Turn on the radio. The indication appears on the radio "CODE" and four fields, with the left field blinking.
Use station setting keys 1 to 0 to enter the secret code number. In this case, the entered code does not appear on the indicator.
After entering the first digit of the code, the second field starts flashing, then the third and then the fourth field.
When the correct code is set on the indicator, the radio goes into normal operation.
Attention: After two unsuccessful attempts to enter the code, a flashing message appears on the indicator "CODE". After the third unsuccessful attempt to enter the code, the waiting time increases to 15 minutes and the message appears on the indicator "CODE PAUSE". During the waiting time, the radio may remain switched on, after which the entry of the code number may be repeated.
If the waiting time is interrupted due to a power failure, a new countdown starts after power is restored.
