Features:
DMO Dual Time-slot Communication, multiply efficiency
Realizes 2 talk paths on a frequency at the same time, multiply the efficiency and doubling the frequency utilization. Ensure real-time communication at peak service hours
Digital-Analog compatibility, Value-added experience
Support for compatibility with existing conventional analog products or systems, to ensure a smooth transi- tion from analog to digital products, thereby improving product utilization.
Digital voice, clear and loud
Digital Speech Error Correction Processing (AMBE+2TM) enables voice with superior clarity and performance. Provide clearer voice quality than analog radios, regard - less of the usage environment
VOX feature, release hands
The special VOX voice-activated feature can be voice triggered to make calls with audio accessories, which is particularly suitable for users who can't operate the PTT button to make calls
Emergency Alarm
Emergency alarms have the highest priority and can be used to send alarms to companions and the control center when an emergency situation is encountered.
OLED Display, Easy and Flexible Operation
OLED display interface with visual icon display and humanized menu operation make reading and control more convenient and flexible.
High Capacity Li-poly Battery
Equipped with 260OmAh lithium polymer battery can work for up to about 25 hours to meet customers' working needs.
Voice Encryption to Ensure Users' Communication Security
The function provides basic voice encryption to safeguard users' communication security.
Military Quality, Stable and Reliable
The product is IP54 and MIL-STD-810 C/D/E/F/G compliant; the quality testing includes drop, high and low temperature, humidity, dustproof, and vibration; the product stillfunctions properly in busy commercial service when accidental drops or showers.
More supplementary services to provide richer application experience
The hardware is newly upgraded to support a variety of services such as remote monitor, remote detection, call alert, remote kill, remote revive, etc., providing users with richer application experience.
OLED Display Advantages
The ultimate visual experience :Each pixel of the OLED display emits light independently, achieving near-perfect black and high contrast.Even under strong outdoor light, the signal information on the screen can still be clearly seen and will not be blurred due to reflection or excessive light.

High and low temperature resistance ensures all-day operation
Environmental adaptabilityI: The OLED display operates stably in a wide temperature range and can work normally in an environment of -40 ° C to 85 ° C. Its low blue light feature also reduces harmful blue light radiation, which helps relieve visual fatigue from prolonged use.

Al-based Noise Cancellation
The built-in 36mm diameter speaker and advanced Al-based Voice Recogni- tion technology deliver louder, clearer audio by eliminating unwanted ambient noise, reducing distortion and suppressing whistling caused by other devices in close proximity to each other. Ambient noise will no longer slow down communications and users can hear and be heard wherever they are.

GPS positioning, your location Anytime, Anywhere
The built-in GPS module can receive satellite signals in real time to deter - Imine the precise location of the device. This is particularly important for sce-narios such as team management, wilderness exploration, and emergency rescue. In emergency situations, the GPS positioning function can help quickly determine the specific location of the rescuers, improving the efficien - cy and safety of the rescue operation.

U-PoC self-build platform dispatching system can Tracking LTE and DMR radios same time.
DMR radios send GPS location to LTE& DMR in one radio like our LTE-CDR700UV/ LTE-DR880UV to show locations on map. And also LTE& DMR in one radio, can communications with LTE/Dual band DMR/ Dual band Analog same time. For connecting all communication models.

Bluetooth 5.0
DR-30oA supports Bluetooth; it is fast connection, high compatibility, wide coverage, stable, no lag, and zero delay on calls.

Extended Communication Coverage
DR-30oA utilizes a high-sensitivity receiver module and a high-efficiency monopole antenna to enhance signal penetration, providing good calls in rooms with weak signals, and maintaining stable performance and RF power output in low battery conditions.
In addition, the monopole antenna has a unique thicker thread design that is less prone to breakage and bending, which helps to increase the antenna's life, as well as increase radiation efficiency and extend radio communication coverage.

DR-300A
Adopting humanized appearance design, Al-based Noise Cancellation technology, clear digital audio, with automatic roaming, GPS, Blue-tooth, digital trunking and other optional features, DR-300A provides solid and reliable communication guarantee for emergency communi-cation and management dispatching of users in business, manufactur-ing, railroad, airport, hotel, shopping malls, security, entertainment venues, construction sites and other industries.
