Check that the kit as received is complete. It must include:

3. Assembled MCU board (BNC connectors not mounted).

4. Assembled Display board (without the button of the rotary switch).

Note: the LCD has a protective film so transparent that it can go

unnoticed. It has no tab, but it can be easily peeled off by gently

lifting it at an angle with your fingernail.

5. Four PCB-mount BNC connectors.
