starts flashing again. In this state the code number can be written over as frequently as desired. A
correction can be made only by entering the complete code number again.
4. Confirm code number:
Press TUNE, AUTO/SEEK or SC button. The radio automatically switches on and indicates the radio
station or frequency stored with station button 1.
5. If an incorrect code number is entered and confirmed, the word "CODE" appears again on the display. If
an incorrect code is entered three times the word "WAIT" appears on the display and the radio locks up
for approx. 10 min. If the code is entered incorrectly three times again the radio locks up again for 10
min. Three more incorrect entries (a total of 9 incorrect attempts) increase the lock-up time to 60 min.
Another three incorrect entries lock up the radio for another 60 min.
The waiting time runs only when the radio is switched on.

switching on the ignition the word "CODE" appears on the radio display.
2. The code number for this radio is given on the included code card.
3. Enter the code number with the station buttons, e.g. number 1 = station button 1..
4. After entering the first digit the word "CODE" disappears and the number entered is displayed followed
by four dashes. Enter the next numbers with the corresponding station buttons. After entering the five
digit code number compare the code number with the number on the display. At this point the code
number can be written over as frequently as necessary for correction. If the wrong code number has been
entered, enter the entire code number again.
5. Confirm entry of correct code number with " < " or " > " button.
6. If the wrong code number has been entered and confirmed the word "CODE" appears again on the display
and the code must be entered again.
7. After entering the code incorrectly three times the word "WAIT" appears on the display and the radio is
disabled for approx. 10 minutes. After entering the incorrect code three times again the radio is disabled
for approx. 60 minutes.
The disable time runs down only with the radio switched off.
