JIS Grade 7 Waterproof Protection
The IC-M421, including the microphone, has waterproof protection, equivalent to JIS waterproof specification grade 7 *.
Equivalent to IPX7 of the corresponding international standard IEC 60529 (2001). 1m depth for 30 minutes.

The IC-M421 is extremely compact measuring only 164(W) x 78(H) x 139.5(D) mm.

Built-in Class D DSC
The IC-M421 has a built-in Ch 70 (DSC channel) receiver, which monitors activity, even while you are receiving another channel. When in an emergency situation, an automated distress call can be sent with a touch of a button.

Digital Selective Calling Features
The DSC uses a unique ID (MMSI code) similar to a telephone number. So you can make a contact with intended ID station or group directly or all ships in the area. When connected to an external GPS receiver, the position request and position report functions allow you to exchange ship's position information. The polling (request/reply) function checks whether a specific ship is in communication range. A total of 100 address IDs can be programmed with 10-character address name and up to 40 received DSC messages (20 distress and 20 other calls) can be stored.

Large LCD With Dot-Matrix Characters
The IC-M421 has full dot-matrix display with up to 168-character capability that allows you to see a host of information such as channel number, channel name, position and DSC data etc. With the backlit display, the large buttons and knobs, the IC-M421 is easy to operate.

Loud Speaker Audio
The IC-M421 has a large speaker grille, which gives excellent audio quality from the front-mounted speaker. This results in clear reception, even over wind or engine noise.
