Retevis RT80 Inverted Screen DMR Walkie Talkie

The RT80 is a DMR handheld walkie-talkie designed on the basis of Time Division Multiple Access (TDMA) technology. It supports three modes: digital, analog and digital-analog hybrid, and is compatible with existing conventional analog and DMR-based walkie-talkies. Except It's functions, the samll size, suitable for single-handed operation, easy to carry, ABS shell can protect the product good fall.

Retevis RT80 Special feature:

1. Support mixed digital-analog reception, digital-analog hybrid scanning

You can set the channel type to mixed mode by software or keyboard operation, that is, a channel (frequency) can receive both digital signals and analog signals (which signal is sent first and which type of signal the current transceiver receives)

2. TDMA dual-slot technology

We know, in simplex mode, the time slot is not worked, no matter what slot we select, it is doesn't matter for communication. In repeater mode, we must select the same slot, then you can communicate with each other. It just like increase the frequency utilization.

3. Radio function

You can listen to colorful news and entertainment programs in your spare time.

4. Rich keyboard operation function

1) Through the keyboard operation, set the options of the side buttons;

2) manually modify the walkie-talkie ID;

3) Manually increase the contact (single call, group call, all call)

5. Batch import contacts

You can import or export the contact list via software, fill in the contacts in the exported EXCEL template, call type, ID is good, import to the software, write frequency to walkie talkie. (Note: Only less than 999 contacts can be imported, when more than 999, the software will be promot error.)

6. Inverted screen

Can be defined by the side of the key, open the screen upside down, the screen can be rotated 180 °, when the radio hung in the shoulder position, you can easily observe the screen dynamics.
