🔍 Key Concepts

• GMDSS Radio Operator vs. GMDSS Maintainer – who is allowed to do what • Difference between simple operator checks/inspections and technical maintenance or internal adjustments • Regulatory limits on who may open, modify, or align radio equipment

💭 Think About

• Look at each choice and decide: is this an external/operational task or is it internal/electronic maintenance? • Ask yourself: which tasks could affect the transmitter’s performance, legal emissions, or safety if done incorrectly? • Think about what kind of training a Radio Operator normally has compared with a Radio Maintainer.

✅ Before You Answer

• Identify which options describe internal electronic work or alignment/adjustment of radio equipment – these normally require a maintainer or technician. • Check which options involve basic external inspection/housekeeping that an operator would reasonably do as part of routine watchstanding. • Make sure the option you choose does not require opening equipment or altering internal components, settings, or software.
