How do I run the appliance self-test on my Bosch fridge-freezer?

Switch off the appliance and wait 5 minutes, then switch it back on. Within the first 10 seconds after switching on, press and hold the super button for 3–5 seconds to start the self-test. If 2 audible signals sound at the end, the appliance is OK; if 5 audible signals sound and the super button flashes for 10 seconds, contact customer service. (Page 18)
