What should you do if your DSC radio is not patched into your GPS?

Recording your position every four hours is essential in situations where your Digital Selective Calling (DSC) radio is not connected to your GPS. This practice ensures that you have accurate, up-to-date information about your vessel's location, which is crucial for safety and potential rescue operations if needed. In maritime communication, being able to provide your position enhances the effectiveness of distress calls and increases the chances of a timely response.

While other options may seem reasonable in certain contexts, they do not directly address the problem of a disconnected GPS. Calling for assistance without knowing your precise position could hinder rescue efforts. Shutting down the radio could eliminate your means of communication, further compromising safety. Changing the battery may be necessary if the radio is faulty, but it does not resolve the lack of GPS connection. Therefore, maintaining a record of your position is the most practical and immediate response to ensure safety and preparedness in such a scenario.
