1. RETEVIS RT81 Dual Time Slot UHF/VHF High Output Power IP67 Digital /Analog mode is compatible DMR two way radios.

2. RT81 IP67 Waterproof radio

The design of dust-proof and waterproof prevents solid objects and water from damaging the walkie talkie. Allows you to use RT81 in complex environments.

3.Digital Encryption

Secure communications are an essential requirement, especially for public safety applications, RT81 is equipped with 10-bit key data encryption, walkie talkie prevents eavesdropping and avoids interference to ensure secure communication.

4. Long Battery Life

Built-in 2200 mAh battery, an operating time of 15 hours in analog mode and 25 hours in digital mode, and is suitable for daily use.

5.Crystal Sound

Security personnel typically work in a busy, noisy environment. The sound quality of the walkie-talkie is especially important. Due to the built-in high quality speakers, the DMR walkie-talkie provides better noise cancellation. In a noisy environment, it is possible to communicate with others in better quality.

6. Sturdy Body

In the security process, it often happens that the walkie-talkie falls down by running. Therefore, there are certain requirements for the fall resistance of the walkie talkie. A robust shell with stronger protection against falls and earthquakes is more durable.

7. High/Low Power Selection

High power has a longer call range. Low power has a longer battery life. The selection between high and low power can be used flexibly, allowing you to choose the appropriate power in different situations.

8. Private/Group Call

For security, it is necessary to communicate. The walkie-talkie supports individual and group call with ID, by setting the frequency, time slot, etc. to meet complex communication requirements.

9.Digital /Analog

Since the walkie talkie is compatible with both analog and digital modes, it not only retains the analog radio function, but also has the advantages of digital radio, such as better radio performance and longer battery life, higher energy efficiency, and in the meantime reduces the cost of equipment replacement.

10. Dual Time Slot

The walkie talkie supports a repeater that is compatible with digital DMR and analog repeaters and extends the communication range.

The walkie talkie has three modes: simplex, repeater, and simplex dual time slot. In simplex mode, the walkie talkie communicates in different time slots, which improves communication efficiency. In Repeater mode, the walkie talkie increases the communication distance. Dual Time Slot expands the channel capacity and extends the communication distance.

 

11.Six Advantages of DMR

DMR technology offers six benefits, including doubling the capacity of existing licensed channels, backward compatibility with legacy systems, longer battery life, and increased energy efficiency that improves working efficiency, extends walkie talkie life, and reduces equipment replacement costs.

12. UHF/VHF dual-band radio

UV dual-band, UHF in the high frequency band has better penetration and is more suitable. Outdoors, in a more open environment, VHF in the low frequency band has better diffraction and is more suitable.

 

13. Application

RT81 high power dual-time radio for rescure, security, Firefighting
