Professional Two way Radio Supplier
Working in the potentially harsh environments such as construction sites, harbors, manufacturing or petrochemical plants need a reliable and durable two-way radio to guarantee safety and enhance working efficiency. DMR portable radio DP890 provide super audio quality, versatile functionality, durability, security and flexibility to solve problems confronted in the work area, creating great operating value.
Feature
Rugged Design
DP890 is strictly designed to meet IP67 and MIL-810C/D/E/F/G standard, ensuring good performance in potentially harsh environments such as harbors, manufacturing plants, petrochemical factory and construction sites.
Durable Battery
Two-time slot transmission reduces transmit time in half and thus increases talk time longevity. 2000mAh battery supplied in standard package ensures at least 14 continuous working hours in analog mode and 16 hours in digital mode.
Improved Audio Quality
Digital error-correction technology rejects noise and static, providing consistent audio quality throughout the coverage area and in challenging low lying areas..
AMBE+2TM vocoder further improves speech communication. 1.6W audio output and a 40mm diameter powerful speaker ensure louder and crisper voice communication.
Double Capacity Repeater Mode
DP890 can work with a single repeater to achieve twice the traffic capacity without relicensing or rebanding, meaning two voice communications or one voice communication and one data transmission can transmit at the same time in one channel.
Analog/Digital Mode
DP890 can operate both in analog and digital mode by channel switching or mixed mode scanning. DP890 can be used on the existing analog system, and when your budget allows, transitioning to digital at your own pace.
Versatile Services
DP890 provides versatile services including individual call, all call, group call, emergency call, radio enable & disable decode, remote monitor decode, radio check decode, call alert decode, facilitating high-efficient communication and management.
Text Message
When it is not convenient to have voice communication, text message offers a quiet communication choice. You can choose one of the maximum 50 preset messages to initiate by one touch buttons.
Basic Encryption
The 16-bit digital encryption technology ensures only the intended person can hear the communication.
One Touch Access
Support one touch access to send a digital call or a message, providing a quick way to send a call or a message under emergency situation.
DTMF Encode and Decode
Supports DTMF encode and decode in analog mode, providing better compatibility with existing analog radio system.
