Support Bluetooth 4.2 standard access, support Bluetooth write frequency and Bluetooth call, the function makes the versatility of the product more extensive. The radio adopts 2.4 inch color LCD display, which makes the display information clearer even under strong light. Ergonomic design greatly improves the accuracy and comfort of operation. NXDN DIGITAL AIR INTERFACE AP25 radios employ NXDN, an FDMA digital air interface with AMBE 2™ voice coding technology, with forward error correction and unique filtering to obtain superior coverage even at weak RF signal strengths. The NXDN air interface is capable of fitting into both 12.5 kHz and 6.25 kHz bandwidth channel operation to ensure rock-steady frequency stability, exceeding all regulatory and emissions mask requirements in all bands. Support multiple working modes Trunking Mode (TM) It can support PDT/DMR/NXDN digital trunking communication system service, realizes voice single call, group call, broadcast call and rich trunking communication functions. Conventional mode (DM/RM) Fully support digital and analog services in the direct (DM) mode; Fully support digital and analog services in the relay (RM) mode;  Support multiple standard protocols It can support PDT/DMR/NXDN digital conventional, cluster standard communication protocol, convenient to meet the different needs of customers use environment and requirements to enable users to smoothly transition from analog communication system to digital communication system.  Bluetooth voice / data service (Optional) Support Bluetooth 4.2 standard access, support Bluetooth write frequency and Bluetooth call, the function makes the versatility of the product more extensive.  GPS/ Beidou/GLONASS positioning mode (Optional) Support GPS/Beidou positioning, which can be realized GPS/Beidou position information transmission, combined with command and dispatch software, can be intuitively view the location of people on the map and make voice calls with them.  Reliable and durable quality The quality of the radio meets the national military standard and the IP67 industrial protection standard, thus ensuring that the product structure is sturdy and durable, wear-resistant, antiaging, and can  exert excellent performance in a variety of harsh working environments  Explosion-proof version Ex marking: Ex ib IIC T4 Gb; Ex ib IIIC T130℃ Db AP25 EX version is specially designed for those who work in environments with explosive gas and combustible dusts, providing secure and reliable voice and data communication in the dangerous areas.
