Navigation and AIS Integration
- GPS Connectivity: When an external GPS receiver is connected, your current position and time are displayed on the Command Mic IV.
- NMEA 0183: DSC information received from other vessels can be transferred to a compatible navigational device via NMEA 0183 connectivity.
- AIS Target Call: When connected to the optional MA-500TR Class B AIS transponder, the AIS target call function allows for individual DSC calls directly from the MA-500TR.
Scanning Modes
The radio supports Dual Watch, Tri Watch, Priority Scan, and Normal Scan functions to monitor multiple channels effectively.
Maintenance
