1000MHz, 1450MHz. It is a single tone pulse signal. Used to wake up the repeater. Like Retevis RT81, RT80, RT53 have this function, this can help radios connect the repeater, to expand the alling distance.

What is the Keypad lock function of digital walkie-talkie?

Keypad lock function Keypad lock function prevents misoperation and is convenient and quick. This function is widely used in construction, construction and other scenes to facilitate walkie-talkie users to use the walkie-talkie more effectively. Like Retevis RT72 RT83 RT82 all have this function, very fit for busy use.

What is the Clone function of digital walkie-talkie?

Clone function clone/copy frequency. Clone the programmed data of the radio to another walkie-talkie of the same model. like Retevis RT43 and RT80 have clone function, you can clone the programmed data of the radio to another,very efficient.

Each function of the walkie-talkie corresponds to different needs and can meet the needs of different scenarios. Of course, you can also customize the walkie-talkie according to your needs and functions. If you have any needs or suggestions, please contact us: info@ retevissolutions.com
