Intuitive user interface, display and white illuminated buttons
ICOM's handy user interface is used in a lot of marine devices and offers very intuitive operation. A turning knob and four navigational keys offer fast and easy access to the desired functions. The contrasting white background LC-display and precise keys match the design perfectly.

Active Noise-Canceller
The integrated noise-cancelling technology works while sending and receiving and can reduce background noise by up to 90%. That increases audibility - hear better and be heard better.

Integrated GPS receiver
The integrated GPS receiver shows the latest position as well as the time and can be used to make DSC calls.

Class D-DSC integrated
The integrated DSC surveillance function monitors the activity on channel 70 (DSC-channel), also during the reception on another channel. The DSC functions include: distress signal, individual and group calls, calls to other ships, request for position/calls for information, polling request and DSC test calls.

With the optional COMMANDMIC™ HM-195GB you can operate the IC-M423G remotely and use all its functions. Additionally, both devices are useable as an Intercom. Matching the IC-M423G, the HM-195GB has the same white background lighting of the display and the keys.

10 W NF-performance, megaphone function and fog horn
The IC-M423G has a 10-W-NF-amplifier that amplifies the NF-signals over additional external speakers. With the megafon function it is possible to make clear announcements to the deck personnel and other boats. The fog horn can also be used via external speakers.

Standard NMEA-Interface
When an external GPS receiver is connected, the latest position and time are displayed on the IC-M423G. Position data from other ships are being transmitted over the NMEA0183 connection of the IC-M423G to external navigation devices.

Hervorragende Qualität und komfortable Features
I bought this device because you can connect a daughter device here. It is important to me to spark in the cockpit of the yacht and not always go to the basement to call the lock master. The ICOM is now installed and put into operation. Programming the MMSI and ATIS is easy and safe. The controls and buttons have a rich, high-quality click. The menu structure is clear and the orientation in the functions is easy. The noise reduction function is particularly impressive. Without any background noise or crackling, the voices can be heard from the ether as from the hi-fi system at home. So it was absolutely worth spending € 100 more, not having bought a discount spark, and receiving a lot of convenient advantages in sea-going communication. My recommendation for this compact device.

Gute Qualität, einfach zu bedienen.
With Icom you are always right, and with this device again special. The menu structure is as clear as the whole operation. What you need technically is in or out. A very good device.

I am a new customer at SVB. The wide range and the market conditions made me curious. The DSC system was delivered promptly and safely packaged, with German user manual (on the website was only the English mentioned and offered for download). Any time.
