Introduction
The ICOM M330 series offers a compact design with robust performance and features, similar to the M324 series, but optimized for installations with limited space. This marine radio is equipped with essential functionalities for safe and efficient communication on the water.
Key features include the exclusive AquaQuake draining function, 25 watts of power, IPX7 waterproof rating, scan/select scan capabilities, and an intuitive user interface. Its dot-matrix display ensures clear readability, and the combination of a directional keypad and soft keys allows for simple and smooth operation. Most frequently used functions are assigned to soft keys for quick, one-push access.

Setup and Installation
The ICOM M330 is designed for easy installation, even in confined spaces. The package includes the M330 VHF unit, a mounting bracket, a power cord, and this user manual.
Initial Power On:
- Ensure the radio is securely mounted using the provided mounting bracket.
- Connect the power cord to a suitable 12-volt DC power source, observing correct polarity.
- Press and hold the black power/volume/squelch knob until the display illuminates and the unit powers on.
- The built-in GPS will automatically acquire position and time data. Allow a few moments for this process to complete.
Operating Instructions
Channel Selection:
- To change channels, use the CH up (▲) and CH down (▼) buttons located on the right side of the radio.
- For quick access to Channel 16 (the international distress and calling channel), press the blue 16/C button. This channel is crucial for communicating with the Coast Guard and for general distress calls.
- When operating in specific areas, such as Portsmouth Harbor, it is often required to monitor Channel 11 (VTS). Use the CH up/down buttons to navigate to this channel.
Volume Adjustment:
- To adjust the volume, simply rotate the large black knob (VOL/SQL/PWR) clockwise to increase volume and counter-clockwise to decrease it.
Squelch Adjustment:
- To adjust the squelch level (which filters out background noise), press the black knob once. The display will show "SQL".
- Then, rotate the black knob to adjust the squelch level. Turn it clockwise to increase squelch (reduce noise) and counter-clockwise to decrease it (allow weaker signals).
- Press the knob again or wait a few seconds for the display to return to normal operation.
Additional Features:
- AquaQuake Draining Function: This feature emits a vibrating sound to clear water from the speaker grille, ensuring clear audio even after exposure to water.
- Built-in Class D DSC: Includes a dedicated CH70 receiver for Digital Selective Calling, enhancing safety by allowing direct digital calls to other vessels or shore stations.
- Common NMEA Interface: Allows for external GPS/NAV connection, integrating navigation data with your radio.
- Tag Scan and Favorite Channel Functions: Customize your scanning preferences and quickly access frequently used channels.
- Dual/Tri-watch Function: Monitor Channel 16 and/or a call channel simultaneously for enhanced situational awareness.
Maintenance
To ensure the longevity and optimal performance of your ICOM M330 VHF Marine Radio, regular maintenance is recommended:
- Cleaning: Wipe the radio and microphone with a soft, damp cloth. Avoid using abrasive cleaners or solvents. For the speaker, utilize the AquaQuake draining function after exposure to water.
- Connections: Periodically check all cable connections for corrosion or damage. Ensure they are securely fastened.
- Waterproofing: Although IPX7 waterproof, avoid prolonged submersion or high-pressure water jets directly on the unit. Ensure all caps and covers are properly sealed.
- Storage: When not in use for extended periods, store the radio in a dry, cool environment away from direct sunlight.
Troubleshooting
If you encounter issues with your ICOM M330, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Radio does not power on. | No power, loose connection, blown fuse. | Check power cable connection, inspect fuse in power line, ensure battery is charged. |
| No audio or low volume. | Volume too low, squelch too high, speaker blocked by water. | Increase volume, decrease squelch, use AquaQuake function to clear speaker. |
| Cannot transmit or receive. | Antenna issue, incorrect channel, power output setting. | Check antenna connection, ensure you are on the correct channel, verify power setting (HI/LO). |
| GPS position not displayed. | No GPS signal, external GPS not connected or faulty. | Ensure clear view of the sky for GPS signal acquisition. If using external GPS, check connections and functionality. |
If these steps do not resolve the issue, please contact ICOM customer support or a qualified marine electronics technician.
