IC-M422 VHF Marine Transceiver
Built-in DSC watch function monitors Ch 70 (DSC channel) activity, even while
you are on another channel. In an emergency situation, a formatted distress call
can be sent at the touch of a button.
DSC uses a unique ID (MMSI code) similar to a telephone number, allowing you to
make contact with a specific boater or group of boaters in your area. A total of
100 address IDs can be stored with a 5-character name.
With an external GPS receiver, the IC-M422
VHF Marine Transceiver position request and position report
functions allow you to exchange ships position. The received position
information can be plotted on a third party GPS or other navigation equipment
which accepts NMEA data format. The polling (request/reply) function checks
whether a specific ship is in the communication range.
Use the hand microphone as part of a public address system and make an
announcement on-board or to shore through an external loud speaker or hailer.
The RX speaker function allows you to monitor the received audio from the loud
speaker or hailer while you are on the deck or tower.
The new optional COMMANDMICII™makes
it convenient for using the Icom IC-M422
VHF Marine Transceiver from a separate cabin or tower. It allows
you to control most functions* of the
Icom IC-M422 VHF Marine Transceiver, including remote power ON/OFF, PA and RX speaker functions.
*except DSC operation
The front facing speaker offers loud, crisp reception that is easy to hear, even
over engine or wind noise.
The local function turns ON the attenuator and gives you the option to reduce
interference from strong stations.
- Submersible*
(1m depth for 30 minutes.)
*Equivalent to IPX7, except cables.
- Large 2-digit channel with scrolling names
- 7-step keypad backlighting
- 4-step LCD contrast
- Dual watch and Tri-watch functions
- Super white and black versions available.
- Simple and easy tag scanning system
- NOAA weather channels with alert function
- Low voltage indicator for low battery alert
