🔍 Key Concepts

• GMDSS Radio Operator License vs. Radio Maintainer License – what each is authorized to do • Difference between user-level servicing (like changing paper, fuses, batteries) and technical adjustments • How maintenance actions might affect the calibration or proper operation of GMDSS equipment

💭 Think About

• Look at each option and ask: does this task simply restore normal use, or could it change how the equipment is technically adjusted or calibrated? • Which task would normally require specialized test equipment or technical knowledge to ensure the station still meets regulations after the work is done? • For each choice, decide if it sounds like routine ‘operator’ work, or in-depth ‘technician/maintainer’ work.

✅ Before You Answer

• Verify which functions are normally allowed for a GMDSS Radio Operator without a separate maintainer/technician qualification. • Identify which option involves changing internal settings or technical parameters, not just replacing or resetting simple components. • Make sure the task you select is one that, if done incorrectly, could directly affect the proper operation and compliance of the GMDSS station.
