RT81 Dual Time Slot High Power IP67 UHF DMR Radio

Retevis RT81 Dual Time Slot UHF High Output Power IP67

 IP67 Waterproof radio Long-range Radio

 The design of IP67 dust-proof and waterproof preventing solid objects and water from damaging the walkie-talkie. Allows you to use RT81 in complex environments.

Digital Encryption

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

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.

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.

Rugged radios

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

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.

Private/Group Call/All Calls

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

Digital /Analog handheld long-range Radio

Since the RT81 DMR waterproof radio 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 the meantime reduced cost of equipment replacement.

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.

Dual Time Slot

RT81 handheld DMR radio supports a repeater that is compatible with digital DMR and analog repeaters and extends the communication range.Dual Time Slot expands the channel capacity and extends the communication distance.

UHF

UHF in the high-frequency band has better penetration and is more suitable.
