    Thank you for purchasing the AR-DV1 SDR Digital Voice Receiver. AOR is pleased to present you with the AR-DV1, the FIRST software defined digital voice receiver to receive and decode virtually ALL popular digital modes such as MOTOTRBO™, DMR™, dPMR™, APCO P25, NXDN™, Icom D-Star™, Digital CR, Yaesu, Kenwood ®, and Alinco EJ-47U as well as conventional...

  • Page 7: Taking Care Of Your Receiver

    The AR-DV1 is designed to operate from a good quality regulated DC power supply of 10.8 to 16.0 V, which should be capable of supplying 1 A. Never connect the AR-DV1 directly to an AC power outlet.

    Note: For the search & scan functions to operate properly, it is very important to advance the squelch to cancel background noise. This is because the AR-DV1 believes that it has found an active frequency when the squelch opens and the “BUSY” indicator lights up. Advance the squelch control clockwise until the background noise is just cancelled;...
