How do you set your radio to the correct channel on the EF Johnson?

Setting your radio to the correct channel involves using the designator under which the specific frequencies are saved in the system. When operating an EF Johnson radio, each frequency is associated with a designated number or name, making it easy to access and switch between channels without needing to manually enter frequencies each time.

The system is designed for efficiency, ensuring that users can quickly navigate to the required frequency by selecting its designated label. This method is particularly beneficial during high-pressure situations where every second counts, as it minimizes the potential for errors that might occur if entering frequencies manually.

The other options suggest alternative methods that might not be applicable or practical for this specific radio model. For instance, while manually entering a frequency or setting to automatic configuration may work in other contexts or with different equipment, relying on preset designators streamlines the process and leverages the built-in programming of the EF Johnson radio.
