On the reset screen of the Yaesu FTM-300DR, the "option" refers to different types of reset actions you can perform on the radio. These options typically include:

• Factory Reset: Returns all settings to the factory default, erasing all user configurations and memory content.
• Preset: Allows preset registration.
• Recall Preset: Recalls a previously saved preset.
• Memory Channel Reset: Erases all registered memory channels.
• APRS Reset: Resets APRS settings to default.
• Clone: Clones the radio settings to another unit.

These options are selectable from the reset menu accessed via the setup menu, allowing you to choose the specific reset function you want to perform

. To perform a factory reset, for example, you press and hold the [F(SETUP)] key, navigate to RESET, then select "1 FACTORY RESET." After confirming, the radio erases all information and restarts, showing the call sign input screen

. Thus, the "option" on the reset screen is the specific reset function you want to apply to the radio's settings or memory.
