Before starting the installation process, verify that all core and optional parts are available in the inventory box. Core System Elements

: Install the ATU externally or in an overhead locker as close as possible to the base of the transmit antenna. Minimizing the length of the single-core lead wire prevents high RF losses and accidental cabin radiation.

| Symptom | Possible Cause | Suggested Remedy | | :--- | :--- | :--- | | | Switch off, cable loose, fuse blown, polarity reversed. | Check power switch, cable, fuse (check the 3A fuse for the main unit and the 5A fuse for the power supply). Ensure 24V is present. | | No power on the screen | Power supply issue to the display. | Check for +12V at a specific point (U8 of T-025) and +5V on the DC-DC converter on the CPU board. | | Data not received (NBDP) | Antenna connection or internal signal issue. | Check antenna connection. Check for a 3.2V signal at pin 3 (IC4 of T-022) and verify that a 1.7KHz±85Hz signal is present on CN8 of T-022. | | Data not transmitted (NBDP) | Connection issue or missing modulation signal. | Check the cable between the transceiver and the SN-100 terminal. Verify that a 1.7KHz±85Hz signal is present. | | DSC Selftest shows "Receiver: Error" | Antenna or receiver issue. This can be complex. | The error may appear even if the antenna is fine and calls go through. Check all antenna connections. If the error persists, run a full diagnostic check. |

The is a high-performance 150W MF/HF radio transceiver. It is designed for maritime communication and compliance with GMDSS requirements. Proper installation ensures optimal performance, system reliability, and safety at sea. 1. System Components Checklist

Mount all components at least 1.5 meters away from magnetic steering compasses to avoid interference. 2. Mounting the Hardware Main Transceiver and Control Unit Before starting the installation process, verify that all

Connect the top high-voltage terminal of the SAT-1150 ATU to the base of the antenna using a heavily insulated GTO-15 high-voltage cable. Keep this run under 1.5 meters. Ensure it does not run parallel to other wiring or metal structures.

Use a high-quality 6-meter to 8-meter fiberglass whip antenna.

From the main SYSTEM SET menu, select 3. Data-Set to input the current date, and 4. Time-Set to input the correct UTC time. The radio logs received DSC messages with this information. | Symptom | Possible Cause | Suggested Remedy
