The alpha keypad is used to?

• A. Enter a frequency
• B. Select from 12 buttons
• C. Lock onto a signal
• D. Adjust power

Answer: (B)

The alpha keypad is used to quickly select from a fixed set of options, typically a group of pre-programmed buttons. Each key corresponds to a preset item, such as a channel or frequency, so pressing a single key instantly selects that preset without having to enter numbers manually. This speeds operation and reduces entry errors when you need to switch between common configurations.

It isn’t for entering a new frequency (that would require a numeric keypad or a different input method), nor for locking onto a signal (that’s a tuning or lock function), and it isn’t used to adjust power (power controls are separate). The alpha keypad’s purpose is straightforward selection from predefined choices.
