Professional and easy to use / Mobile radio for your introduction to digital
The MD615 is a perfect first radio in the world of DMR communication. With its robust design and clear voice transmission, this compact mobile radio can be used in any application scenario. A variety of interfaces and Bluetooth connectivity guarantee optimum usability.
Both analog and digital channels can be configured with the MD615. You can easily switch your choice of channel between analog and digital. With the "A&D Auto Detect" feature, your radio monitors analog and digital modes simultaneously and automatically reacts in the correct mode. This enables an extremely smooth and simple migration from analog to digital.
You can program the MD615, adjusting the transmitting power to between 1 W and 25 W. Variants of the MD615 with a higher output rating can expand their communication range by a considerable amount.
Localization by GPS via the optional external GPS module permits position checks and real time position determination in AVL application. With the Bluetooth option, the radio can establish a wireless connection with various Bluetooth accessories.
MD615 supports the pseudo trunking mode, which increases the radio capacity without additional costs or frequency licenses. This means that two voice channels can be dynamically and automatically assigned to multiple communication groups on the same frequency.
The MD615 combines a robust external design, which complies with military standards and is protected against dust and moisture penetration in accordance with IP54, with a compact housing.
