Ultra Compact Body, Flexible Installation
The IC-M330/G has a palm-sized compact body (W×H×D; 156.5 × 66.5 × 88.2 mm; 6.2 × 2.6 × 3.5 in). The radio can be installed in limited space.
New Speaker Delivers Dynamic, Clear Audio
A new speaker design delivers dynamic and clear sound over a wide bass and treble range. The IC-M330/G provides a distortion-free clear audio even at full volume.
Built-in Class D DSC
The radio monitors CH 70 continuously, 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.
Class Leading Receiver Performance
The radio provides reliable communication in RF busy environment like a marina. (Selectivity and IMD: more than 70 dB)
Intuitive Operation with Icom Marine User Interface
A combination of the directional keypad and soft keys provides simple, smooth operation. Most used functions are assigned to soft keys for quick one push function access.
GPS Receiver Built-in (IC-M330G)
A built-in GPS receiver provides your location, bearing and speed by using information from GPS, GLONASS and SBAS. The acquired position information can be used for DSC calls.
Made in Japan Quality and Reliability
All Icom products are tested to pass rigorous in-house tests as well as environmental tests at the Wakayama Icom plant before shipping. Our world-leading products and quality is tradition.

Ingress Protection (IP) Code
Ingress Protection (IP) ratings define the level of protection provided by enclosures to prevent the ingress of foreign objects (dust) and liquid into the electrical equipment.
International Standard IEC 60529 outlines an international classification system that describes the sealing characteristics of electrical equipment.
The classification system uses the “IP” code, or “Ingress Protection” code, to define the level of seal.
An IP number contains two numbers (i.e. IP67) in most instances which relate to the level of protection provided by an enclosure or housing.
Either number may be shown as “X” (i.e. IPX6 / IP7X) to indicate the “X” part is not tested.
Degrees of Solid Particle Protection – 1st Digit
|IP6x||No ingress of dust; complete protection against contact. (Dust tight)|
|IP5x||Protected from the amount of dust that would interfere with normal operation. (Dust protected)|
Degrees of Liquid Ingress Protection – 2nd Digit
|IPx8||Protected against continuous immersion in water.
Depth and duration specified by model.
|IPx7||Protected against temporary immersion in water for 1 m (3.3 ft) for 30 minutes|
|IPx6||Protected against water projected by powerful jets from any direction.
100 L per minute by a powerful jets (12.5 mm) for 3 minutes.
|IPx5||Protected against water projected by jets from any direction.
12.5 L per minute by a nozzle (6.3 mm) for 3 minutes.
|IPx4||Protected against water splashed against the equipment from any direction|
