ICOM M423G FIXED MOUNT VHF RADIO WITH GPS

Description

Built-in GPS Receiver
The built-in GPS receiver shows your current position and time and can be used for DSC calls. GPS data source is selectable from internal and external GPS (and GPS-OFF).

White Backlight LCD and Laser-cut Keypad
The new white backlight LCD matches the modern leisure boat design.

New HM-205B/SW Speaker-Microphone
High-grade speaker-microphone, HM-205B/SW is supplied with the IC-M423G. The HM-205B/SW has channel Up/Down, channel 16/call channel and transmit power (Hi/Low) buttons and a large 45mm diameter speaker.

Active Noise Cancelling
Using digital signal processing technology, the built-in active noise canceller reduces background noise to up to 90% in the received signal and 30% in the transmitting signal.

Intuitive User Interface
The menu system provides easy and intuitive operation. The bottom line of the dot-matrix display shows the software key functions which can be toggled with the left and right buttons. The directional keypad allows you to perform various operations and settings.

10W Loud Audio, Public Address & Foghorn
The IC-M423G has a built-in 10W amplifier that increases the audio output from an external PA speaker. The public address function allows you to make an announcement from the microphone like a loudspeaker, and the foghorn can also be emitted from the external PA speaker.

Built-in Class D DSC
The built-in DSC watch function monitors Ch. 70 (DSC channel) activity, even while you are receiving another channel. DSC functions include distress, individual, group, all ships, urgency, safety, position request/report, polling request and DSC test calls.

AIS Target Call
When connected to an optional MA-500TR Class B AIS transponder, the AIS target call function allows you to make an individual DSC call without having to manually input an MMSI number.

MarineCommander Compatible
When connected to the MarineCommander, the received DSC message pops up on the multifunction display.

IPX7 Submersible Protection (1.0m depth for 30 minutes)
The ICOM-M423G withstands submersion in up to 1.0m depth of water for 30 minutes. It is equivalent to the IPX7 standard.
