When should you release the MODE button during startup?

• A. When audio beeps once
• B. After the display shows ready
• C. After continuous beeps
• D. Immediately after power-up

Answer: (B)

During startup, the device runs initialization and a self-test, and it only accepts user input once it signals readiness. Releasing the MODE button after the display shows ready ensures the mode selection is captured in a stable state—the firmware has finished loading and the system is in normal operating mode. If you release immediately after power-up, the device may still be initializing and could misread the input or enter a boot/diagnostic state. Relying on beep cues isn’t as reliable because beep patterns can indicate progress or errors but don’t guarantee full readiness. Waiting for the ready display ensures the correct mode is registered and avoids misinterpretation of startup signals.
