What should you do if applicable when establishing positive identification for a mobile radio unit?

When establishing positive identification for a mobile radio unit, including the location of the equipment is essential. This information helps clarify exactly where the mobile unit is situated and assists in ensuring that all parties involved in the communication are aware of the specific context. Providing the location plays a critical role in operational safety, response coordination, and effective communication, especially in situations where multiple units may be operating in close proximity. It allows for accurate tracking and aids in preventing misunderstandings that could arise from similar call signs or equipment types being in use.

While other elements may be useful in certain situations—such as crew member lists or the purpose of communication—location is vital for immediate identification and context in operational settings.
