When is the hand signal of a hand held to ear used by a Rescue Swimmer (RS)?

The hand signal of a hand held to the ear by a Rescue Swimmer is used to request radio communication. This gesture signifies the need to establish contact and communicate important information. In rescue operations, effective communication is critical for coordination and safety, making this signal vital.

This visual cue signals that the swimmer needs to relay or receive information via radio, which is particularly important in high-pressure situations where verbal communication may not be possible. The specific action of bringing a hand to the ear universally conveys the need for auditory communication, thus eliminating ambiguity and ensuring that vital instructions or updates can be exchanged rapidly.
