4. Setup

4.1 Battery Installation

1. Ensure the radio is powered off.
2. Locate the battery compartment cover on the back of the radio.
3. Unlatch or unscrew the cover as indicated by the markings.
4. Insert the BP-306 Li-Ion battery, ensuring the contacts align correctly.
5. Securely close the battery compartment cover, ensuring it is watertight.

4.2 Charging the Battery

1. Connect the BC-242 AC adapter to a power outlet.
2. Plug the AC adapter into the BC-251 rapid desktop charger.
3. Place the IC-M94DE radio into the BC-251 charger cradle. Ensure the charging contacts on the radio align with those in the cradle.
4. The charging indicator on the charger will illuminate, typically red during charging and green when fully charged.
5. A full charge typically takes several hours. Do not overcharge the battery.

4.3 Antenna Attachment

2. Tighten it securely by hand, but do not overtighten.

4.4 Initial Power On

1. Press and hold the power button (usually marked with a power symbol) until the display illuminates.
2. The radio will perform a self-test and display the current channel.
3. Adjust the volume knob to a comfortable listening level.

5. Operating Instructions

5.1 Basic Operation

• Power On/Off: Press and hold the power button.
• Volume Adjustment: Rotate the volume knob clockwise to increase, counter-clockwise to decrease.
• Squelch Adjustment: Use the dedicated squelch button or menu option to adjust the receiver sensitivity and eliminate background noise.
• Channel Selection: Use the UP/DOWN arrow buttons to change channels. Press the '16' button for instant access to Channel 16 (distress and calling).
• Transmit (PTT): Press and hold the Push-To-Talk (PTT) button on the side of the radio to transmit. Release to receive.

5.2 Digital Selective Calling (DSC)

The IC-M94DE features integrated DSC for automated distress and safety calls.

• Distress Call: In an emergency, lift the protective cover on the back of the radio and press the red DISTRESS button for several seconds. This will transmit a distress alert with your vessel's position.

Figure 5.1: This screen indicates an active distress call, showing the radio is waiting for acknowledgment and the time until the next retransmission. It also provides options to cancel, resend, or pause the distress signal.

• Individual/Group Calls: Use the menu to initiate individual or group DSC calls to other vessels with known MMSI numbers.
• Receiving DSC Calls: The radio will alert you to incoming DSC calls. Follow the on-screen prompts to respond.

5.3 Automatic Identification System (AIS)

The integrated AIS receiver displays real-time vessel traffic information on the screen.

• Viewing AIS Targets: Access the AIS display mode through the menu. The screen will show nearby vessels as icons, along with their range and bearing.

Figure 5.3: Another view of the AIS display, this time with a 3 nautical mile range, illustrating how the radio visualizes surrounding vessel traffic for enhanced situational awareness.

• AIS Target Call: Select an AIS target on the display to initiate a direct DSC individual call to that vessel.

5.4 GNSS (GPS Receiver)

The integrated GNSS receiver provides accurate position information and navigation capabilities.

• Navigation Function: Use the navigation menu to set a waypoint and receive guidance to that location.
• Waypoint Storage: The radio allows you to store up to 50 favorite points or fishing destinations as waypoints.

5.5 Float'n Flash and MOB Auto Set

If the IC-M94DE is accidentally dropped into water, it will float, and its LCD screen, keys, and the distress button on the rear panel will flash, making it easier to locate and retrieve. If the distress button is pressed while the Float'n Flash function is active, it will automatically transmit a Man Overboard (MOB) distress signal.

5.6 AquaQuake Draining Function

This function helps to clear water from the speaker grille, preventing audio degradation after the radio has been exposed to water. Activate it via the menu or a dedicated button if available.

5.7 Active Noise Cancellation

The built-in active noise cancellation technology reduces background noise in both transmit and receive audio, ensuring clearer communication even in loud marine environments.

6. Maintenance

• Cleaning: Wipe the radio with a soft, damp cloth. Do not use abrasive cleaners or solvents. For saltwater exposure, rinse thoroughly with fresh water and dry completely.
• Battery Care: To maximize battery life, avoid fully discharging the battery frequently. Store the battery in a cool, dry place when not in use for extended periods.
• Storage: Store the radio in a dry, temperate environment away from direct sunlight and extreme temperatures. Ensure the battery is partially charged (around 50%) for long-term storage.
