It features VOX functions with multifunction scan that supports up to 199 CTSSS/DCS channels. It operates via simplex or semi-duplex antenna on 136MHz to 174MHz VHF frequency range and 40MHz to 470MHz UHF frequency range at 5W VHF and 4W UHF power output, with an impedance of 50ohms at 7.2V DC.

The radio operates on a cathode darth-plate at a temperature range of -10 degrees to 55 degrees Celsius at 5W power output, with -65dB spurious emissions at 1.6A and a maximum deviation of +/-5kHz. Its audio output is rated at more than 0.5W with less than 10 percent distortion with 0.3kHz to 3kHz frequency response range.
