How can you re-select the previously used frequency?

• A. Use the Swap button on the CCP
• B. Configure in the RTS panel
• C. Select Swap Control on the EUFD
• D. Re-tune manually on RF panel

Answer: (C)

When you want to jump back to the frequency you were just using, the quickest and safest way is to use the Swap Control in the EUFD. This control is specifically designed to recall and reselect the most recently active frequency (and its associated settings) with a single action. It streamlines the switch, reduces the chance of entering the wrong value, and avoids the slower, manual retuning process.

The other options don’t perform this recall action. A swap control on another panel may alter something else or only swap between two items, not preserve and reselect the exact last-used frequency. The RTS panel is focused on remote signaling and control, not frequency recall. Manually retuning on the RF panel works but requires entering the frequency again and fine-tuning, which takes more time and increases the chance of error.
