IC-U400 Options

Some versions cannot use all the options listed below since type approval for the IC-U400 varies between countries. Ask your Icom dealer which options are available.
  • CK-12 REMOTE CABLE KIT: Allows you 6 m (19.7 ft) separate installation of your IC-V100 front panel and main body in the vehicle.
  • HG-10 MICROPHONE HANGER BOX: Provides monitoring when operating with the tone squelch function even if the microphone is left hanging on the microphone hanger.
  • HM-37 DTMF MICROPHONE: Heavy-duty hand microphone with DTMF keyboard.
  • HM-38 HAND MICROPHONE: Heavy-duty hand microphone.
  • IC-PS30 AC POWER SUPPLY: Allows you to use the IC-V100 through AC power source. Equipped with a DC power cable and 3 extra DC output connectors. Output voltage: 13.8 V; Max. current drain: 25 A
  • SP-5 EXTERNAL SPEAKER: Can be easily installed in any part of your vehicle. The same type as supplied with the IC-V100. Input impedance: 4 ohms. Max. input power: 5 W
