Entering a Blaupunkt code
On most Blaupunkt radios, preset buttons 1–4 set the four code digits (each press increases the digit). Confirm with the button described in the manual – often 5, 6 or a long press on a seek arrow. After wrong codes the display shows a waiting time or OFF; leave the radio on until it asks for the code again (locked radio).
