The IC-F1000D/F2000D can program Type-D single site trunking and digital conventional modes as well as analog mode per channel. The IDAS digital mode employs 4-level FSK modulation and the NXDN™ common air interface, offering true 6.25kHz spectrum efficiency, higher security and better audio clarity – even at the fringes of the communication range. The following IDAS features are programmable: PTT ID (TX), Individual/group calls, Radio check (RX), Stun/Kill/Revive (RX), Remote monitor (RX), Emergency (TX), Call alert (RX), Digital voice scrambler (15-bit), Status Call (Power ON/OFF status and GPS request), Voting scan for multi-site conventional operation To assist in worker safety, the IC-F1000D/F2000D has three emergency related functions: motion detection, man down and lone worker functions. If one of these functions are activated, the transceiver automatically enters an emergency phase and starts counting down to send an emergency signal. The built-in motion sensor detects its position and states motion and non-motion.
