- both servos go to their (almost) centre position
- a series of beeps is heard

key to be pressed. If so, YETI goes into calibaration mode.

a short beep being heard once.

- that YETI has received an infrared signal, so it’s
infrared receiver is most probably okay.

mode. Press the ENTER key in hyperterminal so YETI exits
