If the internal device identifier (CANDICE-4 vs. CANDICE-7, device version, etc.) is inconsistent, wait until the corresponding device is mentioned by the voice and at that moment press anywhere on the touch screen. Alternatively, you can type the appropriate letter on an attached USB keyboard.

Connect a USB keyboard, set up the supply voltage and plug the USB stick with the firmware and instantly press the -Key on the keyboard. Now, you will hear the voice. Please follow the instructions above.
